Hi, > Which board did you test? When you do power-on, is it reproduced every time?
I am using Rockchip RK3399 based board - NanoPi R4S for this test. It doesn't appear every time, but it should be encountered once about 20 times. I have run "setenv bootcmd reset; saveenv; reset" for automated testing. > Could you change from your ID to your name? This is my first time sending a patch, sorry I didn't notice this, do I need to resend this patch?
