Well your .gel file is working now, so that's some progress.

Have you tried supplying an ECLKIN signal? Regardless of whether you are making sync
or async memory access, I wouldn't count on any successful EMIF behavior without a
valid ECLKIN signal.

Also, don't worry about DMA and HPI at this point. Your test C code should just make
repetitive access to CE2 so you can see it on the dig scope, and don't forget to use
volatile keyword.
