Why I can not see the alt_printf("xyz") output?

I implemented following simple code on Max10 dev-board:

--- Quote Start ---

# include <sys/alt_stdio.h># include "system.h"

int main()

{

alt_printf("test...");

}

--- Quote End ---

For some reason I can not see any output in the Console of the Nios-Eclipse environment. Maybe I need to re-direct the stdout in the nios-settings? If so where can I do that?

thanks!

    Yeah, that definitely is weird. If you want to change where stdout is redirected, you can do that in the BSP Editor (Right click your BSP Project->Nios II->BSP Editor). The stdin, stdout, and stderr redirection options should be on the root node of the tree that pops up. By default, it should be connected to the UART/JTAG UART that you instantiated inside of Qsys. Another thing to try would be to include <stdio.h> and use the regular printf. I know the alt_printf is a dumbed-down version of the regular printf, so maybe the regular printf will work.
