Honored Contributorhow to use printf in NIOS2 DE2
I am a newbie in the FPGA and NIOS world, i came across some labs and scripts available on line where they build a simple SOPC based NIOS 2 processor (with interval timer, JTAG, onchip mem) and then they used Eclipse to make a simple hello world program that would use printf("hello world"); that is suppose to print the message on the console of the eclipse IDE. i cant get it to work as i get an error saying the .elf executable file not found or the SDTOUT is not implemented on the hardware. I would really appreciate any help... thanks in advance.

Altera_ForumSome people also create their projects in a folder inside "My Documents" which will also create that kind of problems.

NIOS has got problems when there are spaces in the filepath. So like "Altera Project" won't work nicely, but "AlteraProject" or "Altera_Project". The newest NIOS-Version normally warns you if there are any spaces in the path, I think. Check in the NIOS BSP-Editor, if the STDOUT is set to the right module and check your design, too.

I really don't get what you mean. Can you please give more details about the path that you want me to move in the project?

Do you have a space in the path to your project? If yes, move it somewhere else.
