NiosV and juart-terminal

I had a project which works fine under niosII. I upgrade all the project with niosv and all seems fine except printing values in juart-terminal. Here is the main code :  #include <stdio.h> #inclu...

Hi ETang2​ ,

The problem is when after this breakpoint i execute the code step by step the printf print the wrong values in juart-terminal.

Noted, sorry for misinterpreting your first post.
You are right that there is something fishy here.

  • Breakpoint before printf shows printed variables are memcpy correctly from intermediary value.
  • Execute the code step-by-step, and yet the printed variables shows 0.  

Please allow me some time to think this through.

 

On the 2nd issue:

It seems also that there is print problem as the accentuated character "é for example" are not printed correctly. 

I believe it is due to the default code page of your Windows Command Prompt. Nios V Command Shell follows the default code page.

Can you check your code page by typing this command in the niosv-shell?

If the results is 437, then this code page is unable to print é. The character é is stored as two bytes (0xC3 0xA9). Code Page 437 tries to read these as two separate characters (like ├⌐).

To change from Code Page 437 to UTF-8, 

In my previous comment, I was running my experiment in Linux.
And Linux terminal supports UTF-8 by default (unlike Windows Command Prompt).
