Dear all: I am using uclinux-2.4.19, I wanna to use hardware scan to implement my keyboard driver. So I need to register a interrupt use request_irq. I have 14 interrupts, and using 8/13 for eth0/1, 6 for serial, 11 for timer. ========= # /mnt/nfs-server/busybox cat /proc/interrupts CPU0 6: 689 imj_irq serial 8: 147 imj_irq eth0 11: 3759 imj_irq timer 13: 0 imj_irq eth1
ERR: 0 ========= At first, I register IRQ_12 for keypad, and do some keypad_scan_enable_command. But, I didn't get any response when I pressed a key. So, according as CPU spec, I register IRQ_4 to my keyboad interrupt, and do the same keypad_scan_enable_command. But, when I pressed a key, system collapse----cann't do anything by console and ping command have no response. Does this means that the IRQ_4 is arised ? If the answer is "yes", why does the system collapse happens? Additionally, why IRQ_12 can't response when key pressed? _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
