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:
U-Boot SPL 2022.07-rc3-00093-g7d3acf08ec60-dirty (Jun 07 2022 - 14:20:02 -0300) SEC0: RNG instantiated Normal Boot WDT: Started watchdog@30280000 with servicing (60s timeout) Trying to boot from MMC1 hab fuse not enabled
Authenticate image from DDR location 0x401fcdc0... bad magic magic=0x0 length=0x00 version=0x0 bad length magic=0x0 length=0x00 version=0x0 bad version magic=0x0 length=0x00 version=0x0 Error: Invalid IVT structure NOTICE: BL31: v2.4(release):lf-5.15.5-1.0.0-10-gcb51a0faa4b6
The problem seems to be related to the TF-A version.
If I use the older imx_5.4.47_2.2.0 TF-A then the sha256 calculation via CAAM does not fail.
