Creating a bootable disk
|
||||
========================
|
||||
|
||||
This build supports multiboot2, which means that usual multiboot2 bootlaoders, e.g. grub can be used.
|
||||
To create a bootable disk with grub2, create a directory named `iso` with grub configuration file and the compiled nuttx.elf.
|
||||
|
||||
##### Directory and file hierarchy
|
||||
```
|
||||
- iso/
|
||||
- boot/
|
||||
- grub/
|
||||
- grub.cfg
|
||||
- nuttx.elf
|
||||
```
|
||||
|
||||
##### grub.cfg
|
||||
|
||||
The grub.cfg should contain the boot entry of NuttX.
|
||||
```
|
||||
set timeout=0
|
||||
set default=0
|
||||
menuentry "kernel" {
|
||||
multiboot2 /boot/nuttx.elf
|
||||
}
|
||||
```
|
||||
|
||||
##### Making the disk
|
||||
|
||||
Use the following command to create the disk.
|
||||
P.S. In some distros, `grub-mkrescue` is called `grub2-mkrescue`
|
||||
```
|
||||
grub-mkrescue -o boot.iso iso
|
||||
```
|
||||
|
||||
|
||||
QEMU/KVM
|
||||
====
|
||||
|
||||
QEMU is a generic and open source machine emulator and virtual machine. Here are
|
||||
some links (which will probably be mostly outdated by the time your read this):
|
||||
|
||||
Home Page: http://wiki.qemu.org/Main_Page
|
||||
Downloads: http://wiki.qemu.org/Download
|
||||
Documentation: http://wiki.qemu.org/Manual
|
||||
|
||||
KVM is the Linux kernel hypervisor.
|
||||
It supports creations of virtual machines in Linux systems.
|
||||
It is usually coupled with Qemu as its I/O supporting layer.
|
||||
|
||||
The qemu can be build from source or downloaded from distro repositories.
|
||||
However, a modern CPU and KVM support are mandatory because the X2APIC is not available
|
||||
in pure emulator mode.
|
||||
This mean using this build with qemu in windows or old x86 machine can be frustrating.
|
||||
In such case, looks the next section and use bochs emulator instead.
|
||||
|
||||
Running QEMU
|
||||
------------
|
||||
|
||||
In the top-level NuttX directory:
|
||||
|
||||
qemu-system-x86_64 -cpu host -enable-kvm -m 2G -cdrom boot.iso -nographic -serial mon:stdio
|
||||
|
||||
This multiplex the qemu console and COM1 to your console.
|
||||
Use control-a 1 and 2 to switch between.
|
||||
Use control-a x to terminate the emulation.
|
||||
|
||||
P.S. Make sure that you CPU supports the mandatory features. Look at Real machine
|
||||
section for more information.
|
||||
|
||||
Bochs
|
||||
=====
|
||||
|
||||
Bochs is also a generic and open source machine emulator and virtualizer.
|
||||
It does very comprehensive emulation of x86 platform, even the state-of-art processors.
|
||||
Here are some links (which will probably be mostly outdated by the time your read this):
|
||||
|
||||
Home Page: http://bochs.sourceforge.net
|
||||
|
||||
The bochs can be build from source.
|
||||
Unlike qemu, it do not rely on KVM to support modern hardware features, therefor it can
|
||||
also be used under windows.
|
||||
When building bochs, remember to enable x86-64 support with "--enable-x86-64".
|
||||
If you also want the support of SIMD instruction, enable them with "--enable-avx --enable-evex".
|
||||
|
||||
Running Bochs
|
||||
------------
|
||||
|
||||
First edit/check the .bochsrc
|
||||
You can create one in the top-level NuttX directory or bochs will use the one in your $HOME.
|
||||
Remember to change the CPU model to one with mandatory features and enable the COM port.
|
||||
|
||||
* Find and edit (You might adjust the IPS as you machine perform):
|
||||
```
|
||||
cpu: model=broadwell_ult, count=1, ips=50000000, reset_on_triple_fault=0, ignore_bad_msrs=0, msrs="msrs.def" a
|
||||
ata0-master: type=cdrom, path="<PATH TO boot.iso>", status=inserted
|
||||
|
||||
```
|
||||
|
||||
* Add:
|
||||
```
|
||||
com1: enabled=1, mode=file, dev=com1.out
|
||||
```
|
||||
|
||||
In the top-level NuttX directory:
|
||||
|
||||
```
|
||||
bochs
|
||||
```
|
||||
|
||||
The emulator will drop into debugger mode.
|
||||
Enter 'c' to start the emulation.
|
||||
COM port output will be in the com1.out file.
|
||||
|
||||
|
||||
Real machine
|
||||
============
|
||||
|
||||
This port should work on real x86-64 machine with a proper CPU.
|
||||
The mandatory CPU features are:
|
||||
* TSC DEADLINE or APIC timer
|
||||
* PCID
|
||||
* X2APIC
|
||||
|
||||
WARNING: IF you use TSC DEADLINE, make sure that your CPU's TSC DEADLINE timer is not buggy!
|
||||
|
||||
Toolchains
|
||||
==========
|
||||
|
||||
Currently, only the Linux GCC toolchain is tested.
|
||||
While building on a modern x86_64 PC, the default system GCC can be used.
|
||||
|
||||
Configurations
|
||||
==============
|
||||
|
||||
Common Configuration Notes
|
||||
--------------------------
|
||||
|
||||
1. Each Qemu-intel64 configuration is maintained in a sub-directory
|
||||
and can be selected as follow:
|
||||
|
||||
tools/configure.sh qemu-intel64:<subdir>
|
||||
|
||||
Where <subdir> is one of the configuration sub-directories described in
|
||||
the following paragraph.
|
||||
|
||||
2. These configurations use the mconf-based configuration tool. To
|
||||
change a 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.
|
||||
|
||||
3. By default, all configurations assume the Linux. This is easily
|
||||
reconfigured:
|
||||
|
||||
CONFIG_HOST_LINUX=y

||||

* (non-standard) boardctl() interface using the command BOARDIOC_INIT.

*
|

|
||||
* 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.
