Hi all, I'm trying to get barebox going for a new imx8mp based board. I can successfully power on and get to a barebox prompt etc and fiddle with gpios, files on sd, memtest etc, but when booting to kernel it will hang. Note though that the board boots ok with u-boot (using exact same kernel image). I'm trying to figure out what is different between booting via uboot and barebox, I'm new to imx8 so have been going down a few rabbit holes... Disabling various drivers (eg imx-cpufreq-dt) in the kernel will get past the hang, but result in a crash later on in the boot sequence. Disabling that may get further but will result in a crash somewhere else. My instinct is that its something to do with sdma, but a lot of this is still a black box to me. Any hints or suggestions are very welcome! (I can give more info but didn't want to dump everything straight away) - board is based on an imx8mp module from solidrun - boots kernel ok using u-boot (u-boot version provided by solidrun, based on NXP versions) - I used the same ddr timings from u-boot - also using same versions of firmware-imx (8.16) and ATF (2.8) Cheers Marc
