i shutdown master node on TP 1 with command sudo i2cset -m 0x02 -y 1 0x57 0xf2 0x00 Im not expirienced in I2C and i got RPI4 on side. Need some help with wireing RPi4 to TP 1 and commands. All help is most welcome

Given that we should be starting to see the TPi2 in our hands soon what would people like to see changed in the original design IF WE EVER got a TPi V2.1 (Please no comments about the RTC issue that goes without saying) Please be positive in the community spirit some ideas I would like to see would be, The movement of header ports (Power Connector, SATA, USB3 header) away from the front of the broad preferably to the side to aid airflow though the cards installed Dedicated USB header for the CM4 Mode port (I could see this of more use on the front of a case) Move the reset BMC buttons onto the Back plate at right angle to the broad for easier access from the rear of the case Maybe an ATX version with 6 or 8 nodes? PWM fan for system fan (Maybe two instead of 1) Maybe also add PWM for the nodes also (Forgot that thanks @segabor ) Upgraded Ethernet 2.5gb maybe useful depending on the use case, I would expect that would almost allow Max throughput of all connected broads currently Maybe mPCIe that supports SPI for LORWAN gateways (though not sure how this might be achieved perhaps some small jumper switch) POE class 4

I finally finished and exported the 3D-printable PC case PSU covers for these of you who do not use standard PSU and want to cover the PSU hole. Links: - Printables: https://www.printables.com/model/435941-pc-case-psu-cover - Thingiverse: https://www.thingiverse.com/thing:5937310 I exported 3 different variants with a possibility to create more in the future. The variants utilize small and big mesh, FAN grill and PicoPSU socket hole in different combinations. The FAN screws are prepared for standard FAN screws and are threaded. The PC case screw hole are threaded as well. The variants include:

PSU_cover - [01] blank
PSU_cover - [02] blank with PicoPSU
PSU_cover - [03] small partial mesh
PSU_cover - [04] small partial mesh with PicoPSU

Now that the kickstarter shipments have resumed, are we going to restart sending them out in blocks are before they stopped shipping. just trying to get an idea of how much longer it will be before I see the board. I've gone thru the order update process, but it is still processing .. Thanks team

I’ve got CM4 no eMCC and want to boot from microSD. Probably will mount a separate home partition from SATA SSD. What speed etc. does the microSD slot on the CM4 adapter support? What specs should I be looking in a microSD for optimal boot drive performance and durability? What brands are recommended for high reliability?

Does Turing Pi 2 board work these modules? - https://pine64.com/product/sopine-a64-compute-module/ - https://pine64.com/product/soedge-ai-neural-module/

This to discuss about the 4 JST connectors next to each node.

I have 3 cm4s with 8GB emmc. I flashed the first one to raspbian just to try and it all works great. I have done the other 2 with dietpi and would like to reflash the first one to dietpi. I cannot get the emmc to mount or have rpiboot detect it. I have set the usb 2 port to node 1 (the node I want to reflash) and it is not detected. Does anyone know what the problem is here? This is on a Turing Pi V2 with the latest firmware.

I just received my TP2 today! Unfortunately I can't seem to locate any compute modules to put in it. Any advice on a strategy for locating a CM4? Any idea when the RK1s will be available?

I'm very fearful of bricking my board by soldering the resistance to the board. The blog post mention the resistance is needed to prevent a clock drift. I was thinking of just run it with the battery pcb and setup a NTP to clock syncing. My understanding would be that the drift would only happen during reboot. Am i right?

Hello there, I mentioned this in chat, but I think this is likely the better venue. I opened my Turing Pi 2, plugged in the pico power supply, an HDMI cord, and an ethernet cable, but am not seeing any signal for the HDMI. I've verified the cable is good, but I can't seem to get a signal. I read that SSH is disabled by default, so I can't get in to change anything. How can I fix this?

Really excited for this delivery. Unfortunately it’s useless because I cannot get any raspberry pi modules. I’m OK holding out for the  RK1 Compute Module, but I have a feeling it’s going to be the same thing. Is anyone having luck getting modules that are reasonably priced?

I created a Turing Pi 2 tray that lifts the board up and makes enough space for the M.2 drives (without heatsinks). It's designed for M3 3.0-5.0 mm flat head screws. This base will be later further expanded to a full bench that lifts the board even more up, lets you mount 2 2.5" drives and manage cables Links: - Printables: https://www.printables.com/model/451245-mini-itx-tray-for-turing-pi-2 - Thingiverse: https://www.thingiverse.com/thing:5967610

i cannot access any node via USB to flash. I've done everything the docs say (https://help.turingpi.com/hc/en-us/articles/8687165986205-Install-OS). None of the nodes can be reached via USB via host-mode. I've tried several USB cables. Where could the problem be? I have CM4

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

Looks like there is some problem with my tracking number. Or it's okay and it'll update soon?

Found one myself thought I'd start a forum to find others that work

Hola! I just got my Turing pi and I'm noticing that the SATA controller works on PI OS but not on Ubuntu. For example: Pi OS:

In dmesg I find

errors: I saw mentions that the SATA controller should work in Both OS's. Has anyone been able to get Ubuntu to work?

Greetings All ... I've come a long way. I connected to the BMC with the USB / TTL cable, set the static IP and enabled SSH root access. Now it's time to load an OS on the CM4s. Note that I've done this a dozen times using a Raspberry Pi connected to a CM4 plugged into an IO Board. So I've got the gist of it. But the process of doing this on a Turing Pi 2 is a little confusing, particularly when I try to follow the online instructions. First question is, do I need an SD card installed on the Turing Pi 2 board to do this? The instructions are a little nebulous. All four of my CM4s have eMMC flash memory. But the instructions refer to the SD card a few times. Next, I have rpiboot installed on a PC, and the PC connected to the Turing Pi 2 via the USB A to USB A cable. I get a "Device not recognized" error from Windows when I establish the connection. But I wasn't really expecting Windows to understand what the Turing Pi 2 board was. I run rpiboot, it goes into wait state. I plug in the USB cables and connect the PC and the Turing Pi 2, then run the specified tpi command, and nothing happens. I recall there being a USB enable feature on the CM4 that was corrected by using a jumper. But I'm not sure if there's a software setting equivalent. Thoughts? Thanks ! Sincerely ... Stephen

Hi everyone. Flashed the most recent BMC firmware, can SSH in now. For some reason using the USB to serial adapter (with the pins in the correct orientation, RXD, TXD, GND) I get garbled output on Putty. Settings are as recommended on the website, 11520 and for me COM3. I know it's connected since I see garbled output but am unable to get the BMC boot information in useable language. Have checked to ensure I have the right translation, but still not able to see proper characters. Has anyone had the same problem, and if so what were your putty settings to solve it? Thanks;

Starting a general thread for Jetson Nano support. I have a Jetson Nano without the developer kit that I plan to use with TPI2, but I'm running into problems getting the board working. I can plug the board into slot 1 and get the Android Boot Menu on a screen, but it's not possible to select the recovery mode needed to install the OS/Jetpack. Has anybody had success installing the OS using only the TPI2 board?

Hi, I have tried different power connectors to use with the pico psu but non of them are compatible. Which size or type is adapted to the pico psu ?

It seems to be the case that my raspberry pi compute modules make a high pitch noise when powered on. I’m starting to suspect this may have something to do with using the pico PSU. Is anybody else experiencing this? Has anybody been any to test their Turing board + compute module with a different power supply and see if it still makes noise? I don’t have things necessary to do this unfortunately. Curious about others experiences.

Yay for first draft 🎉. Going to chew on this for a while and see if I can't beautify it a bit. Not sure how much is changing with the next firmware but I can see some areas to simplify. Main one is removing the

opt

query param and use HTTP Methods. -

GET

returns the current state (get power|nodeinfo) -

PUT

updates the node state (set power, etc) -

POST

perform an operation, set bulk data, or upload data (network reset, firmware update) Second is make the routes more deterministic by moving the

type

query param into a path. Example:

bash
# BMC USB State
curl -X GET 127.0.0.1/api/bmc/usb
# Array response
curl -X GET 127.0.0.1/api/bmc/info
curl -X GET 127.0.0.1/api/bmc/power
# Single node response
curl -X GET 127.0.0.1/api/bmc/node/1/info

# Set Power using Array
curl -X POST -d '[1,1,0,0]'  127.0.0.1/api/bmc/power
# Individual control
curl -X PUT -d '1' 127.0.0.1/api/bmc/node/1/power

Hey I’m not able to flash my CM4s through usb as the device does not showing on my Mac. I have to use USB A-C as I don’t have any device to ich USB A anymore without using an adapter. Any ideas? Did all the steps from the docs but no luck. And as I only have one light model, my other two can’t be flashed with SD Cards as they just sit there without reading the SD card at all

Hi All ... I'm using a Thermaltake Tower 100 as the chassis for my Turing Pi 2. I'd like to set it up with illuminated fans to add to the Wow Effect. But all the RGB / LED enabled 120mm fans I've seen - including the ones I purchased recently - rely on a connection to the motherboard to enable the colorfulness. Ideally, I'd like something that runs off of either a Molex or SATA power cable, as the 450W Power Supply I cobbled into the Thermaltake chassis has more than enough of both plugs available. The current setup runs off of a central, SATA-powered hub. But the hub clearly wants a motherboard connection that doesn't exist on the Turing Pi 2. I don't need pulsing, shifting, voice-activated lighting. A solid blue or white would satisfy my (largely silly) requirements. Thoughts? Sincerely ... Stephen

Greetings All ... Thought I'd share the details of my Turing Pi 2 configuration. After bumbling around with the Windows rpiboot tool, and refusing to dive into the Mac OS option, I fell back on an old favorite - the Raspberry Pi 2 Model B. I've got the Raspberry Pi 2 Model B running the usbboot / rpiboot tool, which is easily implemented and completely reliable. I've got VNC running on the Raspberry Pi 2 Model B, along with SSH. I've got a USB-A to USB-A cable connecting the Raspberry Pi 2 Model B to the Turing Pi 2. I can VNC into the Raspberry Pi 2, access the Web Interface of the Turing Pi 2, power off a Node, switch it to Device Mode, power it back on, then run rpiboot on the Raspberry Pi 2, and the Node set to Device Mode reads as two disks on the Raspberry Pi 2. This is useful for: Using dd to load an image. Reversing file-based configuration issues you inadvertently screwed up. Other fine purposes yet to be discovered. It's a Remote-Access Dream. And now I don't have to walk from my home office to my lab (basement) to futz with the Device Mode settings. That is all. Sincerely ... Stephen

When I want to power up the nodes the red led of the first node briefly turns on and then dims down again. The cm4 won't boot. The BMC is working and I can ssh into it, but I don't seem to be able to power the nodes. What did I do wrong?

Hi All ... Is there a way to enable SSH on a Raspberry Pi after the OS image has been installed, but without a monitor? Is there a config file I can edit to enable SSH on a Raspberry Pi, where I can see and interact with the filesystem? I installed a new image on a CM4, and now I want to enable SSH. But I can't connect a monitor or keyboard to the CM4. Is this possible? Sincerely ... Stephen

Using the https://help.turingpi.com/hc/en-us/articles/8942913487901-OS-setup guide on flashing the CM4 with dietpi for kubernetes, I cant login via SSH at the end. Using

ssh 192.168.178.81 -v

which I configures and is also showing up in the network (host name is not showing correctly in frizbox) and I only getting

Permission denied (publickey,password)

I also tried to use the ssh keys and configured those in the pi imager but with no luck, they are there in the

user_data

file but login is not possible. Any ideas or suggestions?
