  1. Regarding https://forum.digilentinc.com/topic/4710-spartan-3-starter-board-help/ and https://forum.digilentinc.com/topic/4784-s3-starter-board-programmer/

    I do not have a second FPGA board - I only have the parallel-2-JTAG adapter-cable that comes with the board. I am wondering if this adapter-cable is still working with modern Laptops USB-Parralel adaptors ?


    Do you have any experience ?

      Not really. If an adapter costs as much as CMOD-A7 that I use in the project you might as well buy one of those FPGA boards; then you can replicate the project as presented. If you want to try and get a modern PC working with a parallel port then I suggest that you stick with an OS like Linux. The project that you refer to is a good reference for one way to configure older devices if all of the required signals are exposed to a connector. If you want to save money but have the time there's no reason why you couldn't use a microprocessor to do the programming. A lot of FPGA device embedded in PCBs with a micro are configured that way instead of using a separate flash device.

      I see and learned that its not worth spending too much time on the old board. I will look into one of the new small FPGA boards available. Thanks for your reply.
