Hi @collin.tx
According to this link it seems that this security meta layer was tested with Verdin IMX8MP.
But can you please confirm that this has been tested with Verdin IMX8MM as we are having that hardware platform?
Here are my steps:
I added the security meta layer and added tdx-signed
Then using cst I generated the keys and issued the bitbake command to compile the OS image.
Then I used Verdin-iMX8MM_ToradexEasyInstaller_6.6.0 as a base and updated the imx-boot-sd and imx-boot files.
Finally I executed recovery-linux.sh
I have the keys so I hope we can recover the board.
Thank you
