GetChar(), getc() and gets() NOT working on NIOS build on Cyclone 5

[ImranHK]

I have a custom board and am having trouble receiving data on stdin. All the stdout functions like printf() and puts() work just fine.

I have tried small, standard and uc/OS builds with same results.

The project builds fine and I can start the debugger fine. I was also wondering if there is a non blocking calls to stdin.

Thanks.

Thank you for the reply. I was able to debug the problem using SignalTap and it was not in the fpga side of things.

Did you use "Enable Small C library" for NIOS? If so its normal that they didn't work.
