Let me start by saying this isn’t the first time I’ve run into this problem.
My older post initially described the issues I was having with it:
https://devtalk.nvidia.com/default/topic/1027414/jetson-tx2/cannot-setup-wlan0/post/5267974/
I’ve also read all related posts I could find here on devtalk:
https://devtalk.nvidia.com/default/topic/1026996/jetson-tx2/setting-up-wi-fi-acess-point-on-tx2-/
https://devtalk.nvidia.com/default/topic/1031924/jetson-tx2/how-to-set-up-wifi-during-jetpack-installation-on-a-headless-tx2-/
https://devtalk.nvidia.com/default/topic/910608/setting-up-wifi-access-point-on-tx1
And I’ve followed the instructions to the letter, but to no avail.
This is from the boot-up sequence (before I even log in to try bringing up the AP):

I’ve setup hostapd and interfaces as well as enable the bcmdhd module:

The annoying thing is that NetworkManager under Gnome seems to be able to bring the Wifi up, but since I only use SSH, this is turning into a big problem.
I’ve setup a new hotspot connection via NetworkManager and it doesn’t complain at all.
Problem is, I don’t see the network and any attempt to connect to it fails.
Turning it off from Gnome/NetworkManager produces:

Turning it back on again (after allowing NetworkManager to manage eth0 and wlan0) produces a similar error:

Can anybody please help?
Please don’t tell me to flash the newest JetPack, this is part of a prototype to be trial-tested and we cannot afford the time to set-it up again on the premise it might work with a newer JetPack.
