HAB_INV_ADDRESSS when booting with HAB enabled in iMX8M Mini

[jmmorenog]

Hello, i am suffering some problems when i try to enable HABv4 on a Variscite iMX8M Mini board. I've manually build u-boot from the scratch following the full pipeline to generate the .csf files and attaching it to a flash.bin file. Despite that, I am getting this 2 hab events:

Any ideas of why is this happening? thanks

It seems there is a problem with the u-boot version of varisicite (lf2022), I've just tried to generate the flash.bin with the 2023 version and I got No hab events found message... may be a memory collision problem?

Were you successful in resolving this issue?

[jmmorenog]

I updated the U-boot version to 2023 and the problem went away

[ivan_choo]

Did you end up using any Yocto build? And other such things from Variscite?

[jmmorenog]

I builded Linux kernel, rootfs, dtb and other non uboot related stuff with variscite yocto build. I builded uboot with variscite 2023 source code separatedly from yocto.

The HAB events indicate a failure in secure boot, specifically HAB_INV_ADDRESS. This points to an issue with the addresses specified during the authentication process. Verify that the addresses in your Configuration Sequence File (CSF) align with the actual locations of the images in memory. Additionally, ensure the memory addresses used in the CSF match the addresses where the images are loaded.

Check if there are any discrepancies in the memory addresses or offsets in the CSF, and confirm that the images are correctly loaded into the specified locations in DDR memory. Also, verify the correctness of the CSF generation pipeline, ensuring it accurately reflects the memory layout.

If the problem persists, review the Habv4 documentation and seek support from Variscite or the community forums for more targeted assistance with your specific board and setup.
