AM625: Failed to verify hash of fitImage in Secureboot

Part Number: AM625

Tool/software:

I'm testing secure boot with SBL.

I could boot until U-Boot but the verifying hash of fitImage was failed.

U-Boot tried to find node named "signature" but it seems was failed.

name_fit_config=conf-ti_k3-am625-custom.dtb
## Loading kernel from FIT Image at 90000000 ...
   Using 'conf-ti_k3-am625-custom.dtb' configuration
   Verifying Hash Integrity ... fit_config_verify_required_keys: No signature node found: FDT_ERR_NOTFOUND

The node name is defined as FIT_SIG_NODENAME in include/image.h, and it is same with am62xx-evm.

What is the reason that the verifying is failed when devicetype is changed?

 

MCU+ SDK: v11.00.00.16

PSDK: v09.02.01.09
