My PCI device information is as follows:
Print Begin Configuration space...
BAR 0 start address: f6000000
BAR 0 end address: f6ffffff
BAR 0 flags: 140204
BAR 0 IO / MEM: MEM
BAR 0 PREFETCH NON PREFETCH: NON-PREFETCH
BAR 1 start address: 0
BAR 1 end address: 0
BAR 1 flags: 0
BAR 1 IO / MEM: MEM
BAR 1 PREFETCH NON PREFETCH: NON-PREFETCH
BAR 2 start address: f0000000
BAR 2 end address: f3ffffff
BAR 2 flags: 14220c
BAR 2 IO / MEM: MEM
BAR 2 PREFETCH NON PREFETCH: PREFETCH
I want to write a byte and read it back to BAR2 for a test simple . Is it possible to write a byte to BAR2 start address
Sample code is welcomed.
