    • If this issue is observed, then the samples need to be replaced.

      Random failures were seen in the SBL & application boot (ATF/Linux).  Inserted a memory check just after Board_init(DDR) in the SBL and then we saw memory failures in certain sections in DDR about 1 out of 3 times.

      Reverting the PDK commit below(for DDR-4266 Register Settings) makes all the problems go away:

       "PDK-8145 Board: J721E DDR: Check-in Latest DDR Configuration Revision: 0.5.0"
