Problem with Printf

[Altera_Forum]

I ve written a simple C-program running on Nios with output on JTAG-Uart Console. 

 Why if the surce code is   int m; m=9; printf("%d",m);  everthing works perfectly while if the source code is modified in:  int m; m=10; printf("%d",m);  it does not work anymore ???

moreover 

 please note that this strange behaviour occours using Nios II(e),  while using Nios II(s) everithing works well.

Hi, telle us more information 

 for your 1st problem, What did you get ? "9" on nios2-terminal instead of 10 ? if so, clean and rebuild your nios project. Maybe the new soft was not correctly downloaded, did you get errors ?  For your 2nd problem, When you chose Nios II/e (=economic version), do you regenerate the Qsys, recompile the design, redownload to FPGA, do you rebuild the BSP, do you recompile the soft ?  regards

Thank you for your answer 

 The code is exactly what I write ! If I ask "printf" to write a integer number (%d) with a single digit it works correctly, otherwise (just changing the 9 in 10) the program restart from the begin in a infinite loop.  Actually I've similar problem also using the multiplier (*) operator: sometimes it work but with few marginal  changing in the code, the execution restart from the beginning in an infinite loop.  However I noticed that this problem is limited to the usage of Nios II-e, while just changing the processor to Nios II-s and with no other modification both the "printf" and the "multiplier" works correctly.  > When you chose Nios II/e (=economic version), do you regenerate the Qsys, recompile the design, redownload to FPGA, do you rebuild the BSP, do you recompile the soft ?  Of course !

Could be stack overflow
