Hi all,
Hi Zhou Yu,
I want to add a interrupt for AT91SAM9260EK board. When I defineCONFIG_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.
It is there BECAUSE the current source for AT91 does NOT support interrupts...
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!
It requires more than commenting the message out :)
You have add interrupt handling (write source) to AT91 in general and provide a patch for that.
But first you have to define why you need interrupts (in the u-boot phase) in the first place.
Best Regards Reinhard
