11 EDK - Why does XMD issue the error "Debug Memory Access Check Failed"?


When I launch XMD from XPS, I receive the following error:

"Debug Memory Access Check Failed"


When XMD is launched from the GUI, it automatically uses the -xmp switch to pass in the project's xmp file. Doing so gives XMD knowledge of the memory map which XMD assumes to be a 1:1 correspondence. Whenever a processor uses the TLB, there is potential that a 1:1 correspondence not exist and XMD will issue the error message. If you are using the processor's TLB, it is best to launch XMD from the command line rather than from the GUI.
