Linux/TIDEP0084: beaglebone black

Part Number: TIDEP0084
Other Parts Discussed in Thread: TMDXEVM3358

Tool/software: Linux

Hi,

I have a question for the processor SDK Linux running on beaglebone black (there is a TI SensorToCloud project, TIDEP0084), the original project using ttyACM0for USB to UART communication, now I'd like to change to the BBB on board UART1(pin-24,26 on J9), tried several things, didn't work. I guess need to enable UART1 somewhere (boot ?), but cannot find any document about this. anybody knows about this?

thank you very much!

    Hi Yue,

    You can check how TMDXEVM3358 board UART is use for console and reuse that approach. UART module and pins is enabled in u-boot DTS file (i.e. am335x-evm.dts).

    stdout-path = &uart0;

    &uart0 {
    pinctrl-names = "default";
    pinctrl-0 = <&uart0_pins>;

    status = "okay";
    };


    Regards,
    Pavel
