You are right one of the EMIFA pins was used as a FPGA IO, after replacing this pin everything works as expected.
Th... Ahmed Shaaban

07:27 AM Software Development: RE: NAND Flash reading problem

And of course, one workaround might be to load the ARM application into memory from NAND first, then configure the FP... Michael Williamson
