Goodmorning.
I'm working with RT1172 cpu that manage an emmc memory. The software is working fine.
Now I'm testing the OTFAD encryption and the secure boot.
I'm using the MCUXpresso Secure Provisioning to flash the board. With the encrypted OTFAD authenticated and the HAB disabled all works fine. Now I enabled the HAB, the firmware starts but gets an error when CAAM_init is invoked. The function caam_out_job_ring_test_and_remove fails.
What's wrong? Are there any fuse that I'm missing to burn or are there any special configuration needed for CAAM when HAB is enabled?
Thanks

Hello.
It seems that the problem was that we were calling the CAAM_init function twice in the firmware with the encrypted OTFAD authenticated boot and the HAB enabled.
This generated an error when calling the CAAM_RNG_GenerateSecureKey function.
After removing the wrong CAAM_inti call, the CAAM initialized correctly.
Thanks for the answer anyway!
Is it possible to get support on this issue?
