Hi, I am trying to communicate and read values from the onboard LSM303AGR accelerometer from my STM32F411VET Discovery board in Simulink. I am using a USB TTL232 RPI cable for serial communication where the three pins are connected to GND, PB6 (SCL) and PB9(SDA)
I have used the correct COM port from the device manager however, I am not able to connect the model to my target hardware. I have the following error
"Error:External Mode Open Protocol Connect command failed Caused by: Could not connect to target application: XCP internal error: timeout expired, in response to XCP CONNECT command"
Could anyone confirm how to get serial communication working matlab for this board. I have not seen any solutions online and was hoping to get some help on the same.
Thank you.
