Both part number is different in speed grade. This is first time I heard about this issue. A quick suspect might due to clock. Can you try to copy pll_config.h that is passing (from 2013.01.01) and replace the one in 2016?
That doesn't work at all. Now it fails to detect the FPGA, then hangs after printing the amount of DRAM.
Can you share with me the pll_config for 2013.01.01 that is working for you?
I don't know that it is. The only thing I've found to work is the unidentified SPL on the SD card that came with the dev kit.
Oh ok, that mean no modification from your side. Let me take a look then on the pll_config.
