I知 having problems using the UART DMA in the interrupt mode

I知 having problems using the UART DMA in the interrupt mode. I知 avoiding the process of reading the UART byte in the RX channel as they arrive. Instead, the DMA has been set to trigger after 16 bytes so that the interrupt for every byte wouldn稚 delay the processor.
I would like to know if there is a way to fire an interrupt on every DMA FIFO full. Please find the code attached and let me know of what I知 doing wrong. Also, I would like to know if there is a interrupt driven UART DMA example available.
