Hello all,

I am using AT91SAM9G20-2slot-mmc-EK.In this board PB10->TXD3 and PB11->RXD3 are used for USART3 module.The Atmel serial driver(Linux) supports without any problems.
I want to use PC24->TXD3 and PC25->RXD3 in my custom board with linux-2.6.30.

Please suggest me how to edit the Atmel serial driver(Linux) code ? or Where to edit ? So that it will support my custom board and USART3 shall work fine.

Thanks in Advance,

Thenral

Hi Thenral,

You don't have to modify the code of the serial driver. The driver is generic, here the changes you want to do are platform specific so you have to see into the arch/arm/mach-at91 folder to find where to do these changes.

So I think you have to edit the configure_usart3_pins function into at91sam9260_devices.c in order to change pio used.
