So, I'm trying to r-jtag this thing and I already have a Jr programmer v2 And cr4 xl to install. I understand that this is possible with no qsbs or anything, just wire and those 2. Then some people say that you need a post out v2 qsb or something. Anyway can someone tell me the right wiring if I can just do a wire only install? If not, let me know everything that I do need. Thanks.
