Hi,

In Linux, EDMA is used in my many kernel drivers, UART driver (8250_omap.c) is one of the examples.

I apologize if it is very dumb question. But after compilation and insertion 8250_omap.ko , what other thing I have to do in my user space application:

like how would I get the data, how my application will know some data has been received etc. Can u provide me sample user space application to interact with the driver?
