Facing the issue XCP internal error: timeout expired

Top model targets built: Model Action Rebuild Reason ===================================================================== blinky Code generated and compiled. Incremental checksum changed. 1 of 1 models built (0 models already up to date) Build duration: 0h 1m 31.43s

Selected serial baud value (9600) can introduce a significant delay in target response when transmission bandwidth is saturated. Consider using a higher baud value.

I'm using F28P65x board from Texas Instruments and im trying to build a program. However, I'm facing the above mentioned timeout error. I have tried different osckclock frequencies and baud rates but getting same results. Please guide me on this.

Hi @Pratiksha,

A screenshot of the hardware implementation would be greatly appreciated. Additionally, you might find these post discussing a similar issue helpful:

Hi @Pratiksha,

The baudrate of 9600 is very low. Can you check and increase the baudrate to 115200 atleast and try monitor & tune? Also it would be good to verify if the serial communication is working by trying out this example https://www.mathworks.com/help/ti-c2000/ug/serial-communication-example.html. That atleast helps to narrow down the problem.

Thanks,

Aditya
