dear danny and slacker.

1. we use cyclon ii.

2. my in/out/err device is jtag uart.

now about what happen :

if i use in sys_lib options "small c library", printf is working, but it prints in console window just a point "." on every char or integer. if "small c library" option disabled, printf do not print nothing.

** may be it is depends to memory mapping of compiler, like stack (we had problems with the sdram before).

thanks a lot.

alex.
