I just saw advice from martinayotte Posted May 23, 2020 "Rockchip SoCs always have eMMC as boot priority. So, to boot from SDCard, you need to stop U-Boot from eMMC by pressing <spacebar> several times during startup. Then, at U-Boot command line, you can type "setenv devnum 1" followed with "run mmc_boot", it will then boot from SD." I've made a note of this for myself as well, cheers

Hi, have you sorted this out? If not, I suggest that you reload the original downloaded os or a fresh copy back to the reformatted microSD card. Also note advice re the SD quality written elsewhere on this forum. That should give you access to the system. Then you can review your procedures for setting up the NVME and boot options and try again.
