STLINK Pinning incorrect in documentation

Troubleshooting
1

Hi There

I have been trying to debug my Electron for some time in Eclipse. It is a real artform to get it all hooked together…

Anyway.
https://docs.particle.io/faq/particle-tools/eclipse-debug/electron/#eclipse-install-gnu-arm-c-c-
shows the pinning to connect the Particle devices to the STLINK

I believe that this pinning is incorrect.

Here is the pinout document for the STLINK-V2 from ST
http://www.st.com/content/ccc/resource/technical/document/user_manual/65/e0/44/72/9e/34/41/8d/DM00026748.pdf/files/DM00026748.pdf/jcr:content/translations/en.DM00026748.pdf

So. I belive the pinning should be as follows.

STLINK ELECTRON DESCRIPTION
1 3V3 MCU VDD
3 GND GND
5 ------- -----------
7 D7 SWDIO
9 D6 SWCLK
11 ---------- -----------
13 ---------- ----------
15 RST NRST

Here is the (incorrect) pinning from the aforementioned Particle Link
1 3V3 MCU-VDD <----CORRECT
4 GND GND <-----CORRECT (Gnd is also on pin 4 of the STLINK)
7 D6 SWCLK <-------INCORRECT pin 7 on the STLINK is SWDIO
9 D7 SWDIO <--------INCORRECT (pin 9 on the STLINK is SWCLK

Missing nRST

Thanks @marshall for the report! @rickkas7 would you please confirm this?

Yes, they’re incorrect in the small table. They’re correct in the large table, and it’s actually wired the way you have changed it to in the picture.

I made the fix and the change is live in the docs now.

Sorry for the confusion,
Rick
