PCI CD/CDa Configurable DMA Interface User’s Guide Testing

EDT, Inc. May 2007 9

Testing

When you run this test, the PCI CD/CDa is configured with the FPGA configuration file xtest.bit. For

normal operation, reconfigure the board with

initpcd after completing the test, as described in

Loading the UI FPGA Firmware and Configuring the PCI CD/CDa on page 8, to reconfigure the board

with the correct UI Xilinx configuration file.

To verify that installation was successful and that the PCI CD/CDa is operating correctly, run

xtest.

At a command prompt, enter:

xtest -i 4096

The number following

-i specifies the number of bytes to test. The PCI CD returns test status

information. The following is an example of proper behavior, although details will vary:

reading 4096 words

buf at 820000

testing dirreg at 4 4

testing dirout at 8 8

testing dirin at 8 c

testing ctlout at a a

testing ctlin at a e

Calling DMA read 8192 at 820000

return to do read:

read returned length 8192

Done.

Problems are indicated by the string

ERROR - followed by an error message. If you do not see such a

string in the output, then the test completed satisfactorily.
