I couldn't get sdcard boot to work yet. Are there any settings regarding that or did it work pretty much out of the box on your other boards?

Also which sequence of commands did you use to check sdcard support in busybox?

Does sdcard boot work with e.g. vexriscv? I think the gateware is pretty much ready to work out of the box, but depending on CSR access, DMA, and other various "moving parts", there may be something about ulx3s that's somehow different.

Also which sequence of commands did you use to check sdcard support in busybox?

If the proper DTS entry is found, the kernel will initialize it (instead of where you have all those cmd8/cmd55 failures in your boot log above). You can then mount /dev/mmcblk0p1 and things should be fairly straightforward from there.
