No , it wasn't a exactly memory problem, the only problem what that memory where I was trying to execute was writing protected. So I execute everything in RAM memory (0x40020000) but printf still not working.
If I try to change printf by puts the program hangs on execution without showing anything on screen but ## Starting application at 0x40020000 ...
It's strange because scipts, echos, and kernel init messages (when I have tryed to boot a kernel) displays on screen (via serial port, using Tera Term software to visualize it) without anyproblem. And if I print the environment variables stdout is serial.
Thanks for your help.

Sounds like serious memory problems to me...

That's to be expected when your memory isn't working right.
