Why is there a problem while installing udev ?
Installing udev on the kurobox debian will lead to a problem with AVR device initialisation (and if you do not initialise the AVR device, the kurobox will shut down few minutes after power up) !
The problem is that the AVR device can be accessed using /dev/AVR00, but udev will not create this device ! You have to use /dev/ttyS1 instead ! The problem is that when you're not running udev, /dev/ttyS1 does not point to the AVR device !
How to solve the problem
To solve this, you have to update the following files :
- /etc/init.d/halt :
replace
echo -n "EEEE" > /dev/AVR00
with
if [ -e /dev/AVR00 ]; then echo -n "EEEE" > /dev/AVR00 else echo -n "EEEE" > /dev/ttyS1 fi
- /etc/init.d/reboot :
replace
echo -n "EEEE" > /dev/AVR00
with
if [ -e /dev/AVR00 ]; then echo -n "EEEE" > /dev/AVR00 else echo -n "EEEE" > /dev/ttyS1 fi
- /etc/init.d/kuro_boot :
replace
echo -n "AVR00 port init : " stty -F /dev/AVR00 10:1:9f0d:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0 echo -n "AVR init string send" echo -n "AAAAFFFFJJJJ>>>>VVVV>>>>ZZZZVVVVKKKK" > /dev/AVR00
with
if [ -e /dev/AVR00 ]; then echo -n "AVR00 port init : " stty -F /dev/AVR00 10:1:9f0d:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0 echo -n "AVR init string send" echo -n "AAAAFFFFJJJJ>>>>VVVV>>>>ZZZZVVVVKKKK" > /dev/AVR00 else echo -n "ttyS1 port init : " stty -F /dev/ttyS1 10:1:9f0d:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0 echo -n "AVR init string send" echo -n "AAAAFFFFJJJJ>>>>VVVV>>>>ZZZZVVVVKKKK" > /dev/ttyS1 fi
- /etc/init.d/kuroevtd (If you're not willing to install avr_evtd instead of kuroevtd)
replace both entries (in start & restart) of
start-stop-daemon --start --quiet --exec /usr/sbin/kuroevtd /dev/AVR00
with
if [ -e /dev/AVR00 ]; then start-stop-daemon --start --quiet --exec /usr/sbin/kuroevtd /dev/AVR00 else start-stop-daemon --start --quiet --exec /usr/sbin/kuroevtd /dev/ttyS1 fi
Conclusion
Now you can make a
apt-get install udev
and the kurobox will no more shutdown few minutes after startup !
