One conduit working, another one doesnt

[Amit Bhatia]

Hi, I have two conduit. One of them is working with the mDot nodes. While the other one which was working, has now stopped working.

I see the error log even though I did not enable the Packet forwarders, still I see these Error log writing. Does any one know what these are?

Looks like the packet forwarder is not able to start.

Try to run the packet forwarder alone and provide the output.
# /etc/init.d/lora-network-server stop
# cd /var/run/lora/1/
# ./lora_pkt_fwd

Provide output of hardware info
# mts-io-sysfs show lora/*

Looks like lora-network-server is not starting…

Here is the info you requested

Try these commands to reset the card and reload the fpga firmware.
If cdone does not change when creset is unset then there is an issue with the lora card.

# mts-io-sysfs store lora/creset 0

# mts-io-sysfs show lora/creset
# mts-io-sysfs show lora/cdone

# mts-io-sysfs store lora/creset 1

# mts-io-sysfs store lora/reset 0

# mts-io-sysfs show lora/reset

# mts-io-sysfs store lora/reset 1

[Amit Bhatia]

cdone remains as 1. does that mean LoRA card is not working?

root@mtcdt:~# mts-io-sysfs store lora/creset 0
root@mtcdt:~# mts-io-sysfs show lora/creset
0
root@mtcdt:~# mts-io-sysfs show lora/cdone
1
root@mtcdt:~# mts-io-sysfs store lora/creset 1
root@mtcdt:~# mts-io-sysfs store lora/reset 0
root@mtcdt:~# mts-io-sysfs show lora/reset

root@mtcdt:~# mts-io-sysfs store lora/reset 1

Yes the lora card is not in working order.
Perhaps a component was accidentally knocked off when installing the card?

You could carefully remove the card and look for damaged components.
