The bs=1m in the first dd line, fails for me after a while on my desktop, so I can't use it, and have to use the default block size. the other two dd lines have bs=512 but that's the default, so could be omitted, and I ran sync just at the very end. So I think my prepared SD card should be fine, at least it boots on the other Rock64 I have, as well as the SD card with installed OpenBSD from the other Rock64 has the same issue on this non-booting device. > > > the device itself boots the u-boot-erase-spi-rock64.img from > > ayufan-rock64/linux-u-boot > > > > Normally u-boot-erase-spi-rock64.img from ayufan is used to erase(delete) the > onboard-SPI-flash , > not to boot from.

The erase did finish properly, and afterwards it boots the NetBSD image, as well as the other SD card from the other Rock64 without issues. cheers, Sebastian > > Regards > > Klaus >
