Cmod S6 - trying to program flash - "initilaize chain" does not work

[Rom123]

Hello everybody,

It's the first time for me working with FPGA's so I chose a Cmod s6 board.

I did my software so far with Xilinx ISE 14.7, did the connection from the computer (Win 7, 64Bit) to the board (On-board USB port) with just a normal USB-cable and transferred the software with Digilent "Adept" directly to the FPGA. The problem is, everytime I pull out the plug from the cable, the software gets lost. So I have ot transfer this PROM-file, generated in "iMPACT", to the flash. The generation of the file also works

But the problem is: If I try to initialize the chain, it doesnt work. It says:

I already uninstalled the driver twice and reinstalled it like suggested in another Digilent Forum chat, used different USB-cables, made a couple of restarts, tried different settings in the cable setup - without success!

What is wrong? Thanks for help in advance!

@Rom123,

I expect someone from Digilent will answer shortly, but thought I might provide my own response as well.

I always programmed the flash myself.  It wasn't all that hard, and you can find all the software I used to do it within my own S6SoC project.  Basically, I'd load a special design using the traditional tools (I called this alttop.bit), and then communicate with that design over USB/UART to load a new design using my own zipload command as I called it.

Feel free to check it out if it helps, otherwise I'm sure Digilent will step in,

Dan

Hi @Rom123,

Welcome to the Digilent forums!

Here is a forum thread that discusses the process for configuring the FLASH on the Cmod S6 in ISE.

Are you following the steps in the linked forum thread?

Please attach screen shot of your process in iMPACT.

best regards,

Jon

Hi jpeyron,

I already found that discussion and yes, I followed the steps. But even before creating a prom-file, the "initialize chain" is not successfull.

What do you exactly mean with "process"?

Thanks (also to Dan for the help)

Hi @Rom123,

So for the confusion, please attach screen shot of each step taken in iMPACT.

Please install Adept 2 here. Does adept 2 recognize the Cmod S6?

Did you install the digilent plugins here? 

best regards,

Jon

Hi jpeyron,

it works! I found it quiet complicated to find out in which directory I had to put the files.

So I tried and tried and tried... that was the important part.

 

 

Thanks for the support and thanks for having this forum!

Hi @Rom123,

Glad to hear that installing the Digilent Plugin resolved the issue. Thank you for sharing what you did to fix this issue.

best regards,

Jon
