TMS570LS3137: SCI DEBUG Messages Implemented In CAN BOOT Loader ( Hardware connections needed )

BarematalProgrammer

Part Number: TMS570LS3137

UART_putString(UART, "\r Hercules MCU CAN BootLoader ");

I am using TMS570LS3137 HDK .I want to use the SCI messages for debugging purpose on the Hyperterminal , what are the hardware pins used for SCI Tx/Rx  or connections that I have to follow . I did not find documentation on this

Should I use (Silicon Labs CP2402 FTDI) USB-> UART device or the SCI messages are being transmitted on the XDS100

    Hello,
    TMS570LS3137 has one SCI and one SCI/LIN interfaces.
    Which pins you have use depends on which SCI port will be selected.
    On HDK SCIRX is exposed on connector J11.44 and SCITX is on J11.49.
    SCI/LINTX is exposed on J11.6 and SCI/LI_RX is on J11.5
    I would use SCITX and SCIRX since SCI/LIN is connected to U27 as well and it could interfere.
    You can use any UART->USB converter with 3.3V signal level.

    Best regards,
    Miro
