BeagleV
|
|
=======
|
|
|
|
BeagleV is a low-cost RISC-V 64-bit based platform. The beta revision of the
|
|
board uses the Starfive JH7100 SoC.
|
|
|
|
How to build
|
|
============
|
|
|
|
```
|
|
$ SHELL=/bin/bash kas-container build ./meta-riscv/beaglev.yml
|
|
```
|
|
|
|
The `kas-container` script can be obtained from
|
|
[kas repository](https://github.com/siemens/kas/blob/2.4/kas-container).
|

Flashing Linux
|
|
==============
|
|
|
|
Flash `core-image-minimal-beaglev-starlight-jh7100.wic.gz` onto uSD card:
|
|
|
|
```
|
|
$ sudo bmaptool copy --bmap core-image-minimal-beaglev-starlight-jh7100.wic.bmap core-image-minimal-beaglev-starlight-jh7100.wic.gz /dev/sdx
|
|
```
|
|
|
|
Flashing U-Boot
|
|
===============
|
|
|
|
Generally you shouldn't need to change u-boot or OpenSBI, but if you do need
|
|
to you can update it with the Xmodem protocol. Below are steps to do this with
|
|
Linux and screen.
|
|
|
|
First prepare the image with
|
|
|
|
```
|
|
$ perl -e 'print pack("l", (stat @ARGV[0])[7])' fw_payload.bin > fw_payload.bin.out
|
|
$ cat fw_payload.bin >> fw_payload.bin.out
|
|
```
|
|
|
|
and install the `lrzsz` package.
|
|
|
|
Then connect to the UART console
|
|
|
|
```shell
|
|
screen /dev/ttyUSB0 115200
|
|
```
|
|
|
|
Press the `RST` button on the board and then press a key to interrupt the
|
|
boot process. You should then see
|
|
|
|
```text
|
|
*************** FLASH PROGRAMMING *****************
|
|
```
|
|
|
|
After that press `0` to update the bootloader. Then press `Ctrl` + `A` then `:`.
|
|
In screen run:
|
|
|
|
```shell
|
|
exec !! sx fw_payload.bin.out
|
|
```
|
|
You can now watch the bootloader update. After it is complete you can reboot the board and watch it boot.
