07/11/2022, 6:21 AMThanks for your comments. So if i understand correctly, the range of user area is from 0x3000_0000 to 0x 8000_0000? What about 0xa000_0000 and 0xb000_0000 space?

07/13/2022, 10:04 AM@Matt Venn Do we now have a accurate date to fix this wishbone access space bug? Our design may need to decide whether to implement a memory remapping or a direct mapping depending on this issue.
