Device tree overlay - set default board optimizations at boot

[konki]

Hello dear armbianites,

 

I'm trying to make the hc1 optimization for the odroid HC2 board permanent, every time the kernel is updated, armbiam loses the optimization and an admin action is needed to apply the optimization again via ambianconfig > System DTB  > optimized board configuration, followed by a reboot.
My Odroid HC2 suffers from temperature sensor problems, which can be easily bypassed. But I avoid restarts of this server which hosts an OMV instance for personal needs.

 

I understand that the /boot/armbianEnv.txt file passes the information to /boot/boot.ini, but this file seems to be overwritten when the kernel is updated!

is there any possibility of upstream action like 'first.boot' after update?

If possible, please provide diagnostic logs with ...

armbianmonitor -u

... and post the link here.  It'll may help others determine what the issue is.

hi,

 

here is a log before the kernel update: https://paste.armbian.com/xawajuyito

 

the board loses HC1 optimization just after apt-upgrade, here is a log before reboot: https://paste.armbian.com/itocatefak

 

I apply hc1 optimization again via ambianconfig>System DTB >optimized board configuration, before reboot

 

the board crashed during reboot several times before finally booting completely: https://paste.armbian.com/gufozeyedi

/boot/armbianEnv.txt contained 2 lines board_name=hc1 after reboot!

 

This is not my initial question, but it's a problem I've encountered for at least 6-8 months, hardware or software problem?

 

Thanks

Hi,

I ended up by disabling the kernel update (the loaded kernel is Linux 5.4.225-odroidxu4). My odroidhc2 has been running for over 3 months now.

This is a workaround not a solution!

 

Is there a solution to freeze the HC1/HC2 optimization during the kernel update?

Thanks
