Hello All,

I am working on i.MX 35. I tried to understand uart functionality using SDMA, but i did not get clear picture .

As per Reference manual :

DMA TX /RX interrupt will trigger on FIFO level , but the backs provided by SDMA , is not working as per data sheet described .

Can you help me to understand of SDMA for UART (or) Any document for this

Thanks

Amuru

There is a Chapter 42 in the i.MX35 Reference Manual talk about SDMA controller in details.

We don't have much example talk about SDMA.

Hope this information can help you.
