I download X-CUBE-AWS 1.4.0 to compile and install on my STM32F769IDISCOVERY board, everything running ok, but when I configure it to update new app version from OTA, after reboot is shows:

= [SBOOT] SECURE ENGINE INITIALIZATION SUCCESSFUL

= [SBOOT] STATE: CHECK STATUS ON RESET

     INFO: A Reboot has been triggered by a Software reset!

     Consecutive Boot on error counter reset 

     Consecutive Boot on error counter = 0 

     Consecutive Boot on error counter updated 

     INFO: Last execution status before Reboot was:Executing Fw Image.

     INFO: Last execution detected error was:No error. Success.

= [SBOOT] STATE: CHECK NEW FIRMWARE TO DOWNLOAD

     New Fw Encrypted, to be decrypted

     262080 bytes of ciphertext decrypted.

= [FWIMG] FW installation failed!

= [SBOOT] STATE: HANDLE CRITICAL FAILURE
