Hello, I am using an 8275 and map memory. When I map my LEDS physical 0x40000000 to 0x40000000 using a BAT I can hit them, several minutes into execution during a sync, the system hangs.
I have tried to map this to a smaller region using the mmu (io_block_mapping) but when I do the region is no longer accessable. THis is the preferred method as I have a large region at 3000.0000 that I want to map using the remaining BAT. What should I do? Any clues where to search for an explaination of what is going on?
