9.1i EDK - PLB memory addresses are not accessible to debug interface ("ERROR (1059): I-Side Memory Access Check Failed")


Keywords: XMD, PLB Memory, I-Side, Address

I am unable to access PLB Memory addresses from the debug interface with the following error:

"ERROR(1059): I-Side Memory Access Check Failed
Section, 0x00000000-0x000020e0 Not Accessible from Processor I-Side Interface"

When is this problem going to be fixed, and is there a way to work around this issue?


To work around this issue, please take the following steps:

1. Navigate to the project directory -> etc -> open xmd_ppc405_0.opt with a text editor.
2. Delete all information that follows "connect ppc hw -debugdevice cpunr 1" (the deleted information is inferred from the MHS file when the XMP file is passed to XMD).
3. Save the document and open the project.
4. Connect to XMD, and you should now be able to access the PLB Memory addresses from the XMD debugger.

This problem has been fixed in the latest EDK 9.1i Service Pack, available at:
The first service pack containing the fix is EDK 9.1i Service Pack 2.
