Hi Joseph,
I was told you've been using our DE4-230, including the implementation of this DDR2 example design.
After reading through your steps, the first thing I'd check is whether the pin assignment is correct. The other possible cause is whether the parameters defined in the example design meet the criteria of the board and the spec. of DDR2 SO-DIMM used.
It would be a lot easier if you could refer to our DDR2 demo code from section 5.5 DDR2 SDRAM in our DE4 user manual where you get to test the entire the DDR2 SO-DIMM. This can help you confirm the hardware is in perfect condition.
Cheers,
David
Hi David,
Thanks for responding.
I referred to your DDR2 demo code's pin planner for the pin assignment, it should be right.
As for the parameters, I really couldn't find a recommended or formal setting for DE4-230. I tried the parameters setting for your DDR2 demo code according to QSYS file but still couldn't solve the issue. Could you please offer a recommended parameters setting?
I also tried the DDR2 demo code but got the error when executing the demo batch file “test.bat” under the batch file folder DE4_DDR2\demo_batch\dim1 as attached.
Could you please provide some advices?
Thank you!
Joseph
