XEM7310, RAMTester

Hello!

We recently bought a new XEM7310 200A and have used the 75a version before. We are running the sample RAMTester software and it does not work. Bellow is the output,

THIS IS A BRAND NEW FPGA, would this mean the FPGA is defective or is there a ferrite bead or some other thing we must do for the DRAM to be enabled.

Probably neither.

The write time is suspiciously close to exactly 10 seconds and your tests terminate in a timeout condition. This would suggest that the transfer required more than the allowed time to complete and, therefore, failed.

What parameters are you passing to PipeTest? What is the speed of the port you’re using? What operating system are you running this on? What other tests have you tried?
