Hi,
I encountered a similar error with my STM32 board. One possible cause is exceeding the available bandwidth of the XCP connection. Here are some steps that helped me resolve the issue, which you might find useful to try:
Decrease the number of signals you are logging at the same time. Increase the clock speed and baud rate of the hardware board. Note that you may also need to reconfigure scalars and timer constants. Split the model into two parts. Use one model to perform any heavy computation work, and deploy this using code generation. Use a second Simulink model running in external mode to log the signals produced by the first model.
I hope this solution works for you as well!
