LP-AM243: LP-AM2434

Hi 

I am using uart_echo_am243x-lp_r5fss0-0_nortos_ti-arm-clang example code. I am unable to assign other uart pins apart from uart0_RX/TX.  Help me resolve this 

Thanks

    Hi,

    The question you have put is unclear.

    Did you mean to say you cannot add another UART peripheral? For example, do you want to add UART1/UART2 and so on?

    If that is the case, then you can click on the "Add" option.

    Thanks,

    Hi

    I am able to add another UART peripheral but suppose I assign B12 and A12(UART1), when I run the code, it is not responding as intended. I am able to build the code with no errors but when it is debug mode it stops after the debug line "[UART] Echo example started ...\r\n" 

    It works as intended when UART0 is assigned,

    Hi Yashaswini,

    Let us understand why this is happening for UART1 and not UART0.

    For example, when using UART0 you must have seen the application running fine and you able to input characters as well into the console.

    But for UART1 it is not happening.

    Let us refer the AM243-LP Schematics to get started.

    Please see the UART0 and UART1 in the above Block Diagram from the schematics.

    UART0 is connected to USB MicroB and not any other UART(which includes UART1). Hence you would not be able to see the output on the console, due to which you cannot input the 8 characters and hence the UART echo will not work for UART1. Note, it will work if UART1 is connected in a similar way on your custom board.

    Thank you,
