[quote user="Johan W���lger"]I am positive that I did run this setup in previous CCS versions (both CCS4 and some earlier CCS5 versions), and I don't remember doing any manual configurations before launching two simultaneous debug sessions. Any ideas what might go wrong or if I should do some setup or configurations before trying the simultaneous debbuging?[/quote]I think the problem might be the BlackHawk USB2000 driver has a bug.
CCS Debug Crash is a recent thread which mentions a Blackhawk Update Package was required to stop a CCS 5.3 crash when using a single BlackHawk USB2000 (but doesn't give the version of the update).
A single BlackHawk USB2000 is working with CCS 5.5, using Blackhawk CCSv5.5 Emulation Update version 5.5.0.340
However, when attempted to use the BlackHawk USB2000 with CCS 6 beta 3 with Blackhawk Emulators version 6.0.0.102:
1) Attempting to test the connection failed,since it caused the dbgjtag.exe to crash:
2) Attempting to connect using the Blackhawk USB2000 caused CCS 6 to crash (and exit without any error messages).
On the second session in CCS, what happens if you attempt to test the connection rather than connecting to the target?
