Our hardware is a custom VDD5V Only board based on the iMX28 EVK design.

We have enabled the optional simple RAM test in the bootlets and are receiving the error messages shown below during the test. The same code boots fine to uboot prompt on the EVK but our hardware resets itself after the RAM test. our two prototypes show slightly different errors. I hope someone can point me in the right direction in troubleshooting these RAM errors.


Our RAM chip is Winbond W971GGKB-25
