Hello @vix,
I tested this again with Torizon OS 7.0.0 and the Cortex-M7 booted successfully.
I tried with both the default firmware and a firmware that is located in the DDR and both worked.
You likely already know this, but when using a firmware located in the DDR, you need to change the addresses in the cm_boot command.
Can you share what procedure you are following?

It’s the same CI/CD pipeline that builds Torizon OS customizing u-boot.
Let me double-check what happens on my side.
