2. Build and install qemu
$ git clone https://github.com/qemu/qemu
$ cd qemu
$ ./configure --target-list=riscv64-softmmu
$ make
$ sudo make install

$ make V=1
5. Run the nuttx with qemu
$ qemu-system-riscv64 -nographic -machine sifive_u -bios ./nuttx
NOTE: To run nuttx for kostest, gdb needs to be used to load both nuttx_user.elf and nuttx
$ qemu-system-riscv64 -nographic -machine sifive_u -s -S
$ riscv64-unknown-elf-gdb -ex 'target extended-remot:1234' -ex 'load nuttx_user.elf' -ex 'load nuttx' -ex 'c'
6. TODO
Support FPU
Support RISC-V User mode

(gdb) load nuttx
(gdb) c
5. Write nuttx.bin to SPI-Flash
$ pip3 install kflash
$ kflash -p /dev/ttyUSB0 -b 1500000 ./nuttx/nuttx.bin
NOTE: The kflash_gui is not recommended because it's unstable
6. TODO
Support peripherals such as GPIO/SPI/I2C/...
Support FPU
Support RISC-V U-mode including memory protection

* 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.
