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.

core-image-minimal-beaglev-starlight-jh7100.wic.gzonto uSD card:
$ sudo bmaptool copy --bmap core-image-minimal-beaglev-starlight-jh7100.wic.bmap core-image-minimal-beaglev-starlight-jh7100.wic.gz /dev/sdx
- Flash U-Boot:
$ perl -e 'print pack("l", (stat @ARGV[0])[7])' fw_payload.bin > fw_payload.bin.out
$ cat fw_payload.bin >> fw_payload.bin.out
- Interrupt the boot process and send the
fw_payload.bin.out. Details can be found here
Testing
-
The root partition is sometimes not found on time -
rootdelay=3parameter was added to the cmdline -
The booting fails in following way currently:
