Hi, all!
I have a PEX device with two memory regions:
Region 0: Memory at 20000000 (32-bit, non-prefetchable) [disabled] [size=512]
Region 1: I/O ports at <unassigned> [disabled]
Region 2: I/O ports at <unassigned> [disabled]
Region 3: Memory at 20000200 (32-bit, non-prefetchable) [disabled] [size=256]
I want to map Region0 and Region3 in user space. Region0 was mapped without any
errors, but on Region3 mmap() return error: Invalid address. I suppose that Region3 must be
aligned at PAGE_SIZE boundary, but then I try to map Region3 with devmem2 it was mapped
this region fine.
It do something like this (sample code):
u8* bar0 = mmap(0x20000000, 0x1000);
u8* bar3 = bar0 + 0x200,
or there is another way to map not aligned addresses?
Thank you.
