Thanks, Phil. I will see what the 2013.01 debug produces. But below is
what I see if I add DEBUG to the 2016.03-rc3 code.

Marek -
The marking on my DDR parts is 4NE77 D9PXV which translates to
Micron part# MT41K256M16HA-125:E. I was looking at the data sheet
to see if I could further manually relax some of the settings in
sdram_config.h. I was also wondering what DDR parts you have on your
boards. Given that your two Rev. D boards work fine, I'm beginning to
think mine is defective and I'd be better off to get a new one.

Best regards,
