not sure how to debug if there is no console…
Is there any UART port in your FX30?
You can write a script in module and check if it can ping outside, if no, then it can self reset
I can write a script to ping outside, I don’t want to reboot, I want to find a problem and fix it
And I’m trying to get an answer where to look and look for what ?
You need to look for a console port to understand the problem
Is there any UART port in your FX30?
Before problem happens, you can ssh via ethernet or via USB ECM.
But after problem happens, you cannot ssh via either of the interface.
you might need to capture wireshark log to see what is happening in lower layer.
How do I know if there is an UART port in my FX30 ?
there is no tcpdump in FX30, May be there is a version of tcpdump compiled for FX30 ?
you can have a look in the hardware if there is an UART port
For tcpdump, you can see here:
Thank you, will try tcpdump tomorrow
BTW, before problem happens, there should be some LED lighting in the ethernet port.
After problem happens, did you still see those flash LED?
I’ll check, I don’t remember.
Ok, thank you for tcpdump, it can be very helpful.
I see that both “emc0” and “eth0” are disconnected after some time, but only “emc0” is dead I can reconnect on “eth0”, this is good enough for me for now.
So we can probably stop debugging for now, I can return to this if I see dead “eth0” connection in the future. Thank you!
