Abort barebox booting and enter the console. the board reboots immediately when I press the button without release. here is my .dts about this button: net { label = "board:LED1:system"; gpios = <&gpio 1 GPIO_ACTIVE_LOW>; default-state = "off"; barebox,default-trigger = "net"; };Copy-paste mistake?2. Panic. type 'go 888' make barebox panic. now I really need a 'reset' key. I press and releaes the key, and try to hold this key several seconds. no reaction. Is the 'reset' key designed for reset the board when something goes wrong?That's the watchdog's job. If your hardware features a hardware watchdog, you can have it started on bootm or configure barebox' poller to feed it continuously. If barebox panics or anything else happens before Linux starts feeding the watchdog, your system will then automatically reset. You could have barebox panic loop on a gpio, but it would only help if barebox actually calls panic. If you run into an infinite loop, or the exception vectors are overwritten, there's nothing barebox can do (short of evolving to barebOS and implementing preemption and privilege separation).
May be it would make sense to have an option simila to the kernel, to reboot on panic. -- Regards, Oleksij _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
