    Hi Ethan,

    Please try modifying the uart_open_close_v0_lld.h.xdt file present at ${SDK}\source\sysconfig\drivers\.meta\uart\templates location.

    Change the array index from CONFIG_UART_NUM_LLD_INSTANCES to CONFIG_UART_NUM_DMA_LLD_INSTANCES. Please refer code below.

    extern UART_UdmaChConfig gUartDmaChCfg[CONFIG_UART_NUM_DMA_LLD_INSTANCES];

    After making the above changes rebuild the example.

    Please let us know if the above works.

    Regards,

    Tushar
