Hello, community


I have some questions about DCD verification.

In IMX6SDLRM ECSPI Boot, there is description as bellow.


The boot ROM code copies 4 KB data from EEPROM device to the internal RAM. If

DCD verification is successful, the ROM code copies the initial 4 KB data, as well as the

rest of the image extracted from application image, directly to the application destination.




Could you tell me the detail of DCD verification(How is the verification done)?



If the DCD verification is failed,what is the next action?


Thank you!
