Hello,

I need to update my router's firmware. It's a x86 geode  with the Chaos Chalmer version installed. I'm trying to execute this command:

 sysupgrade -v /tmp/firmware.img

But it doesn't install the new image. Here is the log:

etc/sysctl.conf
etc/sysupgrade.conf
Sending TERM to remaining processes ... logd rpcd netifd odhcpd authserver collector gpsd uhttpd monit dansguardian dnsmasq ntpd dansguardian dansguardian luci ubusd askfirst 
Sending KILL to remaining processes ... askfirst K90network sleep 
Switching to ramdisk...
Terminated

I'm using this command to drop the caches and free up RAM:

 echo 3 > /proc/sys/vm/drop_caches

Does anybody knows what is the problem? I  can use only commands, not LuCI.

Any tip will be very helpful,
Thanks.
