RamTester Fail


I’m trying to use the RamTester that comes within opalkelly’s samples, but it fails. I’ve searched in opalkelly forum and I found out that it could be an memory initialization problem. But checking the verilog code, it seems it’s doing the initialization well. The results of RamTester are:

Is there another version of RamTester (bit file, exe file), please?

Thank you,


Which version of FrontPanel do you have installed?

The latest on the forums is 3.0.11.

Oh, I have the 3.0.10.

Where can I download the newer version, please?

Also, when I try to download something from the forum, I get:

Thank you!


Please see this post:


Thank you very much. Email sent.

Where can I download the newer front panel version (3.0.11), please?



Oh, don’t worry.

I ve already got the 3.0.11 in the forum.


*But I still get the fail message. Anything wrong with it?

Cheers and thank you,


@Joao- What is your current PLL configuration on the XEM3005? Have you changed the EEPROM settings from their default?


My PLL confs are: (I think that changes in the confs were made once, months ago)


Is this OK?

What are the correct parameters, please?



The defaults for the XEM3005 are:
P=400, Q=48, DIV1=VCO/4, DIV2=VCO/8
Output 1: DIV1BYN, ON
Output 2: DIV2BYN, ON
Output 3-6: OFF
