Dual Port Ram Diagnostic


Recommended Posts

We are having problems with corrupt dual port ram read data. The diagnostic supplied in PEWin is only Write from PMAC/ Verify on PC. I need to operate in the other direction, ie Write from PC/Verify on PMAC. Ideally this test would be able to do $5555, $AAAA, Walking zero, walking ones and checkerboard. Has anybody put together such a diagnostic?

Pewin32 Pro2 now has DPRAM Test as an MDIChild form. The entire DPRAM is tested for integrity of all PMAC locations by writing to each bit and then verifying the data both from PMAC side as well as Host computer side. Finally all locations are cleared before the DPRAM test is complete.
