This error message occurs when InterCom communication is enabled for TRACE32 on your PC.

InterCom communication is typically required when two or more TRACE32 PowerView applications need to communicate with each other via UDP, as the case in AMP multicore debug sessions.

The "no response from InterCom" message appears when the default 500 ms timeout for acknowledging an InterCom command is exceeded. This can typically happen when several PowerView instances share the bandwidth of a single debug port.

The required bandwidth can be reduced by decreasing the update rate of each TRACE32 application:

SETUP.UpdateRATE <time or frequency>

If this is not sufficient, or if the resulting update rate becomes unacceptable, the InterCom acknowledgement timeout can be increased.

SETUP.INTERCOMACKTIMEOUT <time>

The default InterCom command acknowledgement timeout is kept as short as possible to maintain acceptable PRACTICE execution performance when no InterCom participants are present
