9.1i iMPACT - Verify fails when an operation on an SPI M25P65 device is connected to a Virtex-5


When using iMPACT to verify the ST Micro SPI device, M25P65 failure can occur at address 0. The following will be displayed.

Failed at address, 0

'1': Verification Terminated

PROGRESS_END - End Operation.

Elapsed time = 3 sec.

The contents of the PROM have been programmed, and the device can successfully program the Virtex-5. The problem is in the way iMPACT is operating on the device.

The first service pack containing the fix is 9.1i Service Pack 2.
