Hi to all, My iC880a has arrived today and I tried to setting up my gateway according to instructions from the TTN. I also added remote config file according to my gateway MAC address into github. But when I start my gateway it does not appear on gateway status ( http://staging.thethingsnetwork.org/…

Hey, thanks for getting back so quick. I ran build-pi.sh , which brough lora_gateway and another copy of packet_forwarder into packet_forwarder/mp_pkt_fwd . Running make in the new lora_gateway directory gives a similar error: make all -e -C libloragw make[1]: Entering directory '/home/pi/kersing/p…

I needed sudo to build the folders in /opt. Thank you for making this repo. I’ll let you know if I hit any more speedbumps.

@kersing I was able to build it, and now I’m getting the error which is the title of this thread. 10:26:41 *** Multi Protocol Packet Forwarder for Lora Gateway *** Version: 3.0.20 10:26:41 *** Lora concentrator HAL library version info *** Version: 5.0.1; Options: native; *** 10:26:41 INFO: Litt…

The solution is part of the thread as well. Fix the clock setting, make sure the right reset pin is used and allow for a couple of retries. If that all fails use the command line switch to set SPI comms to a lower speed.

Sorry, I couldn’t find any post about changing the clock setting. Where do I set that? I have changed the reset pin to 7, which should be right.

Ah, thank you. Still confused as to what I should set SPI_SPEED to. I saw some info about that here: https://github.com/Lora-net/lora_gateway/issues/26 , but none have worked. I’ve experimented with many different SPI_SPEED values in /opt/ttn-gateway/dev/lora_gateway/libloragw/inc/imst_rpi.h, between…

Mp forwarder allows you to specify the SPI speed on the command line (-s ). Have you locked the clock speed of the RPi3? What do you use to reset the concentrator?

I’ve tried that method, too. No, I couldn’t figure out how to do that. Overclocking options are disabled on the Pi 3.

Locking the clock requires setting core_freq as mentioned in the message I linked to. Google helps as well…

Also, make sure to have SPI enabled (You wouldn’t be the first to forget that step)
