SWD Debugging multiple devices on one bus.

Question asked by gerth.martin on Mar 8, 2012
According to this paper: 
http://www.arm.com/files/pdf/Low_Pin-Count_Debug_Interfaces_for_Multi-device_Systems.pdf, it is possible to use SWD to debug multiple chips that are all connected to the same debug lines. According to this paper, the SWD Protocol Version 2 is needed. 

I tried this with an STM32F103 and Keil, but I was not successful. Can anyone confirm that STM32F1 series does not have SWD Protocol Version 2 or did I just do something wrong?

Thanks, Martin
