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. 1 Quote Link to comment Share on other sites More sharing options...
0 le51 Posted May 23, 2020 Share Posted May 23, 2020 thank you @martinayotte for the tip. @orangepower : as you, I was in such a trouble: my solution was to remove emmc module from the nanoPi and then from my PC erase emmc's content using an usb2emmc adapter. Kind of brutal solution but really efficient 0 Quote Link to comment Share on other sites More sharing options...
0 orangepower Posted May 25, 2020 Author Share Posted May 25, 2020 I also bought emmc2microsd but there is a problem with small notch on it. My emmc plug in oposite way and than there is no way you can plug microsd anywhere. After a while I forced it in oposide way and was able to erase emmc with PC. There was no chance to stop booting to go to U-boot. It simply does not work.. But I manage to solve this probem..by force.. 0 Quote Link to comment Share on other sites More sharing options...

0 Lennyz1988 Posted July 23, 2021 Share Posted July 23, 2021 I don't know if this is still relevant. But maybe for future reference. If you remove the EMMC chip, power up the board and after 1 or 2 seconds plug the EMMC module in. That way the board boots from the SDcard and the EMMC chip is still recognized. I was able to manually mount the EMMC chip and/or reflash using armbian-config. 0 Quote Link to comment Share on other sites More sharing options...
0 Guest Posted June 18, 2022 Share Posted June 18, 2022 Flashing Buster on the emmc with my pc with Balenaetcher has always worked well for me. I use the SD card only to do offline emmc image backup...SD card has just Armbian server OS on it for doing this.
