1 flash the latest firmware to the emmc https://drive.google.com/drive/u ... gAqAX2oyZkg2QVQwZjA
the loader is needed.
2 write this firmware to you SDcard https://drive.google.com/drive/u ... gAqAamx6cXd6b205eEk with dd command.
3 insert the card, and reboot the board.

Isle, I can confirm that this image do work to boot up from SD card. Did try everything else before. I was unable to flash the emmc drive through usb-C cable and upgrade_tool. Thanks for this solution. Now the documents for firefly rk3399 are much better. One have to have the ability to boot from SD also if USB flashing is somehow not working. It would be nice to have a jumper on the board.

Hello, I would also like to try this solution because I can not flash any more firmeware. The link you propose is no longer valid, you can give a new one?

Thank you
