Anyone know how the error-led could be toggled via "bash" in Linux with the
above information ?
For the net5501, using GPIO, (Linux 2.6.35) we use...
--
errorled_net5501()
{
local GPIO=6 sys_gpio="/sys/class/gpio" value
case $1 in
off|low|0) value=0 ;;
*) value=1 ;;
esac
if [ -e "${sys_gpio}/export" ]; then
echo $GPIO > "${sys_gpio}/export"
echo "out" > "${sys_gpio}/GPIO${GPIO}/direction"
echo $value > "${sys_gpio}/GPIO${GPIO}/value"
echo $GPIO > "${sys_gpio}/unexport"
else
echo "errorled_net5501: No '${sys_gpio}/export' exixts." >&2
fi
}
--
but it doesn't appear that the net6501 supports the error-led off of GPIO.
