TMS570LS0432: TMS570LS0432

Part Number: TMS570LS0432
Other Parts Discussed in Thread: BQ76PL455EVM,

Hi，

I am trying to program the TMS570432 Launchpad with the sample code provided by TI to work with the BQ76PL455EVM.

I see the "NOTE: Make sure that the resistor R8 is removed on the TMS570 Launchpad board."

 It's that mean R8 resistors need to be heat and remove with a soldering iron?

I have a question : I found that the circuit diagram R8 in the design document is 0 ohm. After removing it, the circuit is open, right?

If  circuit is open the pin38  SCI1_RX can work normal to receive BQ76PL455EVM data?

    Hi Kuanlei,

    Can you provide more details?

    TMS570LS0432 has only one SCI module. If SCI module used to communicate with BQ76PL455EVM, R8 and R9 should be removed and wire the SCI TX/RX to BQ EVM.

    Hi QJ Wang,

    Thank for your reply！

    I am worried that removing the resistor will damage the TMS570 circuit board.

    Because I see the  design document R8 & R9 is 0 ohm that mean this circuit is Short circuit.

    So,I think when I remove R8 & R9 the circuit is Open circuit. BQ76 EVM can't communications with TMS570.

    This is my worry.Because I only have one board.

    Now,I trust you when you say  " If SCI module used to communicate with BQ76PL455EVM, R8 and R9 should be removed."

     I will go to remove R8 with a soldering iron .

    Hi Kuanlei,

    It's better to ask your lab technician to help. Before removing the resistor, please make sure the SCI is used for BQ76PL455EVM.
