4.1 List of Features Supported by OTP Key Writer Flow

  • Signed Key writer firmware for HSM which accepts x.509 customer keys certificate with all eFuse fields configured.
  • Supports programming keys at one-pass customer key certificates.
  • Supports following boot modes - UART, JTAG, USB (only for AM261x) and Flash (QSPI/OSPI) modes for boot for key programming.
  • Supports RSA as well as ECDSA based OTP programming.
  • Supports OpenSSL v3.0.2 and above.
  • Encryption keys (SMEK and BMEK) are made optional. Public keys (SMPK and BMPK) are mandatory fields.
  • Option of using Python script for generating x.509 certificate
  • Following are the keys programmable:
    • MSV
    • SMPK, SMEK
    • BMPK, BMEK
    • EXT OTP
    • KEY COUNT
    • SWREV-HSM, SWREV-APP, SWREV-SBL
    • KEY REV
