Firmware Package: STM32Cube_FW_H5_V1.6.0 Product
Problem
DA regression fails with timeout. I cannot recover the board.
I was trying to run the STiROT Template example (STiROT_Appli) on the STM32H573I-DK board.
1. I ran a custom provisioning script (based on ob_flash_programming.sh + obkey_provisioning.sh)
2. During image flashing step, I accidentally flashed an unsigned binary (appli.bin) instead of the signed image (appli_init_sign.hex)
3. OBKey provisioning (DA_Config.obk, STiRoT_Config.obk, STiRoT_Data.obk) may have failed due to the MCU being in an unstable state
4. I then set Product State to PROVISIONED (0x2E)
Discovery output Discovery succeeds and shows
- PSA lifecycle: ST_LIFECYCLE_IROT_PROVISIONED
- ST provisioning integrity status: 0xf5f5f5f5
- ST HDPL1 status: 0x1
- Permission: Full Regression is listed as available
Regression attempt Using default keys from the firmware package (not regenerated):
- Key: DA/Keys/key_3_leaf.pem
- Certificate: DA/Certificates/cert_leaf_chain.b64
- Password: DA/Binary/password.bin
DA/regression.sh Result
Question
The provisioning integrity status 0xf5f5f5f5 suggests OBKeys were not properly programmed.
Is there any way to recover this board from PROVISIONED state when DA authentication fails due to missing/corrupt OBKeys?
Thank you
