Understanding the last execution status message at boot-up
93
File not correctly received.
During a local download procedure, the binary file has not been received
properly. At the moment this detection is minimalist.
Header authentication failed.
During a local download procedure, the header could not be authenticated
successfully. This error is reached only if the header stored in RAM is altered
(otherwise the download is bypassed without triggering a critical failure).
Decrypt failure.
Error encountered while decrypting the content of Slot #1. This error reports
a decryption or an authentication issue as the final stage of the decryption is
a check of the signature.
Si
gnature check failure.
Error encountered while verifying the signature of the decrypted firmware
during an installation procedure. In the example code, this error should not
be reached as a signature issue would be captured at decrypt stage
(reporting “
Decrypt failure.
”).
Incorrect binary format (not
encrypted).
Error encountered during an installation procedure: the binary present in
Slot #1 is not encrypted. Maybe the clear version of the firmware instead of
the encrypted version was downloaded?
Flash error
.
Flash error encountered during an installation procedure.
FWIMG pattern issue.
Error encountered during an installation procedure: internal issue while
writing some SBSFU patterns.
Error while swapping the images in
Slot #0 and Slot #1.
Error encountered during an installation procedure: failure while swapping
the images (previous firmware and decrypted firmware).
Firmware version rejected by anti-
rollback check.
Error encountered during an installation procedure: the firmware version
cannot be accepted (newer firmware already installed or lower version than
min. allowed version).
Unknown error.
Undocumented error (unexpected exception or unexpected state machine
issue).
