Overload printf function on C28 and DSP/BIOS

Hi,

 i'm working on C2812 TEXAS DSP.
I'd like to redefine a printf function to send strings to serial port
instead of RTDX way.

Have an idea ?

I'd tried to redefined putchar or putc function, but it seems more
complex.

thx.

Hello,

How about using sprintf() to do the format conversion and build a
string and then using your own putchar function to print the string?

Yes, but I was wondering something easier exists. Some up/compilers
maps their I/O (printf) to serial port automatically, or allow putchar
override.

But it seems it is not possible with C28 and CCS compilation.
So, must do it from scratch ! again !

neverless, thx Clay !
