    Q: How are how UARTA, UARTB and UARTC on the DM37x SOMs assigned in Linux?

    A: Here are the assignments as seen in the Linux BSP.

    UARTA (on SOM) -> UART1 (on the processor) -> /dev/ttyO0 (in Linux)
    UARTB (on SOM) -> UART3 (on the processor) -> /dev/ttyO2 (in Linux)
    UARTC (on SOM) -> UART2 (on the processor) -> /dev/ttyO1 (in Linux)

    The Logic PD Linux Software Test Plan (STP) provides additional information on how to test the UARTs.    The STP is available on the support download website as DM37x Linux BSP Test Results.

    PRODUCTS Included: 
    AM3703/DM3730 Torpedo, AM3703/DM3730 Torpedo + Wireless, AM3703/DM3730 SOM-LV
