Kernel crash

[q2210377]

I tried to create my own image using the build script for Orange Pi Zero. But starting this crashes immediately. Any suggestions?

When you compile your own armbian, it might be helpful to know what you changed compared to a standard armbian..
I'm not an expert there.. but providing as much information as possible makes it easier for others to get an idea whats wrong on your build.

Hi,

the problem seems to be related to kernel compiled with the THUMB2 instructions set enabled.

In you kernel defconfig check if you have the following option enabled.

CONFIG_THUMB2_KERNEL=y

and disable it in case.

This worked for me.

 

BTW: the problem for me started when compiling the kernel using Yocto "rocko" release and it was not present in previous Yocto "pyro" release.
