2. Follow instruction on https://github.com/enjoy-digital/litex to build the vexriscv softcore fpga gateware
|
||||
and flash to arty_a7 board
|

3. Configure and build NuttX

4. Setup tftp server on your laptop, copy nuttx.bin to your tftpboot directory and change its name to boot.bin
|
||||
|
||||
5. Setup the wire connection(uart and tftp) between your board and laptop
|

6. Run $ minicom -b 1000000 /dev/ttyUSB1 (the default baudrate on litex vexriscv is 1e6)
|

when you see the bios prompt "litex>", type "netboot" and enter soon comes the nsh prompt

* Description:

* Perform architecture specific initialization
|
||||
*
|
||||
* 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 cold 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.
