I got my 811_915 a few weeks ago… it was pretty simple to setup, I just grabbed the open source project, installed coocox ide, and loaded it up… then modified the project to compile for AU LoraWAN and it was up and running.
Having to go back and dig into the gateway setup to realise that the github project which looks like it would autoconfig everything I needed but didn’t actually set my frequency plan was probably my biggest hiccup in the whole setup and test project (well, also my original install on the pi somehow stopped saving changes to the SDcard… that was annoying, and just disappeared when I did a second install on a new SDcard)
I did have a go at connecting my jlink, pretty straightforward, but I think the last time I compiled code and programmed it in I just sued the serial bootloader because it was easier and I wasn’t worried about being able to debug.
PS, as far as the JLINK connection list above goes, yes you’re right. But leave SWO alone at least to start. It’s optional (for “realtime” streaming debug out) and additional to the base functionality you get with SWD
