Test SDCard boot with OrangeCrab
See original GitHub issueI just added SDCard SPI-Mode support to the OrangeCrab with: https://github.com/litex-hub/litex-boards/commit/6e6b6dac5524e2b9ebef0d3d1be316674a7bd012 and https://github.com/litex-hub/linux-on-litex-vexriscv/commit/dc61f0acf95506b08e8486e33590ff9ddf8b3095 but don’t have the harware to test it.
@pdp7, @gregdavill interested in testing? 😃
If so, you can use the attached bitstream and copy the attached images to a FAT16 formated SDCard.
Then just try to boot with spisdcardboot command. (that’s possible you’ll have to type it twice since the SDCard does not always seem to be initialized correctly the first time).

@pdp7: you should be able to build it with upstream repos. ValentyUSB is automatically cloned when building the OrangeCrab bitstream: https://github.com/litex-hub/linux-on-litex-vexriscv/blob/master/make.py#L221.
The code has been refactored (to use FatFs and allow FAT16/FAT32 partitions), performance has been improved (>1MB/s transfers) and has been tested recently on the OrangeCrab: https://twitter.com/enjoy_digital/status/1271128930385362947
A new wiki page that explains the different boot options is also available at: https://github.com/enjoy-digital/litex/wiki/Load-Application-Code-To-CPU
