Does STlink support AD V2multi-drop SWD?

[Uwe Bonnes]

All STM32 CortexM7 and M33 have a ADI V2 debug unit. ADI V2 requires Multi-drop support, so that several SWD devices can be connected to SWD in parallel. Only with an activation sequence including the target-ID of that device to use selects the device for debuging.

Do Stlink debuggers support multi-drop?

Hello @Uwe Bonnes​ ,

Currently, the ST-Link does not support SWD multi-drop.

I escalated this request internally to the ST-Link team for review.

I will give you an update as soon as there is a plan to make this feature available.
