How To Use Tag-Connect Cables With The ST-Link/V2 Debugger

ST-LINK/V2 Cable Selection & Installation

The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families.

1. Full traditional JTAG using our TC2050-ARM2010 adapter TC2050-IDC 10-pin Plug-of-Nails(tm) cables. Compatible with all ARM processors.
2. SWD (Serial Wire Debug) smaller footprint solution for Cortex processors. JTAG interface ARM20-CTX and the TC2030-IDC cable.
3. SWIM solution for STM8.

Both solutions are similar in that they use a 20-pin to Tag-Connect adapter. However, the Full Traditional JTAG also allows you to optionally power the target from the debugger and provides access to all of the signals provided by the traditional 20-pin ARM 0.1″ connection whereas the SWD (Serial Wire Debug)solution only supplies access to the signals used by the SWD protocol.

Full Traditional JTAG using TC2050 and TC2050-ARM2010 adapter

Both solutions for the ST-LINK/V2 are similar in that it requires an adapter and a cable, so it is up to you which one you will go for depending on your PCB needs. Here is the first solution:

Connect the TC2050-ARM2010 to the ST-LINK/V2 and connect the TC2050-IDC cable to the adapter.

Both “legged” and “no-leg” cables come in the standard 6″ length.
The TC2050-IDC-NL will require the TC2050-CLIP if you want a hands-free solution while debugging.
