==========
This directory holds a port of NuttX to the NXP/Freescale Sabre board
featuring the iMX 6Quad CPU.
This is a minimal port, used primarily for verifying SMP operation. More
recently, a port to the i.MX RT was added. This port has gotten more
support since it is better aligned with usage in embedded systems. The
i.MX6 and the i.MX6 share IOMUXing and some peripherals. It ought to be
a simple matter to backport some of the common drivers from i.MXRT to i.MX6.

Status
======
2016-02-28: The i.MX6Q port is just beginning. A few files have been
populated with the port is a long way from being complete or even ready to
begin any kind of testing.
2016-03-12: The i.MX6Q port is code complete including initial
implementation of logic needed for CONFIG_SMP=y . There is no clock
configuration logic. This is probably not an issue if we are loaded into
SDRAM by a bootloader (because we cannot change the clocking anyway in
that case).
There is a lot of testing that could be done but, unfortunately, I still
have no i.MX6 hardware to test on.
In additional to the unexpected issues, I do expect to run into some
cache coherency issues when I get to testing an SMP configuration.
2016-03-28: I now have a used MCIMX6Q-SDB which is similar to the target
configuration described below except that it does not have the 10.1" LVDS
display. Next step: Figure out how to run a copy of NuttX using U-Boot.
2016-03-31: Most all of the boot of the NSH configuration seems to be
working. It gets to NSH and NSH appears to run normally. Non-interrupt
driver serial output to the VCOM console is working (llsyslog). However,
there does not appear to be any interrupt activity: No timer interrupts,
no interrupt driver serial console output (syslog, printf).
2016-05-16: I now get serial interrupts (but not timer interrupts). This
involves a few changes to GIC bit settings that I do not fully understand.
With this change, the NSH serial console works:
MX6Q SABRESD U-Boot > ABEFGHILMN
NuttShell (NSH)
nsh>
But there are still no timer interrupts. LEDs do not appear to be working.
2016-05-17: Timer interrupts now work. This turned out to be just a minor
bit setting error in the timer configuration. LEDs were not working simply
because board_autoled_initialize() was not being called in the board startup
logic.
At this point, I would say that the basic NSH port is complete.
2016-05-18: Started looking at the SMP configuration. Initially, I verfied
that the NSH configuration works with CONFIG_SMP_NCPUS=1. Not a very
interesting case, but this does exercise a lot of the basic SMP logic.
When more than one CPU is configured, then there are certain failures that
appear to be stack corruption problem. See the open issues below under
SMP.
2016-05-22: In a simple NSH case, SMP does not seem to be working. But there
are known SMP open issues so I assume if the tasking were stressed more there
would be additional failures. See the open issues below under SMP.
An smp configuration was added. This is not quite the same as the
configuration that I used for testing. I enabled DEBUG output, ran with
only 2 CPUS, and disabled the RAMLOG:
+CONFIG_DEBUG_FEATURES=y
+CONFIG_DEBUG_INFO=y
+CONFIG_DEBUG_SCHED=y
+CONFIG_DEBUG_SYMBOLS=y
-CONFIG_DEBUG_FULLOPT=y
+CONFIG_DEBUG_NOOPT=y
-CONFIG_SMP_NCPUS=4
+CONFIG_SMP_NCPUS=2
-CONFIG_RAMLOG=y
-CONFIG_RAMLOG_SYSLOG=y
-CONFIG_RAMLOG_BUFSIZE=16384
-CONFIG_RAMLOG_NONBLOCKING=y
-CONFIG_RAMLOG_NPOLLWAITERS=4
I would also disable debug output from CPU0 so that I could better see the
debug output from CPU1. In drivers/syslog/vsyslog.c:
+if (up_cpu_index() == 0) return 17; // REMOVE ME
2016-11-26: With regard to SMP, the major issue is cache coherency. I added
some special build logic to move spinlock data into the separate, non-
cached section. That gives an improvement in performance but there are
still hangs. These, I have determined, are to other kinds of cache
coherency problems. Semaphores, message queues, etc. basically all
shared data must be made coherent.
I also added some SCU controls that should enable cache consistency for SMP
CPUs, but I don't think I have that working right yet. See the SMP section
below for more information.
2016-11-28: SMP is unusable until the SCU cache coherency logic is fixed.
I do not know how to do that now.
2016-12-01: I committed a completely untested SPI driver. This was taken
directly from the i.MX1 and is most certainly not ready for use yet.
2016-12-07: Just a note to remind myself. The PL310 L2 cache has *not*
yet been enabled.
2018-02-06: Revisited SMP to see how much has been broken due to bit rot.
Several fixes were needed mostly due to: (1) The new version of
this_task() that calls sched_lock() and sched_unlock(), and (2) to
deferred setting g_cpu_irqlock(). That latter setting is now deferred
until nxsched_resume_scheduler() runs. These commits were made:
commit 50ab5d638a37b539775d1e60085f182bf26be57f
sched/task: It is not appropriate for logic in nxtask_exit() to call
the new version of this_task(). sched/irq: Remove redundant fetch
of CPU index; boards/sabre-lite: update README.
commit 0ba78530164814360eb09ed9805137b934c6f03b
sched/irq: Fix a infinite recursion problem that a recent change
introduced into the i.MX6 SMP implementation.
commit 8aa15385060bf705bbca2c22a5682128740e55a8
arch/arm/src/armv7-a: Found some additional places were the new
this_task() function cannot be called in the i.MX6 SMP configuration.
commit de34b4523fc33c6f2f20619349af8fa081a3bfcd
sched/ and arch/arm/src/armv7-a: Replace a few more occurrences
of this_task() with current_task(cpu) in an effort to get the i.MX6
working in SMP mode again. It does not yet work, sadly.
commit cce21bef3292a40dcd97b6176ea016e2b559de8b
sched/sched: sched_lock() and sched_unlock().. back out some changes
I made recently. The seemed correct but apparently not. Also
reorder to logic so that g_global_lockcount is incremented for the very
minimum amount of time.
With these changes, basic SMP functionality is restored and there are no
known issues (Configuration 'smp' with 4 CPUs and data cache disabled).
It is possible, however, that additional changes similar to the above will
be required in other areas of the OS, but none such are known as of this
writing. Insufficient stress testing has been done to prove that the
solution is stable.
2018-06-08: Again revisited SMP. There appears to be a memory corruption problem.
This is rarely seen with the SMP test but you enable the OS test in the smp
configuration, you will see a crash due to memory corruption consistently,
specially in the nested signal test (apps/examples/ostest/signest.c).
2018-06-20: There was a problem with the Interrupt Stack for SMP in
arch/arm/src/armv7-a/arm_vectors.S: There is only one interrupt stack for
all CPUs! A fix for this was put in place on 2018-06-21. Big Improvement!
But this does not completely eliminate instabilities which seem to be
related to memory corruption -- mm_mallinfo() asserts.

Serial Console
==============
A DEBUG VCOM is available MICRO USB AB 5 J509. This corresponds to UART1
from the i.MX6. UART1 connects to J509 via the CSIO_DAT10 and CSIO_DAT11
pins
LEDs and Buttons
================
LEDs
----
A single LED is available driven GPIO1_IO02. On the schematic this is
USR_DEF_RED_LED signal to pin T1 (GPIO_2). This signal is shared with
KEY_ROW6 (ALT2). A high value illuminates the LED.
This LED is not used by the board port unless CONFIG_ARCH_LEDS is
defined. In that case, the usage by the board port is defined in
include/board.h and src/sam_autoleds.c. The LED is used to encode
OS-related events as follows:
------------------- ----------------------- ------
SYMBOL Meaning LED
------------------- ----------------------- ------
LED_STARTED NuttX has been started OFF
LED_HEAPALLOCATE Heap has been allocated OFF
LED_IRQSENABLED Interrupts enabled OFF
LED_STACKCREATED Idle stack created ON
LED_INIRQ In an interrupt N/C
LED_SIGNAL In a signal handler N/C
LED_ASSERTION An assertion failed N/C
LED_PANIC The system has crashed FLASH
Thus if the LED is statically on, NuttX has successfully booted and is,
apparently, running normally. If the LED is flashing at approximately
2Hz, then a fatal error has been detected and the system has halted.
Buttons

Using U-Boot to Run NuttX
=========================
The MCIMX6Q-SDB comes with a 8GB SD card containing the U-Boot and Android.
You simply put the SD card in the SD card slot SD3 (on the bottom of the
board next to the HDMI connect) and Android 4.2.2.1 will boot.
But we need some other way to boot NuttX. Here are some things that I have
experimented with.
Building U-Boot (Failed Attempt #1)
-----------------------------------
I have been unsuccessful getting building a working version of u-boot from
scratch. It builds, but it does not run. Here are the things I did:
1. Get a copy of the u-boot i.MX6 code and Android GCC toolchain
$ git clone https://source.codeaurora.org/external/imx/uboot-imx.git -b nxp/imx_v2009.08
$ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6
2. Build U-Boot for the i.MX6Q Sabre using the following steps. This
assumes that you have the path to the above toolchain at the
beginning of your PATH variable:
$ cd uboot-imx
$ export ARCH=arm
$ export CROSS_COMPILE=arm-eabi-
$ make mx6q_sabresd_android_config
$ make
This should create a number of files, including u-boot.bin
3. Format an SD card
Create a FAT16 partition at an offset of about 1MB into the SD card.
This is where we will put nuttx.bin.
4. Put U-Boot on SD.
$ dd if=u-boot.bin of=/dev/<your-sd-card> bs=1k
$ sync
Your SD card device is typically something in /dev/sd<X> or
/dev/mmcblk<X>. Note that you need write permissions on the SD card
for the command to succeed, so you might need to su - as root, or use
sudo, or do a chmod a+w as root on the SD card device node to grant
permissions to users.
Using the Other SD Card Slot (Failed Attempt #2)
------------------------------------------------
Another option is to use the version u-boot that came on the 8GB but put
NuttX on another SD card inserted in the other SD card slot at the opposite
corner of the board.
To make a long story short: This doesn't work. As far as I can tell,
U-Boot does not support any other other SC card except for mmc 2 with is the
boot SD card slot.
Replace Boot SD Card (Successful Attempt #3)
--------------------------------------------
What if you remove the SD card after U-boot has booted, then then insert
another SD card containing the nuttx.bin image?
1. Build nuttx.bin and copy it only a FAT formatted SD card. Insert the SD
card containing NuttX into the "other" SD card slot. Insert the 8GB SD
card with U-boot already on it in the normal, boot SD card slot.
2. Connect the VCOM port using the USB port next to the boot SD card slot.
3. Start a console at 11500 8N1 on the VCOM port
4. Power up the board with the 8GB SD card in place. U-Boot will start and
countdown before starting Linux. Press enter to break into U-Boot before
Linux is started.
5. Remove the 8GB U-Boot SD card; insert in its place.
6. Rescan the SD card:
MX6Q SABRESD U-Boot > mmc dev 2
mmc2 is current device
MX6Q SABRESD U-Boot > mmc rescan
MX6Q SABRESD U-Boot > fatls mmc 2
system volume information/
87260 nuttx.bin
1 file(s), 1 dir(s)
7. Then we can boot NuttX off the rescanned SD card:
MX6Q SABRESD U-Boot > fatload mmc 2 0x10800000 nuttx.bin
reading nuttx.bin
87260 bytes read
MX6Q SABRESD U-Boot > go 0x10800040
## Starting application at 0x10800040 ...
That seems to work okay.
Use the FAT Partition on the 8GB SD Card (Untested Idea #4)
-----------------------------------------------------------
Partition 4 on the SD card is an Android FAT file system. So one thing you
could do would be put the nuttx.bin file on that partition, then boot like:
MX6Q SABRESD U-Boot > fatload mmc 2:4 0x10800000 nuttx.bin
SD Card Image Copy (Successful Attempt #5)
------------------------------------------
You can use the 'dd' command to copy the first couple of megabytes from the
8GB SD card and copy that to another SD card. You then have to use 'fdisk'
to fix the partition table and to add a single FAT16 partition at an offset
of 1MB or so.
1. Insert the 8GB boot SD card into your PC: Copy the first 2Mb from the SD
card to a file:
$ dd if=/dev/sdh of=sdh.img bs=512 count=4096
2. Remove the 8GB boot SD card and replace it with a fresh SD card. Copy the
saved file to the first the new SD card:
$ dd of=/dev/sdh if=sdh.img bs=512 count=4096
3. Then use 'fdisk' to:
- Remove all of the non-existent partitions created by the 'dd' copy.
- Make a single FAT16 partition at the end of the SD card.
You will also need to format the partion for FAT.
4. You can put nuttx.bin here and then boot very simply with:
MX6Q SABRESD U-Boot > fatload mmc 2:1 0x10800000 nuttx.bin
MX6Q SABRESD U-Boot > go 0x10800040
A little hokey, but not such a bad solution.
TFTPBOOT (Successful Attempt #6)
------------------------------------------
If you can prepare tftp server, this approach would be easy
1. Copy nuttx.bin to the tftp server (e.g. /var/lib/tftpboot/ )
2. Load nuttx.bin from the server and boot
MX6Q SABRESD U-Boot > setenv ipaddr 192.168.10.103
MX6Q SABRESD U-Boot > setenv serverip 192.168.10.16
MX6Q SABRESD U-Boot > setenv image nuttx.bin
MX6Q SABRESD U-Boot > tftp ${loadaddr} ${image}
PHY indentify @ 0x1 = 0x004dd074
FEC: Link is Up 796d
Using FEC0 device
TFTP from server 192.168.10.16; our IP address is 192.168.10.103
Filename 'nuttx.bin'.
Load address: 0x10800000
Loading: ###############
done
Bytes transferred = 217856 (35300 hex)
MX6Q SABRESD U-Boot > go ${loadaddr}
## Starting application at 0x10800000 ...

Debugging with the Segger J-Link
================================
These procedures work for debugging the boot-up sequence when there is a
single CPU running and not much else going on. If you want to do higher
level debugger, you will need something more capable. NXP/Freescale suggest
some other debuggers that you might want to consider.
These instructions all assume that you have built NuttX with debug symbols
enabled. When debugging the nuttx.bin file on the SD card, it is also
assumed the nuttx ELF file with the debug symbol addresses is from the
same build so that the symbols match up.
Debugging the NuttX image on the SD card
----------------------------------------
1. Connect the J-Link to the 20-pin JTAG connector.
2. Connect the "USB TO UART" USB VCOM port to the host PC. Start a
terminal emulation program like TeraTerm on Minicom. Select the USB
VCOM serial port at 115200 8N1.
When you apply power to the board, you should see the U-Boot messages in
the terminal window. Stop the U-Boot countdown to get to the U-Boot
prompt.
3. Start the Segger GDB server:
Target: MCIMX6Q6
Target Interface: JTAG
If the GDB server starts correctly you should see the following in the
Log output:
Waiting for GDB Connection
4. In another Xterm terminal window, start arm-none-eabi-gdb and connect to
the GDB server.
From the Xterm Window:
$ arm-none-eabi-gdb
You will need to have the path to the arm-none-eabi-gdb program in your
PATH variable.
Then from GDB:
gdb> target connect localhost:2331
gdb> mon halt
5. Start U-boot under GDB control:
From GDB:
gdb> mon reset
gdb> mon go
Again stop the U-Boot countdown to get to the U-Boot prompt.
6. Load NuttX from the SD card into RAM
From U-Boot:
MX6Q SABRESD U-Boot > fatload mmc 2:1 0x10800000 nuttx.bin
7. Load symbols and set a breakpoint
From GDB:
gdb> mon halt
gdb> file nuttx
gdb> b __start
gdb> c
__start is the entry point into the NuttX binary at 0x10800040. You can,
of course, use a different symbol if you want to start debugging later
in the boot sequence.
8. Start NuttX
From U-Boot:
MX6Q SABRESD U-Boot > go 0x10800040
9. You should hit the breakpoint that you set above and be off and
debugging.
Debugging a Different NuttX Image
---------------------------------
Q: What if I want do run a different version of nuttx than the nuttx.bin
file on the SD card. I just want to build and debug without futzing with
the SD card. Can I do that?
A: Yes with the following modifications to the procedure above.
- Follow steps 1-5, i.e.,
1. Connect the J-Link to the 20-pin JTAG connector.
2. Connect the "USB TO UART" USB VCOM port to the host PC and start a
terminal emulation program.
3. Start the Segger GDB server.
4. Start arm-none-eabi-gdb and connect to the GDB server.
5. Start U-boot under GDB control, stopping the countdown to get
the U-boot prompt.
- Skip step 6, don't bother to load NuttX into RAM
- In step 7, load NuttX into RAM like this:
gdb> mon halt
gdb> load nuttx <-- Loads NuttX into RAM at 0x010800000
gdb> file nuttx
gdb> b __start
gdb> c
- Then after step 7, you should hit the breakpoint at the instruction you
just loaded at address 0x10800040.
- Or, in step 6, instead of continuing ('c') which will resume U-Boot,
even just:
gdb> mon halt
gdb> load nuttx <-- Loads NuttX into RAM at 0x010800000
gdb> file nuttx
gdb> mon reg pc 0x10800040
gdb> s
The final single will then step into the freshly loaded program.
You can then forget about steps 8 and 9.
This is, in fact, my preferred way to debug.
NOTE: Setting the PC to 0x10800040 is a superstituous step. The PC
will be set 0x10800040 by the 'load nuttx' command.
You can restart the debug session at any time at the gdb> prompt by:
gdb> mon reset
gdb> mon go
That will restart U-Boot and you have to press ENTER in the terminal
window to stop U-Boot. Restarting U-Boot is a necessary part of the
restart process because you need to put the hardware back in its initial
state before running NuttX.
Then this will restart the debug session just as before:
gdb> mon halt
gdb> load nuttx <-- Loads NuttX into RAM at 0x010800000
gdb> file nuttx
gdb> mon reg pc 0x10800040
gdb> s
Debugging with QEMU
================================
The nuttx ELF image can be debugged with QEMU.
1. To debug the nuttx (ELF) with symbols, following change must
be applied to defconfig.
diff --git a/boards/arm/imx6/sabre-lite/configs/nsh/defconfig b/boards/arm/imx6/sabre-lite/configs/nsh/defconfig

2. Please note that QEMU does not report PL310 (L2CC) related

the nuttx will stop with DEBUGASSERT(). To avoid this,
comment out the following lines.

3. Run QEMU
Run qemu with following options, these options do not load nuttx.
Instead, just stops the emulated CPU like "reset halt" with OpenOCD.
$ qemu-system-arm -M sabrelite -smp 4 -nographic -s -S
NOTE: -smp 4 option should be used for both nsh configuration
(non-SMP) and smp configuration (regardless of CONFIG_SMP_NCPUS)
To quit QEMU, type Ctrl-A + X
3. Run gdb, connect to QEMU, load nuttx and continue

SMP
===
The i.MX6 6Quad has 4 CPUs. Support is included for testing an SMP
configuration. That configuration is still not yet ready for usage but can
be enabled with the following configuration settings:
RTOS Features -> Tasks and Scheduling
CONFIG_SPINLOCK=y
CONFIG_SMP=y
CONFIG_SMP_NCPUS=4
Open Issues:
1. Currently all device interrupts are handled on CPU0 only. Critical sections will
attempt to disable interrupts but will now disable interrupts only on the current
CPU (which may not be CPU0). There is a spinlock to prohibit entrance into these
critical sections in interrupt handlers of other CPUs.
When the critical section is used to lock a resource that is also used by
interrupt handling, the interrupt handling logic must also take the spinlock.
This will cause the interrupt handlers on other CPUs to spin until
leave_critical_section() is called. More verification is needed.
2. Recent redesigns to SMP of another ARMv7-M platform have made changes to the OS
SMP support. There are no known problem but the changes have not been verified
fully (see STATUS above for 2019-02-06).
Configurations
==============
Information Common to All Configurations
----------------------------------------
Each Sabre-Lite configuration is maintained in a sub-directory and
can be selected as follow:
tools/configure.sh sabre-lite:<subdir>
Before building, make sure the PATH environment variable includes the
correct path to the directory than holds your toolchain binaries.
And then build NuttX by simply typing the following. At the conclusion of
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
make oldconfig
make
The <subdir> that is provided above as an argument to the tools/configure.sh
must be is one of the following.
NOTES:
1. These configurations use the mconf-based configuration tool. To
change any of these configurations using that tool, you should:
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
see additional README.txt files in the NuttX tools repository.
b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
2. Unless stated otherwise, all configurations generate console
output on UART1 which is a available to the host PC from the USB
micro AB as a VCOM part.
3. All of these configurations are set up to build under Windows using the
"GNU Tools for ARM Embedded Processors" that is maintained by ARM
(unless stated otherwise in the description of the configuration).
https://developer.arm.com/open-source/gnu-toolchain/gnu-rm
That toolchain selection can easily be reconfigured using
'make menuconfig'. Here are the relevant current settings:
Build Setup:
CONFIG_HOST_WINDOWS=y : Window environment
CONFIG_WINDOWS_CYGWIN=y : Cywin under Windows
System Type -> Toolchain:
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : GNU ARM EABI toolchain
Configuration sub-directories
-----------------------------
nsh
---
This is a NuttShell (NSH) configuration that uses the NSH library
at apps/nshlib with the start logic at apps/examples/nsh.
NOTES:
1. This configuration assumes that we are loaded into SDRAM and
started via U-Boot.
2. The serial console is configured by default for use UART1, the
USB VCOM port (UART1), same as the serial port used by U-Boot.
You will need to reconfigure if you want to use a different UART.
3. NSH built-in applications are supported, but no built-in
applications are enabled.
Binary Formats:
CONFIG_BUILTIN=y : Enable support for built-in programs
Application Configuration:
CONFIG_NSH_BUILTIN_APPS=y : Enable starting apps from NSH command line
4. The RAMLOG is enabled. All SYSLOG (DEBUG) output will go to the
RAMLOG and will not be visible unless you use the nsh 'dmesg'
command. To disable this RAMLOG feature, disable the following:
Device Drivers: CONFIG_RAMLOG
smp
---
This is a configuration of testing the SMP configuration. It is
essentially equivalent to the nsh configuration except has SMP enabled
and supports apps/testing/smp.
Sample output of the SMP test is show below (Configuration all 4 CPUs
but with data cache disabled):

NOTES:
1. See the notes for the nsh configuration. Since this configuration
is essentially the same all of those comments apply.
2. See the STATUS and SMP sections above for detailed SMP-related
issues. There are a some major problems with the current SMP
implementation.

* Name: board_app_initialize
*
* Description:
* Perform application specific initialization. This function is never
* called directly from application code, but only indirectly via the
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
*
* Input Parameters:
* arg - The boardctl() argument is passed to the board_app_initialize()
* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initialization logic and the
* matching application logic. The value could be such things as a
* mode enumeration value, a set of DIP switch switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.

/* LEDs
*
* A single LED is available driven by USR_DEF_RED_LED.
*
* These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
* defined. In that case, the usage by the board port is defined in
* include/board.h and src/imx_autoleds.c. The LEDs are used to encode
* OS-related events as follows:
*
* ------------------- ----------------------- ------
* SYMBOL Meaning LED
* ------------------- ----------------------- ------
* LED_STARTED NuttX has been started OFF
* LED_HEAPALLOCATE Heap has been allocated OFF
* LED_IRQSENABLED Interrupts enabled OFF
* LED_STACKCREATED Idle stack created ON
* LED_INIRQ In an interrupt N/C
* LED_SIGNAL In a signal handler N/C
* LED_ASSERTION An assertion failed N/C
* LED_PANIC The system has crashed FLASH
*
* Thus is LED is statically on, NuttX has successfully booted and is,
* apparently, running normally. If LED is flashing at approximately
* 2Hz, then a fatal error has been detected and the system has halted.
