Oh that's great. So it should be possible do something like this to extract u-boot from the linux image and write to uSD: dd if=rk3328-sd-friendlycore-bionic-5.4-arm64-20200312.img \ of=nanopi.r2s.u-boot.img skip=64 count=32000 dd if=miniroot66.fs of=/dev/sdXc bs=1m dd if=nanopi.r2s.u-boot.img of=/dev/sdXc seek=64 where sdX is the micro sd being prepared and miniroot66.fs is from current. > > > > I don't see support for the NanoPi R2S in u-boot master so there's > > a decent amount of work to add support for it.
