One more comment to add. When I look at the xparameters.h, I only see a single difference:
#define XPAR_MICROBLAZE_HW_VER "8.50.b"
instead of
#define XPAR_MICROBLAZE_HW_VER "8.40.b"
Which I believe should not create a problem.
I also attached two system.xml files. One of them is the one provided by Analog Devices, you can see it from its path in one of the first lines of the xml file. The second one is the one generated after "Export Hardware Design to SDK."
