Yup - that's close. The trick is that it needs to be 2x5 (mini/.127) to 2x7 (full-size/.254) to match the DediProg. Or, of course, a simple pitch changer to go from .127mm to .254mm.
Sounds like I complicated life by going with the DediProg that Intel recommended!
Thanks for letting me know what you're using.
Hi, Diego –
The cable I have is a gen-1 cable; it definitely doesn't fit. Both generations use 2x5 headers, but the first generation appears to use .1" (2.54mm) pitch and my Gen-2 definitely uses .05" (1.27mm) I've attached a picture of the cable next to the connector (which also changed position; it's on the bottom now); the difference is very obvious.
While I suspect (hope!) that the pinout is the same, the connector IS different.
Am I the first person to run into this?
Well, I figured it out. As I suspected, it was my mistake all along. Diego, thanks for pointing me in the right direction; I made this much harder than it should have been.
The SF100 isn't connected to the JTAG connector, but the SPI flash connector - the white one on the upper-right of the FRONT of the board. That's a 7-pin .1" pitch header, and matches up with the ISP1-CB cable that came with the DediProg.
Everything is working fine now.
