Reboot on ROCK PI N10


I am using ROCK PI N10A with Debian system (
Every time when the ROCK PI is connected to the power, it canot reboot. When I enter the “reboot” command, it is like shutting down, there is no display on the screen, and ssh does not work. Finally I had to press the reset button, and then it can restart normally, but I can’t cut off the power, the problem will recur.
I use SD card to boot the system and I never use eMMC. I think the reason is that sometimes it tries to start from emmc, so it is blocked.

I have tried to erase the eMMC with “dd if=/dev/zero of=./zero.img bs=4M count=100 status=progress &&sync, dd if=./zero.img of=/dev/mmcblk2 bs=4M status=progress&&sync”. But it doesn’t seem to work.

I want to modify the /boot/uEnv.txt to specify to boot from the SD card, but I don’t have any ideas.

Any help is greatly appreciated
