Tool/software: Code Composer Studio

Hi Sir,

We are checking UART to UART communication in TMS570ls0714 BQ76PL455A between But we cannot able to see the cell voltages in bFrame. In TMS570ls3137 Evolution board, Data is not coming when we connected to sciLIN as UART. Than we have connected to sci only and then we got data. In TMS570ls0714 we have connected to sciLIN as UART. Do we need to remove or adding the pull up resistor? Or any other solution require to get data in TMS570ls0714 PCB. Please reply as soon as possible.

Hello Krunal,

The LS3137 HDK uses sciLIN to RX/TX characters through the Micro USB port. The pull-up or pull-down doesn't affect the SCI communication. How does LS0714 interface with BQ part? Does the BQ GUI come up on your PC?

Hi Sir,

Thank you for response. Our PCB is new design . we are checking step by step each portion. we have identify the problem and now UART data is coming.

Thanks and Regards,
