Hello World Timeout in Remote Console

Embedded Devices Linux
#1

I’m just getting started with Digi ESP and Linux. I’ve managed to build and launch the simple hello world application which prints hello world to the terminal 10 times, HOWEVER, after 5 seconds the Remote Console Tab says ‘Disconnected@192.168.0.112[hello_world_c]hello_world_c’ and stops. What happened? I’m looking for a timeout setting somewhere but can’t seem to find it help!

I tried the gpio sample with the same result - it seems that the application stops on the target - disconnected at the target?

Thanks!

its because your main() is returning to kernel.

relpace “return;” with " while(1); "
you can find the difference

That makes sense, but alas, same result. My code is below. Is there a configuration file somewhere on the target that needs to be modified?

Thanks for your help!

ahh… thats weird.
for me it remain “connected” …

btw which hardware are you using?
and whats your Digi ESP version?

try to initiate a telnet connection to the target.
what is happenig when you say “RUN” is ::

It is transfering the application binary via FTP to the module, than launches a telnet session to start it.
