2.5. Querying RSU Status

The SDM firmware offers a command for querying the RSU status, providing the following information:
  • RSU status code
  • Address of the currently running image
  • Address of the last failing image (sticky)
  • Error code for last failing image (sticky)
  • Error location for last failing image (sticky)
  • Decision firmware RSU interface version
  • Current image (application or factory) firmware RSU interface version
  • Retry counter value
  • Index of last used decision firmware copy
The SDM firmware also offers commands for the following:
  • Clearing the sticky fields related to last failing image
  • Resetting the retry counter value to zero

The functionality offered by all of the above SDM commands is available from both U-Boot and LIBRSU.
