I am learning about X-CUBE-AWS examples, when update from OTA, I get a SIGNATURE CHECK FAILED exception, somebody can help me to resolve this problem?
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
