I'm using the Tiva-C micro controller TM4C123GH5PM with keil V5 and I'm having trouble accessing memory where the peripherals are store. 0x4000 0000 to 0x400F FFFF.
When I'm dedugging the target I can't accessing the locations even though the data states its a R/W location.
I can simulate just fine, but debugging actual hardware no access.
Not aware the debugger throws that error, perhaps you can furnish a screen shot of this condition?
