UART connected to DMA with char HAL API

I am connecting the NIOS II UART to a DMA controller. Is it possible to use the standard HAL character mode API to open, read and write the /dev/uart. Thanks in advance, Joe

In that case you need to write your own driver. The default HAL driver doesn't know how to do that.
