Hi, I have an issue with a device I'm developing. If I run it at this way, I haven't any trouble:

/usr/pluto/bin SmartEPG -d 50

When I send a message to device, is working properly. But, if I reload DCERouter, when I send a message to device, it dies:

========== NEW LOG SECTION ==========
1   04/06/10 18:05:33   50 (spawning-device)   Starting... 6
1   04/06/10 18:05:33   50 (spawning-device)   Found /usr/pluto/bin/SmartEPG
Return code: 139
3   04/06/10 18:06:21   50 (spawning-device)   Device died... count=6/50 dev=50

Anybody knows something about this?

Thanks!  Wink

looks like you need to run the device through the gdb debugger.

--> At this point, I send a command from the admin website to device.

Need to implement command #1076 - ChannelUpdate
Parm #264 - Channel=La 2
Parm #286 - Show=Desafio Champions
Checking online users...
generating XML...

It works fine, generates the XML file... but only if I run the device from console, if I let LMCE to running the device himself, doesn't work.

By the way, I'm running Python scripts from the device.

hmmm, how about running gdb against one of the coredumps in /usr/pluto/coredump ?

Another question... who launches the devices? Root? My desktop user?
