This kernel version does not match to what is currently present in the
[dufell] branch of community BSP. Current linux-fslc-imx version
included there is actually 5.4.51. Version 5.4.3 looks a rather NXP
"default" kernel to me...

Can you provide a Yocto build header, where it is seeing which layers
are used in your build and at which revisions? This is what you
actually get at the beginning of bitbake execution.


Sure, here you go:

It could be that I didn't flash my sdcard right.  I first tried the NXP release which generates a sdcard image.  Both of the fsl-community-bsp builds I did generated a wic.gz image instead of a sdcard.bz2 image like NXP does.

I simply unzipped the wic.gz image and did a dd to my sdcard.  Hopefully that's the right way to do it and I'm not still booting the original NXP image from my first try.  That would be embarrassing ;)

Brian
