Hello Jeremy_S,


Perhaps you could examine the PC's environment. Are the software versions and required software the same on both PCs?

Hi Fakhrul,

Thank you for the response. Both PCs are using Windows 10, Quartus 20.4, using the same .jic files on the same FPGAs, same USB blasters and related cables.

Is there something specific I should be looking for with the PC that could be causing this issue?

Thank you

    Hi,
    some download cables (e.g. Arrow Blaster, I think also USB Blaster Ii) are storing JTAG frequency settings on the computer. Also some global Quartus programmer options may affect operation.

      Hi,

      Yes, both have the frequency set to 16 MHz and the global options are the same. (Assuming that's the menu where you hit tools/options in the programmer)

      Thank you.
