[Banana Pi M64 kernel error]

Reading up on other topics like:

and

and

I was wondering if maybe the default configuration for the A64 start it with a borderline high frequency. depending on the board quality it works, for others not. Combined with the fact that temperature readings seem not to work properly and as such thermal throttling not working, the system is running into a kernel panic.

I furtehr noticed that the CPU is getting warmer then when using it with the Debian 4.4 image.

 

To test this, I would like to startup the kernel with a lower frequency. Normally - if I understand correctly I would change the CPU frequency in /etc/default/cpufrequtils - but is there a way to set this on uboot?

 

 

 

 

 

 

[Banana Pi M64 kernel error]

Hi I got my BPI-M64 board V1.1 up and running using the Debian 4.4 image, however I am not able to use Armbian.

 

I tried several SD cards, and checked the power supply delivering enough juice for the board (among others I monitor the volatage on the 3.3V and 5V pins of the GPIO Pin header).

 

For example using the Armbian_5.90_Bananapim64_Debian_buster_next_4.19.57.img with mainline kernel from https://www.armbian.com/bananapi-m64/

It starts up into u-boot fine:

the boot.env error I solved via

## Resetting default environment

but will still fail later with a kernel panic around

What can I do to get to the root of this issue and fix it?
