Please find my .config attached

I also tried with your toolchain but still the same issue, see the log attached (with initcall_debug in bootargs).
Then i used an another rootfs (attached rootfs_mcu.cpio file) but unfortunately, during the
rootfs init, some memory allocation are done and failed due to low RAM available on this board.
The issue seems linked to the rootfs...but i got no clue on what is going wrong with your rootfs ?
Thanks
