Iot: Does .NET Core support Raspberry Pi 4?

[Penergy]

I have seen the instructions for .Net Core on RPi 2 and RPi 3 from this link.
https://github.com/dotnet/core/blob/master/samples/RaspberryPiInstructions.md

I want to know whether .Net Core has the plan to support RPi 4. Because we are going to use RPi 4 later.

@joperezr can answer that

hello @Penergy, thanks for logging the issue. Yes, .NET Core does run on Raspberry Pi 4.

In case your project involves controlling sensors or devices attached to the Raspberry Pi 4 using the GPIO header pins, head down to our new https://github.com/dotnet/iot repo where we are developing a .NET Standard 2.0 library that will support communication protocols (GPIO, SPI, I2C, PWM) with those pins in order to control other devices like motion and temperature sensors or motors.

The question was answered 14 days ago so I'm closing it as resolved. @Penergy feel free to ping us to reopen it if you have additional questions.

@joperezr I tried to install .net Core on my Raspberry Pi 4 unsuccessfully. Can you shed some light how can we do it? Thanks in advance.

Hello @Carlos-Carreno-Berlanga have you tried these instructions: https://github.com/dotnet/core/blob/rpi/samples/RaspberryPiInstructions.md

I usually follow those and it works, but another way you could also do it is by running the following in a terminal window:

wget https://download.visualstudio.microsoft.com/download/pr/3cb1d917-19cc-4399-9a53-03bb5de223f6/be3e011601610d9fe0a4f6b1962378ea/dotnet-sdk-2.2.401-linux-arm.tar.gz
mkdir -p $HOME/dotnet && tar zxf dotnet-sdk-2.2.401-linux-arm.tar.gz -C $HOME/dotnet
export DOTNET_ROOT=$HOME/dotnet
export PATH=$PATH:$HOME/dotnet

@joperezr The first link did'nt work. When I tried to execute dotnet command, I got "Exec format error".
The second set of instructions worked like a charm. Thanks a lot, I really appreciate that!!

[joperezr]

Nice! do note that the second instructions I sent only work on during the lifetime of the terminal window, since you would be exporting to variables (DOTNET_ROOT and PATH) only in your current window. If you want to instead make this a permanent change so that they are available in all of your windows you can follow these instructions:

You can edit your shell profile to permanently add the commands. There are a number of different shells available for Linux and each has a different profile. For example:

Bash Shell: ~/.bash_profile, ~/.bashrc
Korn Shell: ~/.kshrc or .profile
Z Shell: ~/.zshrc or .zprofile
Edit the appropriate source file for you shell and add :$HOME/dotnet to the end of the existing PATH statement. If no PATH statement is included, add a new line with export PATH=$PATH:$HOME/dotnet.

Also add export DOTNET_ROOT=$HOME/dotnet to the end of the file.

@joperezr Thanks again for that.

it's really a pity that they're not going to support windows iot for pi4

Hey guys. Any chance that pi4 would support sending the command to the USB connected printer from NET Core? I am interesting about Zebra printers and ZPL commands in particular

@vlyakh Referencing https://github.com/dotnet/wpf/issues/871

[krwq]

@vlyakh this is the first request we have about printers. I'd recommend exploring if there is already any .NET library anywhere which already supports it, perhaps: https://github.com/germanger/zpl-printer or https://github.com/rkone/sharpzebra will do exactly what you need.

If that doesn't work for you please create a feature request on https://github.com/dotnet/iot - note that we are greatly relying on community help with features so this might not get any traction for some time.
