Hmm.. With DIP switches set to “SDIO” mode, VisionFive2 SBC gives the most informative error message ever:

BOOT fail,Error is 0xffffffff

I’d guess the last value is -1 in 1’s complement format but other than that 🤷

I used #BuildRoot and visionfive2_defconfig. Not sure how feature complete so maybe I will try the official SDK for comparison.

Comparing now how SDIO boot works with the official SDK. I don’t know where “SDIO” comes from but it should boot all from SD and it is the term used in the quick start guide.

The same guide does not give whole a lot of promised as it just states that:

StarFive recommends that you use 1-bit QSPI Nor Flash mode since there is a low possibility that the VisionFive 2 may fail to boot in eMMC or SDIO3.0 boot mode. Try restarting the VisionFive 2 if fails to boot in eMMC or SDIO3.0 boot mode

Probably something like BeagleV would more convenient but it was not yet even publicly announced when I ordered this. And even if I probably eventually get it having multiple pieces for hardware is nice for comparison.
