Hi Dan. At the risk of sounding like a real dummy (which, when it comes to terminal and lots of other things, I am), I’m giving this a go right now and terminal is returning: zsh: bad pattern: /dev/tty.usb[tab
-The rpi is connected to my computer via USB at the pi’s USB mini port and is powered on
-I’m entering this exact text, which is probably wrong: screen /dev/tty.usb[TAB KEY] 115200
-I had pizza for dinner
-This is the end of the list
sorry, i realized that i don’t totally understand what you’re trying to do. i assumed you were using some additional hardware to connect to the UART pins on the raspi. but reading again it sounds like you’re trying to power the pi from your host computer USB (not a good idea in itself) and also use that usb connection for communcation (which won’t work.) i’d recommend searching on the raspi fora / docs on how raspi UART works if you need it.
the instructions you reference are for installing an upgraded compute module on factory norns, which includes a dedicated serial-miniUSB adapter on the PC board.
if you just need to login to the pi for troubleshooting network (or whatever), the easiest way is to just attach an HDMI monitor and USB keyboard.
if networking is set up, and you can shell in with ssh, you can access raspi-config that way to expand the filesystem or whatever
That’s what I tried first, and I got as far as being asked for the password in terminal. I tried “sleep” and “nnnnnnnn” and neither worked. But also, was at the end of a very long day, and sounds like I just need to poke around a bit more. I assume there’s a Dummies guide to all of this somewhere online. Will report back if I have success. Thanks guys.
So I think the (embarrassing, albeit honest) reality here is that I don’t know how to SSH into norns.
The docs take this knowledge for granted, and maybe that’s fair. Apologies for the hand holding.
I’m entering ssh IP.IP.I.P in Terminal on my Mac running Catalina (but, like, the IP address listed under "wifi: on norns. Terminal then asks for the password. There’s an icon of a key, and I can’t see what I type from that point forward. But I’ve tried “sleep”, “nnnnnnnn” and “raspberry”.
There’s some info regarding ssh access that suggests altering the root image, but I’m assuming this is moot since the norns image is much different than Raspbian, et al.
Anyway, let me know if what I’m doing is way off base. And pretend you’re talking to someone who is technically proficient in the meat world but inexperienced with terminal/coding/etc.
