Can't debug two instances at the same time

Postby DaveB » Mon Jan 21, 2019 9:07 pm

Hi All, I running Atollic TrueStudio v9.1.0

I am trying to debug a SPI bus running between a STM32F030R8 Nucleo board and STM32H7423 Nucleo board. I have the debugger configured to use the specific ST-Link S/N which I configured one at a time and verified that each one works independently.

Steps:
-Start debugging on one of the boards (doesn't matter which one). Step thru code and run, works fine.
-Attempt to start debugging on the 2nd instance of TS and immediately get a pop up window "Problem Occurred"

" Error in initializing ST-Link device. Reason: (-1) Unknown. Please check power and cabling to target. "

If I stop debugging the first instance and try again it works. But of course now the first instance will fail..

Any ideas? I really don't want to have to run a second machine to do my debugging...

Thanks
