Question

Hello! Thanks to your help (link bellow), I could make my first design, and generate PROM file with iMPACT. But when I start Configure Target Device, I get this: "An iMPACT project file exists, but no target device has been designated. Click OK to open iMPACT. You will then need to designate which device in your configuration chain is the target device ...... " Is this a bug, or I really missed something? I have attached some console-log of iMPACT.

Hi Peter,

It is possible to directly program the bitfile for almost any Xilinx chip from (say) a Pi, e.g. see here:

https://github.com/yuyomagico/rpi-jtag-spartan3

Another example here using a BeagleBone Black, not tested for many years though:

BBB - FPGA / CPLD Programmer for the BeagleBone Black

There are lots of examples of source code doing this, because Xilinx published the core code to do it, and it can connect to microcontroller boards with no additional interfacing circuitry required.

I don't know if this is what you're trying to do, or if your particular board doesn't expose the JTAG connections and you are forced to use the existing USB connection, in which case please ignore.

Maybe this is it https://forums.xilinx.com/t5/FPGA-Configuration/DLC10-iMPACT-on-win10pro-issue/m-p/918016 " Xilinx ISE 14.7 and IMPACT 14.7 Lab tools are not officially supported for Windows 10. So, you need to use workaround provided at https://www.xilinx.com/suppor t/answers/62380.html for Xilinx ISE 14.7 to make it work on Windows 10 platform. " Sorry about that. Seems odd that Xilinx would create a Win-10 compatible set of tools but then have a key component not work, but it appears that is the case here. Bryan

It is not JTAG, but PSoC MiniProg by Cypress: CY3217 CY3217 . The kit is USB-powered. (AVNET SPARTAN-3A Evaluation Kit)

What's the Cypress programmer for. Are you trying to reprogram the microcontroller? Probably best not to at this point, unless you know the fpga/flash programming stuff is missing and you're trying to restore it back to what was originally there. This looks like it's the manual for the programming utility that Avnet supplied for programming the FPGA. http://www.public.asu.edu/~kyle135/Supplementary/FPGA/SPARTAN3A/User%20Guide/Avnet%20Programming%20Utility%20(AvProg)%204.05%20User%20Guide.pdf IMPACT, within ISE, won't know anything about this board (they wouldn't have had a separate programming utility if they'd done a deal with Xilinx to build it into IMPACT). The utility looks like it was written for XP/Win 7. You might get it to run on something more recent.

This (alledgedly. I could find no active support page, group, for this kit anymore) software with driver for that combination still seems to be available. https://avprog.software.informer.com/versions/

Looks like this may have been a common problem back the. See this Xilinx forum post for an alternative method of launching. https://forums.xilinx.com/t5/FPGA-Configuration/Xilinx-14-7-Impact-error/td-p/675370 Bryan
