The avr-evtd daemon is aimed at the Buffalo series of Linkstation and
Kurobox. This replaces the existing ppc_uartd daemon. The daemon
configures the AVR and provides the necessary 'keep-alives' to the AVR
watchdog timer.
The daemon also checks that the /mnt and / filesystems are within scope
(disk space remaining) and also monitors the power button and the 'red'
reset button. These button events are turned into requests into the
EventScript. This allows a user to control what occurs (system wise) when
an event is received. The same script is also used by the timer shutdown
process.
Linkstation or equivalent. Either stock or custom kernel and either standard or Debian distribution.
If you have the GCC tools installed, rebuild and install the process by typing:
make
make install
Remove the current start and shutdown symbolic links for the
ppc_uartd:
update-rc.d -f ppc_uartd remove
Create the new symbolic links:
update-rc.d avr-evtd start 12 2 . stop 95 0 6 .
This daemon can use either the existing melco provided files or a custom
configuration file. This custom file should exist within the /etc/default
directory. Just edit the sample file contained there and move:
mv avr-evtd.sample avr-evtd
The Linkstation and Kuro communities.
None known, but there are probably issues with the code, as it has survived changes in the maintenance.
It has been tested on Kuroboxes with PowerPC processors, Linux 2.6, and Debian as the distribution. Reports of bugs are welcome.

Following major changes with the daemon and the support scripts, some of the functions of the reset and power buttons have been changed. These mostly affect the reset button. The reset feature has been removed (as power button can perform this feature) and instead this can be used to selected EM-Mode (HDD diaster recovery feature of the LS/Kuro). If the reset button is held for at least 20 seconds then a message is written to the flash memory and a reboot is issued. At this point, the box is now in EM-Mode as it has booted from ram flash and not HDD image.
PLEASE NOTE, THIS IS FOR USE ONLY BY THOSE WHO ARE AWARE OF THE ISSUES OF ENTERING EM-MODE. DO NOT USE OTHERWISE YOUR HDD DATA IS AT RISK.
