Yocto build error

[adrianalin]

Trying to build an image with bitbake core-image-base (using docker because I don't have Ubuntu) but get following errors:

$ bitbake core-image-base

This is a known issue:

https://lists.yoctoproject.org/g/yocto/topic/98824124#60005

Right now only the BSP and basic initramfs are building.

This requires external uclibc toolchains to work properly with cortex m7

Managed to build the fitimage with kas-container, flashed, and when booting I get (maybe because of missing initramfs):
