mk-kernel.sh fails

[hpsaturn]

Summary

I have an error trying to follow your steps, but first I have one doubt with this file:

arm-buildroot-linux-gnueabihf_sdk-buildroot250531.tar.gz

it never is used in your steps. I wondering how you uses it?

error details

error details

arm-buildroot-linux-gnueabihf_sdk-buildroot250531.tar.gz is SDK to build APP. You don't need it when build image.

[hpsaturn]

Ok thanks. I wasn't using it, was only curious. But what about this error? Maybe do you know? Thanks.

I think, that maybe this is not the problem, because I found that the problem is more up:

I think that this problem is better explained and fixed here, in this fork of this repo:
