If you’re starting afresh, the following two links could be of use to you.

  1. https://github.com/ttn-zh/ic880a-gateway/wiki
  2. https://youtu.be/np4rIQ_teR4
    The first link is about configuring the gateway (plz discard the TTN portion unless you want to go for it), whereas the second one is about installing the loraserver on gateway, which is what you’re looking for. However the hardware used in the second resource is different, so the procedure might differ. Also you might have to refer to some of the other videos in the video series of the latter author, for better clarity on certain aspects (especially config files in video numbers 28 and 28.1 of the series https://www.youtube.com/playlist?list=PLmL13yqb6OxdeOi97EvI8QeO8o-PqeQ0g). Hope this helps.

Even I’m looking for some help on gateway OS image files appropriate for imst. The image folder has many files, and I’m not able decide which one should I go for.

You should download the latest sdcard image, see https://www.chirpstack.io/gateway-os/install/raspberrypi/ for Raspberry Pi instructions. After that, follow these instructions: https://www.chirpstack.io/gateway-os/use/getting-started/.

The thing is, with the iMST iC880A shield there are many pin options possible, this might depend on the instructions you are following or on the kit you are using.

From what I know, the IMST Gateway has it’s reset PIN not on PIN 25 but PIN 5

When using this: https://github.com/ttn-zh/ic880a-gateway/tree/spi

Tow changes are needed to run the packet forwarder on the IMST Lite GW:

#echo "$SX1301_RESET_BCM_PIN"  > /sys/class/gpio/unexport

This information is 2 years old when I first worked with the gateway. But maybe it helps with the setup. A tested tutorial how to use Chiprpstack OS on the IMST Lite GW would be very nice. I have not tested it but expect to run into Pin Configuration issues.
