Auto Power Recovery DNS-320

[d.i.saunders]

Hi All,

Think this may have been asked before...But I am a little unclear on the response..

The stock firmware allowed recovery from a power failure.. This happened if the device was on or if it was off at the time..(correct me if im wrong) A break, and then restoring the power caused the device to boot up..

In my testing of ALT-F it seem to work on if the device is power on. So if power is broken and restored while the device off it will not cause it to boot up..

I saw this post, and assume this relates to adding recovery options when the device is active.

Are there any setting that can be edited on power options? Is my memory correct on the stock version ? Any way to add this or access this on the Alft-f

Re: [Alt-F] Re: DNS-320 and DNS-325

Here there is also an updated version of the patch that adds support for reset button and power recovery.

Many thanks

Please see related ticket 32 

All those options are model and HW rev level dependent, and only by reverse engineering it is possible to replicate that under Alt-F.

Some people, Lentin, Böhler, et al, have partly done that job on some boxes, and I have included their findings in Alt-F, but I don't feel inclined to investigate for compatibility with other boxes models of dig for more.

Alt-F is open source and community driven, so if someone discovers how to implement those features, please describe how to implement them or, preferably, submit a code patch. I will be happy to help.

The current tweaks I remember:

/etc/init.d/rcS:

# Tell PMU to turn back on after a power failure 

# From http://jamie.lentin.co.uk/devices/dlink-dns325/userland-configuration/

if test $board = "DNS-320-Ax" -o $board = "DNS-325-Ax"; then

Thanks for the reply.. I will take a look at the link as try it on my device..

Also noticed that it now only uses 4w when in standby... Might just leave it at that..

I know that this is an ancient thread, but I had the same problem. Maybe if you remember if this worked?

I tried to manually give the commands, then forced a power cycle, but the machine didn't boot up.

Did it finally worked for you? Did you try?

Thank you
