Have you tried running it with sudo (sudo ./xpc init and sudo ./xpc identify)? Also, can you please post the output of sudo lsusb?

[Silveriomrs]

Sure:

Sorry for this lines crossing texts, I don'tt know how to remove them

[fuger222]

Thanks! Looks like your cable uses an FTDI chip, but mine has a Cypress FX2, which I originally made this tool for. I've uploaded a new version, which should detect everything, but it can't load bitfiles yet. Can you try if sudo ./xpc identify works with your cable? You'll also need to install a package called libftdi1-dev, if you don't have it already.

Don't worry about those crossed lines, though. There's a button above the text editor that you can use to insert a code block. It looks like this: <> Anything you write there shouldn't be crossed over.

[Silveriomrs]

I will do it now. Whatever, do you prefer to do a remote control to check it out by yourself?

In few minutes I will post the result.

1. libftdi1-dev, was not installed. Now it is.
2. The code:

[fuger222]

Looks good so far! You could try sudo ./xpc identify with the latest version, which should also read the serial number of your FPGA. The reset and load commands should work too.

[Silveriomrs]

Hi, It is the output. Identify seems to work better but not reset nor init. Load didn't try

[fuger222]

Fixed. Init is actually unnecessary in your case, since your cable doesn't need a firmware to be loaded each time you plug it in. You can safely ignore that.

[Silveriomrs]

What is fixed? Should I try to load a jed into the CPLD? Is there a new ver that fix the issue?

Not sure what you mean.

By the way... I see your APP can program bitstream files... for FPGA, but what is about JED files (for CPLDs), in words of Xilinx it cannot be converted between JED to/from BIT.

I am trying to program a Xilinx CPLD. Is it possible?

[fuger222]

I thought only the cable was unsupported, but yes, this is another problem. Bitstream files contain literally just a stream of bits, that this app sends to the programmer cable (pulls the TDO pin to GND or VCC based on whether the bit is 0 or 1), but JED files only contain the states of individual fuses, which need to be programmed in a different way. Considering how much time it would take and the fact that I don't have a CPLD to experiment with, I don't plan making it compatible with CPLDs and a completely different file format, in the foreseeable future at least. Sorry about that. I'll leave this issue open in case someone finds this project and decides to work on CPLD support.

If you haven't already, you could try openocd, maybe they have support for your cable + CPLD pair.

[Silveriomrs]

Thank you :) I will try it with openocd.

Thank you for your great work. :)
