DRL and CRL Hashes
- DRL and CRL SHA1 hashes are store in VTRM FLASH region.
- First 14 bytes are SHA1 hash of DRL. Then follow 14 bytes SHA1 hash of CRL.
Read current DRL and CRL SHA1 hashes from FLASH using VTRM service:
sudo ./ps3dm -l 0x0 -p 0x1070000034000001 vtrm retrieve 0 | xxd -c 16 -p 8f0652bc6162a240362f90f1b2e5405b b82ee50296791f41f9a76f4d895dd582 0db108ec03d192500000000000000000 00000000000000000000000000000000
Write current DRL and CRL SHA1 hashes to FLASH using VTRM service:
sudo ./ps3dm -l 0x0 -p 0x1070000034000001 vtrm store_with_update \
