8 years agoWhat I was thinking about in my last point was that those two lines
--- Quote Start --- content = 0xABCD; IOWR_16DIRECT(memory_base, 0, content); --- Quote End --- will overwrite the reset vector, causing the system to be unbootable is the CPU has its reset vector set to the SDRAM. Did you try without this operation? Otherwise the only way I can think about is to use SignalTap on the Avalon masters on the CPU and trigger after a reset to see what the CPU is doing when coming out of reset.
