Thanks for the feedback.

I managed to reproduce the problem on an imx8mm-evk board.

On top of tree U-Boot I added:

--- a/configs/imx8mm_evk_defconfig
+++ b/configs/imx8mm_evk_defconfig
@@ -87,3 +87,4 @@ CONFIG_SYSRESET_PSCI=y
 CONFIG_SYSRESET_WATCHDOG=y
 CONFIG_DM_THERMAL=y
 CONFIG_IMX_WATCHDOG=y
+CONFIG_IMX_HAB=y

Then I try to load the fitImage and the sha256 calculation via CAAM fails:

Peng, Ye Li, Gaurav,

Any suggestions?
