This IRQ storm is very likely what bites you. The GPIO IRQ does not seem to be properly masked upon arrival, or maybe re-enabled too early,
Hi, thanks for the helpful explanation. Together with hint from
http://blackfin.uclinux.org/gf/forummessage/96808
this lead me to comment out the check for the interrupt trigger type in mach-common/ints_priority.c:bfin_gpio_mask_ack_irq so that set_gpio_data(gpionr, 0) is called in any case. At least, that helps so that my system doesn't freeze and I can read "keyboard" events generated by gpio-keys from /dev/input/event0 Kolja _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
