I have a similar issue : when I connect the target ( core 2) , not core 0,1 and 3

Invalid CIO command (0) in the CIO buffer at address (0x8BA7DE48) was not recognized. Please check the device and program memory maps.

I am using Version: 8.2.0.00007, and target is TCI6618.

then later i have the message :

abort() at exit.c:99 0x12821C0 (abort does not contain frame information)

Hello Philippe,
The thread you referenced has some good suggestions on what to check. Also for multi-core devices like the TCI6618, this error is common when dealing with shared memory of a multi-core device. Also make sure that the CIO buffer (at the label CIO_BUFFER) is NOT shared between cores, or that you've taken appropriate measures to protect access to it such an environment.

Thanks
