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
