C++ Startup file

[AKlep.1]

I would like the interrupt handlers to be written in the C ++ style, that is, they are static classes, but there is practically no information on the Internet about where to get a C ++ startup file or how to make it yourself. Has anyone encountered such a problem?

I'm not convinced it's a problem.

The startup file is in assembly because it needs to load the data segments into memory and other low-level things. Don't think you're going to replicate that in C++. Not sure what you mean by "static class".

Cortex-M architecture is designed to allow to aesily write the startup code in C. Have a look to:

But C++ is more complicatd.

The interrupt handlers have to be C functions, or static member of a class (and where to get the class pointer?).

It is a big work to write all in C++.

It is probably more interesting to write a C to C++ wrapper for each ISR.
