Hello,

Can anybody tell me how to disable the peripherals which I don't want use during execution of my program? My application needs only USB (for the wireless card) , Ethernet port,  Timer and debugging serial port. I need to be sure that the system wont be disturbed by the other peripherals.

Thank you for any help.

Some of the drivers needs to be disable via kernel configuration and some needs source code modification.  To disable other serial ports you need to modify source code file /arch/arm/mach-at91/board-sam9260ek.c in function static void __init ek_map_io(void).  Just comment out the lines that configures the USART ports that you don't need.  In the kernel configuration you need to go through all the sections and disable all the features such as SPI, I2C, SD card, sound, etc.
