Make sure the device is correctly identified in the device manager on the PC side
Then check if there is a conflicting port on the PC side, changing the COM port to a different port number in the control panel device manager may solve the problem in case of a conflict.
TI bq series, the hardware circuit must be the same as the EVM board circuit, there is no reason, so that you can use TI's demo program to do the test, saving a lot of unnecessary trouble

The situation is different and it is indeed difficult to adjust. The inability to open the com port is indeed a communication line or setting problem.

If you have any questions, post them on the forum and discuss them together. Different hardware circuits may cause port conflicts on the PC operating system, resulting in different solutions.
