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

Write current DRL and CRL SHA1 hashes to FLASH using VTRM service:

sudo ./ps3dm -l 0x0 -p 0x1070000034000001 vtrm store_with_update \
