I would like to try DDR test in the IMX_OBDS for my custom i.MX28 board.


Is the MMU/d-cache enabled during DDR test of OBDS?

OBDS: On-Board Diagnostic Suit for the i.MX28(REV 1)


In addition,

I found following descriptions in the i.MX28 reference manual;

- To accelerate the boot process, the MMU/d-cache is enabled during the time consuming
HAB authentication process (RSA).

- MMU and D-Cache are enabled in default to speed up HAB functions
execution speed.


Is the MMU/d-cache enabled during normal boot?


Can someone help me?
