.NET Core runtime environment on Raspberry Pi throws segmentation fault

I have tried to install the .NET Core runtime environment following one of the answers from here: Is it possible to run .NET Core on Raspberry PI?

I have checked that I have all the needed packages installed but when I run "dotnet --info" I just get segmentation fault. Strace does not give good ideas on what might be missing: https://pastebin.com/rBUbiYkV

Segmentation fault

What should I try next?

Solution

Raspberry Pi 1 contains an ARMv6 processor.

.NET Core requires a processor that can execute the ARMv7 instruction set since that is what the JIT emits:

Note: Pi Zero is not supported because the .NET Core JIT depends on armv7 instructions not available on Pi Zero.

So this is just not going to work. Sorry. Try with a Raspberry Pi 2 or 3 instead.

(If you are crazy adventurous, you can try porting the JIT yourself. I wouldn't try this unless you are very very comfortable writing ARM assembly, C, C++, C# and understand compilers deeply)
