rpi watchdog

gistfile1.txt

From this: https://github.com/raspberrypi/linux/issues/1285#issuecomment-182264729

That is, add:

dtparam=watchdog=on
to the end of /boot/config.txt

$ ls -l /dev/wat*
crw------- 1 root root  10, 130 May 20 01:28 /dev/watchdog
crw------- 1 root root 253,   0 May 20 01:28 /dev/watchdog0

hay que agregar sudo a la llamada a la app porque sino no hay permisos para escribit el watchdog

sudo nano /etc/profile

también subir el volumen [comprobar]

amixer set PCM -- 100%

goes off screen, and negative if there is too much border

#overscan_left=16
#overscan_right=16

overscan.
