Has anyone managed to get posenet working on a RASPI4, using the Google Coral USB accelerator? If so, would you mind to share your github repo.
I'm looking to run this demo on a raspi.
[https://storage.googleapis.com/tfjs-models/demos/posenet/camera.html][1]
I keep running into mixed issues, from segmentation fault to just random errors. Reading through all the blogs it seems it might be a performance issue of the USB slot?
Any thoughts are appreciated.

I got my hands on an already deployed yocto system (yocto 2.6.2 - thud) on a board with a NXP i.MX 6UL Cortex-A7. My only possible access at the moment is via wifi. I have access as root via wifi with ssh. The board is embedded into a case which I can't open. So no physical access to that board - just wifi.
My further intention is to setup/deploy/flash my own OS (yocto/debian/etc.) onto this board, but I have no proper knowledge to do so...
Is it even possible to flash a new image only with wifi access?
Which step is the next one I should consider?
Are there any documentations to start with?
Thanks
From your comments, I mention that you have the Variscite DART-6UL module. The producer of your module provides a wiki with lots of information and tutorials on how to start work with. Variscite DART-6UL Wiki
How to build your yocto system
Ready solution for update - SWUpdate Guide
Using SWUpdate is the easiest way to achieve updates for your module.
Custom solution:
Another way is to develop your own mechanism. In this case, you can do developed all processes and make them fully automatic, but it is complicated and required knowledge and experience.
For development boot from the server
For the development time, it can be useful to use booting from TFTP/NFS server. More information here

Right now I am programming an i2C script to read some pH data from a sensor at work whatsoever. I need to clone something from GitHub but it always says that the server certificate verification failed. When I wanna visit GitHub.com via Chromium it says it has an insecure connection to this site. I can ping the page but neither open it in the browser nor clone something from there. I am using a Raspberry Pi 3B with the newest Raspbian version with a working internet connection via Ethernet (or WiFi, neither creates a problem with any website). My workplace gave me a Certificate to install, if I want to use something else then Microsoft Edge. My thought was, that it is needed on the Raspberry Pi too, but I´m just not able to install it. I´m new to Raspbian programming and I have tried my best to understand the internet forums but I´m at the end of my knowledge. Does somebody know what to do? Or what to change?
Thanks for every answer

I've started learning Software Defined Network and therefore I need a testing environment to understand as well.
Like other network testing environment, I realized that I need a simulator or emulator like GNS3. Recently, I've found OpenFlow vSwitch but couldn't get enough.
The question is, how can I run an SDN testing environment on Linux, Raspberry Pi, etc?
Any information would be appreciated.
If you want to setup a SDN environment for learning purpose then best tool is mininet. It is very easy to install and setup.you can also find lot of tutorials online.
You can refer this link for its installation and basic understanding : https://konquerouter.wordpress.com/2017/11/24/learning-sdn-software-defined-networking-concept-with-mininet/
i am having a small problem which is quite critical actually, i run a Unity instance in a google cloud VM that work as a server for a small social experience in VR.
The thing is, if Unity is running without GPU, it starts clogging the processor and the game kindda fails with many users, that is why i hired a eGPU Tesla P4, also, to run Unity, i must log in with Remote Desktop and hit Play.
The thing is, Windows disables the GPU when you go Remote Desktop, Unity opens without a GPU and the GPU is "Unknown" (in dxdiag), thats why i need to solve the RDP issue, i need to log in without disabling GPU acceleration so unity can open and go full power running my game, the server is like a player that doesnt show for the other clients, since its made in Photon PUN, its a weird hybrid, but it works as expected.
Now i have to solve this performance issue, i hope i am clear.
what i need to do now: log in with hardware acceleration (paying a lot for that online gpu and not using it).
What i have now : i log in without using the GPU, the CPU dies, and im wasting cash on the server.
thanks community!
PS: in a future i will use a headless server.
It seems this is a 'Windows' feature that many people have been complaining about. Basically windows switches to a generic driver when you are connecting via remote desktop. Try using an alternative remote desktop solution such as VNC.

I am interfacing with some external hardware (can't disclose much details on hardware) and I am using Ethernet cable to talk to external hardware boards. I have windows 7 on my machine. In between the external hardware and my PC, I have a small ethernet hub that communicates with multiple circuit boards of my external hardware.
Also, in order to get internet connection on my PC, I am using a USB2Ethernet adapter which provides me the internet connectivity.
The problem I am having is that whenever PC is connected to internet, certain test that I run on the external hardware do not work. If I dicsonnect the internet cable, then my external hardware works fine and I can do my testing.
I have disabled the USB2Ethernet through device manager and (I get no internet) and tried to run the test and my hardware doesnt work.
Has anyone encounter a problem like this and if so, what would be an ideal solution? Any help would be greately appreciated.
Please feel free to contact for any other information related to the problem if I haven't explained it well.
