Hello, community

 

I have some questions about DCD verification.

In IMX6SDLRM 8.5.4.3 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.

---------------------------------

 

Q1)

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

 

Q2)

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

 

Thank you!
