Hi!

 

Armbian_21.08.1_Orangepiprime_focal_current_5.10.60_xfce_desktop sometime failed to boot. No green indicator, and black screen.

 

Tried to decrease CPU max frequency

sudo nano /etc/default/cpufrequtils
###
ENABLE=true
MIN_SPEED=480000
MAX_SPEED=1200000
GOVERNOR=ondemand
###

 

but still failed to boot sometimes.

 

Armbian_5.75_Orangepiprime_Debian_stretch_next_4.19.20_desktop have been installed before and boot fine during 2 years.

Hard to tell if it is not persistent. If you can hook up a serial console and try to catch the output from a failed boot attempt. Also set verbosity to 7 in armbianEnv.txt. Check our documentation for more details.

Thank you. Currently I don't have a serial console but possible I'll try to get it.

I suspect that it is a problem of CPU settings, because old kernel had maximum 1.1 GHz and had no problems with booting.

Would you please tell me, is the /etc/default/cpufrequtils settings relied to boot, or I should try to change cpufreq-dt driver?

You can always give it a try. If you still have the old image you could compare the opp table of the old and new dts to check if there are differences.

Now I can say for sure that the problem begins with 21.08.

Armbian_21.05.1_Orangepiprime_focal_current_5.10.34_xfce_desktop boots up fine, 40+ tests of booting.

 

OPP and other content of DTS are not the cause of the problem, I have tested it.

Also I have tried another available kernels with 21.08 (5.4, 5.13, etc) and the same problem of boot stability was occurring.

Also I have tried to flash 21.08 into another SD card, the same problem was occurred.

 

It would be good if anyone identify the difference between 21.05.1 and 21.08 that causes the unstable booting.

Important note: it seemed to me that the problem with 21.08 occurs more often on a warm board.
