nios2-terminal can't read input from pipe

Honored Contributor II

I get this error when I try to pipe even one line into nios2-terminal: 


nios2-terminal: error: Gathering input from STDIO 


I'm running 16.1 196 on Windows 7. 


I've tried using cat as well as my own C program that does a popen() around nios2-terminal. 


cat test.cmd | nios2-terminal -i 0 


If I type the input manually into nios2-terminal, it works fine. Unfortunately, I need to send many lines to the nios2 CPU. 


I've searched the forum posts and have found inconsistent information, including a mention that this could be a bug that has not been fixed yet. 


I do not currently have Quartus Pro so can't use the System Console TCL method. 


Any advice would be appreciated.  

Thanks in advance.

Our FAE confirmed this bug.  


The workaround I'm doing is to use the system console and a separate jtag master.
