Hi Heiko,

Thomas Schäfer sees this behavior also on an imx8mn NXP evk board. Thus I added him to this thread.
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?
Thanks
