I've got the latest hardware (rpi 3b+) and am trying to get a flavor (ev3dev) to run on it. However, it never connects to the network - either ethernet or wifi.
I looked into how I could capture the startup logs, and bootlogd seemed like what I needed. However, I'm unsure how to set that up, if I can't connect to the pi to set it up, very much a catch-22.
Is there any way to modify the image after flashing, like how I can add the wifi config file manually via the flashed card's OSX mounted image? Could I drop off a precompiled bootlogd in the right folder that would get picked up before bootup so I capture whatever is failing with the networking?
Or is there already a log file I could load from the SD card?
I hope it isn't an incompatibility - the ev3dev build is from before the 3B plus was released, but AFAIK nothing major changed in the network layer, right?
