Jetson Nano (again) - use in headless mode?
Recap - Nano won't produce a picture on HDMI device (it used to, but the video was inverted, and picture shifted to the left, anyway, so not entirely useful)...
After my last posting, following a suggestion that the board may have misconfigured itelf, I said I was going to re-flash the SD card, connect a keyboard and a mouse, and try again... follwing that, I was going to flash a 'headless mode' version of the software into it, and see if I could talk to it via the USB port of my computer...
I have now tried the first option, with no luck, so am wrestling with headless mode... I don't understand how it works - im just trying to follow th instructions on NVidia's website, wich say:
1) Unfold the paper stand and place inside the developer kit box.
2) Set the developer kit on top of the paper stand.
3) Insert the microSD card (with system image already written to it) into the slot on the underside of the Jetson Nano module.
4) Insert the 2-pin jumper across the 2-pin connector, J48, located next to the MIPI CSI camera connector. This enables the DC barrel power supply.
5) Connect your DC barrel jack power supply (5V/4A). The Jetson Nano Developer Kit will power on and boot automatically.
6) A green LED next to the Micro-USB connector will light as soon as the developer kit powers on. Wait about 30 seconds. Then connect the USB cable from the Micro USB port on the Jetson Nano Developer Kit to the USB port on your computer.
It then says that a server should be running on the Nano, which will allow you to login:
"Open the following link address : 192.168.55.1:8888 - The JupyterLab server running on the Jetson Nano will open up with a login prompt the first time."
I'm confused as to how the connection is established - should there not also be something that has to be unning on the local computer to tell it how to map the IP address and port that you enter into the browser, to a USB port?
I have tried exactly what it says on the website on both a W8.1 and a MacOS (old.. probably Lion, 10.7.1) and got timeouts on both.
Am I missing something, or is the Nano really now dead as a dead thing?
The green LED comes on when power is applied - the heatsink gets luke warm, too - and caps lock (etc) LEDs and mouse LEDs work OK. i have poked around the board wth a DMM, and the supply looks to be holding upat 5.2V; there is also a respectable 3.3V present in various places around the board.
EDIT: I meant to add a question: has anyone on here sucessfully downloaded and installed the headless mode software:
