I got the Olimex ARM-USB-OCD JTAG Adapter and I am using Win7 64 bit. I got the Blackfin toolchain and I try running "bfin-gdbproxy.exe --debug bfin --frequency=5000000" and all it returns is "debug: bfin: bfin_open ()", "error: bfin: cable initialization failed"

I have tried different USB ports, using Zadig to use a WinUSB Driver instead, but I cannot get past the cable initialization failed.

Any help would be great since I got my scope torn apart on the desk.

Thanks!

CustomEngineerer:
Did you try different cables? Some USB cables are just crap and can give you real problems. Try a short, quality USB cable if all else fails.

Edit: By quality I don't mean a $50 1 foot gold plated monster cable or anything like that, just a cable from a reputable company.

OsiViper:
Yea. Tried 3 different cables, none wanna work.

Tried wiring it up using the pull-up resistors as well as wiring TRST and SRST right in instead and nothing seems to make any difference .

OsiViper:
Well. It wasn't an adapter problem or my wiring. Was something with the drivers in Windows. Had been meaning to install Ubuntu on a external hard drive, so just did that, got Blackfin for Linux and ran it. Working just fine now, doing the dump right now.
