imx8mn configuration fragments not applied

Hi there,

I try to implement a kernel configuration in yocto for imx8m nano evaluation kit.


Following steps of

Yocto Project Linux Kernel Development Manual 

5.6.2. Creating Configuration Fragments


I put a .cfg file in my own layer under recipes-kernel/linux/files

with content



and called it in linux-imx_5.4.bbappend


FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

SRC_URI += "file://bcm2835.cfg"


but in my work directory under linux-imx/5.4-r0/

it does neither appear in defconfig nor /build/.config

In build/.config there is

# CONFIG_ARCH_BCM2835 is not set


This happens to all configurations that I tried to make.

Is there anything I forgot to do?


Best regards,
