Yes, you are correct. Actually, I had done that as a test when the flash programming was not working.
I removed that (back to 4 byte alignment), and everything works properly.
So, only the 8 byte stack alignment is needed.

The above does not aligne .data to 8 byte, but .ramfunc
The . operator always sets the current location counter. And here you
are just "behind" the .data segment. Right?

I'll dig out my Ethernut5 and will test it as well.
