torizoncore-builder - add an option to specify a M-Core firmware to be loaded by uboot

Feature Requests

In some cases with HMPs like iMX8MM or iMX8MP, Core-M firmware is loaded by uboot (not by remoteproc driver in Linux) - see this KB.

This topic describes how to automate the process of this loading during the boot.

Basically:

  • include the .bin firmware into TorizonOS TEZI image
  • customize u-boot-initial-env-sd file in TorizonOS TEZI image

I do this with a custom python script in my CI/CD pipeline.

But I think that since this could be a general need, a new option could be added to torizoncore-builder, so that inside tcbuild.yaml the user can specify a firmware to be loaded by uboot.

Thanks.

Hi @vix!

I already discussed with Torizon team. Unfortunately, they cannot prioritize it at the moment, but it has been tracked and will be addressed when possible.
