How to force a connection to a PowerDebug which is already in use?

If you see a dialog box with the message "TRACE32 device already in use" then one of the following has happened:

1. You've started TRACE32, while another TRACE32 GUI is still exclusively connected to the same PowerDebug box.

2. TRACE32 PowerView was previously not properly closed (e.g. killed or crashed).

3. You have started a second TRACE32 for an AMP multicore scenario, but the second GUI wasn't configured with CORE=2 or the first GUI wasn't configured for CORE=1.

If you want TRACE32 to automatically to force connection to the PowerDebug box by resetting it, use the statement CONNECTIONMODE=AUTOCONNECT in the PBI= section of your TRACE32 configuration file.

Example for a USB connection:

PBI=USB
CONNECTIONMODE=AUTOCONNECT

If you want TRACE32 to automatically  close the new TRACE32 session, use the statement CONNECTIONMODE=AUTOABORT in the PBI= section of your TRACE32 configuration file (usually "config.t32").


Please refer to the TRACE32 Installation Guide for mode information.
