Hello All ... Got my Turing Pi 2 the other day. Been waiting for this moment since before the fall of modern civilization. I bought a nice Mini ITX case and a power supply. I wired everything up. Put heat sinks on the Raspberry Pi CM4 modules and slotted them righteously. I wired the Front IO panel appropriately. Plugged it all in, turned it on. And nothing. The NODE1 (amber colored) Power Light comes on, flashes a couple of times, then stops. The green light beside the 24-pin ATX Power Supply is on. I've got the unit connected to a monitor via HDMI cable. Turn it on, blink blink blink, then nothing. Call me crazy, but it's supposed to do more than this, yes? I'm not entirely sure what to do next. Is there a Magic Incantation I failed to recite? Any suggestions would be welcome. Sincerely ... StephenStrangeWare

did you power up the nodes? Also, do you have the CM4s flashed already or are you going to flash it through the TPi2?

Did you put the CR2032 battery in? If yes, remove it

It is ALIVE !!!

Questions: I did not put the CR2032 battery in. I'm having a little difficulty figuring out how to open that door without breaking it off. Is the CR2032 battery necessary? Next, is a Network Connection necessary?

The battery, in general, is not necessary. To be honest, you probably won't see a difference since the correct BMC time is not really exposed anywhere besides it's logs

I saw a mention of the RTX Battery Bug. So I'll forego the battery for now.

So a few links: - the issue: https://www.kickstarter.com/projects/turingpi/turing-pi-cluster-board/posts/3725544 - more info: https://www.kickstarter.com/projects/turingpi/turing-pi-cluster-board/posts/3749134 - the fix: https://www.kickstarter.com/projects/turingpi/turing-pi-cluster-board/posts/3765599

I unplugged the Front IO cable from the panel thinking maybe faulty wiring was the reason it didn't power up. Will wiring the Front IO panel spare me from having to hit the KEY1 button to power everything up?

key1

and power button on the front panel do exactly the same thing, you can use any

Can you refer me to a definitive "How to interact with the Turing Pi 2 and the CM4 modules installed therein" guide?

There are the help pages to look at probably: https://help.turingpi.com/hc/en-us

Awesome, thanks ... Lastly, I can't get any response from keyboard or mouse. I have two keyboards, one that's USB wired, another (along with the mouse) that's Logitech USB dongle connected. I can't get any response from either keyboard or mouse connection. Is there something (additionally) that I'm overlooking?

What are you trying to do? Where are you connecting them and what is your expectation?

I connected the wired keyboard to one of the USB ports on the Turing Pi 2 board. I'm being prompted to log into one of the Operating Systems I loaded on one of the CM4s. But it isn't accepting input. I tried to use the USB Dongle connection for keyboard and mouse, from the on-board USB connector. No dice this far.

Ok, so there are 2 types of USb ports at the back

Yes, kind of. I'm a little behind on the details and making assumptions that aren't quite panning out. Does the Getting Started Guide walk me through the USB details you spoke of? Particularly, the "Remember the command to put the USB mode into the device mode? Set it to host to given node and connect the device" bit. Suffice it to say, I'm not up on those details quite yet. I need to know how to traverse nodes and use the white USB keyboard connection.

The docs explain this. Also, you don't have to use commands, you can use the web panel to set the USB mode and which node it is connected to.

The Web Panel? Awesome. The docs explain this too, yes?

There are no silly questions, just silly answers 😉

The Web Panel is the BMC Web Interface, yes?

Yes, correct

Great, thanks a bunch. You've been inordinately helpful.

Happy to help 🙂

Do changes made via the Web Panel take place immediately, or do they require a restart?

They do take place immediately

And the two blue USB plugs on the Turing Pi 2 board are associated with Node 4, correct?

Yes, along with a USB 3.0 connector on the board (for the front panel)

How about HDMI? When I power everything up, I see a logon for Ubuntu Linux, which I loaded a while ago on one of the CM4s. How do I determine which CM4 I'm looking at here?

It's node 1

Thought so. The diagram looks like it's going to GPIO so I wasn't sure

Well, this is kind of unfortunate indeed. With Jetson modules, which cannot use this USB port in a host mode (because of the Jetson module design), I used a Mini PCie USB controller

If a Mini PCie USB controller will allow me to interact directly (rather than headlessly) when the need arises, I'll get one. But right now, I want to interact directly. Will a MiniPCIe USB controller allow me to interact directly via mouse and keyboard? Headless is great, but initially, direct is kinda necessary in my experience with these devices.

The thing about the headless part is that only Node 1 has a HDMI and the idea is the Node 1 might be indeed a main node to control the whole cluster

Without destroying the device?

I would rather not use torches 😛

You're saying the PCIe card needs to be desoldered?

Yeah, that'l make for a very crisp TP2 board

A standoff

That's one of the bridges I had intended to cross eventually. But maybe I'll focus on headless.

This way:

The one I bought I did not remove the standoff and it worked with Orin 😮

Maybe, LOL 😄

... do you happen to know whether the common ASM1061-based Mini-PCIe to 2xSATA boards tend to be half-length, or whether they also need the standoff removed?

They're half-length

Thanks! 🙂

Greetings ...
