Hi Team,
In our project, we are using S32K146 device.
We are able to communicate with slave device using LIN communication protocol with external 12V supply. We have successfully flashed the code using USB.
As we know, once code flashed there is no need of USB cable. So, we have removed the USB cable and everything running correctly. But when we plugged the USB cable back where external power supply is already present suddenly controller stops working.
Now, MCU is not powering up with USB cable and not showing OPENSDA with Communication PORT.
Is powering the device with USB while external power supply (12V) present caused the problem?
Kindly assist.
Thanks in advance.
Regards,
Punith
