TMS570 battery balance management system solution [Copy link]

When I connected the EM1402evm board to the computer directly with TTL wire, the bq76PL455_GUI software can be opened normally and the voltage of 16 batteries can be displayed; but when I connected the TMS570LS0432 to the circuit and connected it to the computer, the bq76PL455_GUI

software kept prompting that the com port could not be opened. (ps: tms570LS0432 has been modified according to the manual, and the hardware circuit connection is normal).

I would like to ask how to deal with this problem? Thank you very much
