[U-Boot] How can i add intterrupt for AT91SAM9260EK board

Hi all,

I want to add a interrupt for AT91SAM9260EK board. When I define CONFIG_USE_IRQ in at91sam9260ek.h, then compile, I got error message "error: CONFIG_USE_IRQ not supported". I don't know why put this message here so I commented out.

Then I define CONFIG_STACKSIZE_IRQ, CONFIG_STACKSIZE_FIQ like this, and compile complete. #define CONFIG_STACKSIZE_IRQ 4096 #define CONFIG_STACKSIZE_FIQ 4096

Download u-boot.bin to my board with sam-ba.exe, and reset. When u-boot run to enable_interrupts() in board.c, the board halt.

What should I do? Thank you! BTW: Hardware has been verified is good.
