Debugging STM32F446ZE Nucleo SWD with external ST-Link v2

[HMSEdinburge]

Hello... I'm learning to use an external ST-Link to debug the F446ZE Nucleo using SDW. Can anyone advise on how to connect the SDIO, SDW pin on the Nucleo board to the external ST-Link v2? Additionally, what settings should I configure in CubeIDE to use the ST-Link v2? I also have an ST-Link v3. Any advice on ST-Link v3 is also welcome, thank you.

SWDIO and SWCLK  you mean? SWD ? What's SDW, dyslexia?

You'd need to connect directly to the respective PA13/PA14, most readily via the CN4 jumpers you'll remove to disconnect the local ST-LINK from the STM32 Target.

You'll need to look at the schematic and probe the pins to understand which side connects to what.

You'd need to power the ST-LINK/V2 buffers via a connection to Pin 1 VTarget on the 20-pin header.

PB3 (SWO) and NRST are connected more directly, so might be solder bridges or traces to be cut to adequately separate the them from the on-board ST-LINK

For CubeIDE you'll need to select the debug pod you plan on using.

If you want external ST-Link instead of the on-board one, you likely want the V3. It is faster, easier to connect and has USB to serial interface (aka VCOM).

Yes i would like to learn how to use v3, can it be used for debugging and programming? please advise the connection pin and configuration on CubeIDE, I have both the F446ZE and H743 Nucleo, albeit, the H743 nucleo has a MIPI connector for v3 ST-link..Please advise, thx.
