Hi All,

I am using I.MX sabre SDB. I am using 3 uarts in my EVB. i am using thm in polling method. I would like to use the same in Interrupt method.

Kindly give some pointers or sample codes to use Interrupts in the Processor under Linux.

I already checked Linux Ref manual, but i didnt find any.

Thanks in advance

Vishva

Hello Vishva,

In the linux reference manual, in the chapter about the Universal Asynchronous Receiver/Transmitter (UART) Driver, you will see where the UART driver is (which uses interrupt method).

Source Code Structure

Universal Asynchronous Receiver/Transmitter (UART) Driver

<ltib_dir>/rpm/BUILD/linux/drivers/tty/serial.

That would be the only available example.
