Hi,
BOARD: a board with TI dummy key and a board with customer key
SDK: 8.0
STEP:
1. For ES1.1, first modify PSDKLA/makefile
SYSFW_MAKEARGS_hs = HS=1 SYSFW_HS_PATH=$(TI_SDK_PATH)/board-support/prebuilt-images/ti-fs-firmware-j721e_sr1_1-hs-enc.bin \
SYSFW_HS_INNER_CERT_PATH=$(TI_SDK_PATH)/board-support/prebuilt-images/ti-fs-firmware-j721e_sr1_1-hs-cert.bin
2. Follow https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1061584/faq-tda4vm-hs-building-booting-on-hs-devices-on-latest-linux ，building binaries and copy them into the SD card, power on the board with TI dummy key
3. Replace TI dummy key with customer key
cp customerkey.pem PSDKLA/board-support/core-secdev-k3/keys/custMpk.pem
4. Follow step 2 to rebuild and power on the board with customer key

The console output log of the board with TI dummy key, see attachment.
The console of The board with customer key has no log
By the way, The board with customer key works fine, I can start and output the log through sbl boot.
Is there anything else that needs to be paid attention to in the SBL boot of the customer key?
BRs,
Allen
