I was referred to this list as I am interested in extending the kind of support that I am used to with SC200 based systems to the systems supported by OpenWrt such as the Netgear WGT634U which is built around a Broadcomm BCM947XX chip. In the bcm947xx arch directory on OpenWrt (and I am not quite sure how it got there) there is some code (marked as copyright Broadcomm) which talks about Watchdog functionality, but does not seem to link it into the rest of the linux watchdog functionality which Alan Cox seems to have either written or rewritten. There is a /dev/watchdog that is used by a watchdog daemon (in the OpenWrt case this would be the BusyBox watchdog function) to refresh the watchdog and stop the box rebooting itself. Does anyone know anything about watchdog functionality in the Broadcomm chips, or about the code that Broadcomm seem to have written for it and how to use it? Thanks in advance David
