switch_root from initramfs is failing

pgentili — Fri, 29 May 2020 10:15:07 GMT

Hi everyone,

we're trying to implement an initramfs with the intent of:

Open a LUKS partition (using a key saved on TPM)
Mounting the partition RO
Mounting an OverlayFS
switch_root to the new system

The first part of the script seems to work fine. Our problem is in the "switch_root" part which ends in a kernel panic.

Please note that we have the same problem also without the encryption/overlay part. The problem seems strictly related to the switch_root.

We are using Yocto Sumo and the initramfs image is bundled with the kernel.

Please find attached the kernel panic log.

Thanks!

Paolo Gentili

Hi Paolo

I am afraid such configuration is not officially supported in nxp bsps described

on linux documentation link

i.MX Software and Development Tools | NXP

May be recommended to proceed with extended help of

Commercial Support and Engineering Services | NXP

Best regards
igor
