Hi,

Is it possible to reboot the microcontroller via a lua script without reboot the HAH?

 

Thanks,

 

Garry

Rebooting the AVR without the rebooting the HAH

I suspect you want to do this because the URF isn't stable... well I've been working with Karl on fixing this and we are almost there - things are on hold whilst I'm moving.  Karl can tell you about our progress...

Technically might possible caveat I've not tried the script below

echo "reboot" >/dev/console
sleep 1
echo "+++" >/dev/console

The sleep and the +++ echo are IMPORTANT due to the way in which the AVR firmware works.

thanks... good news

Thanks for the update Brett, good to hear your getting some help with the project.

I will give the code you suggest a go, was thinking I would try to get around the RF issue with a microcom reboot whilst leaving plugboard running.

Grateful for your time, as always. Cheers,

Garry.

Works with slight modification

Brett,

 

Code works great, just needed a slight tweak to stop LUA bugging out.

here is what I come up with:

local cmda = string.format("echo 'reboot' >/dev/console")
local cmdb = string.format("sleep 1")
local cmdc = string.format("echo '+++' >/dev/console")

os.execute(cmda)
os.execute(cmdb)
os.execute(cmdc)

That's one way

When you progress to LUA master you would write something like this

os.execute[[
echo reboot >/dev/console
sleep 1
echo +++ >/dev/console
]]

much nicer :)
