[Sdcc-user] printf and garbled output

[Mark S. <mar...@ch...>]

I am having a serious problem with printf intermittantly outputting 
garbage when I call it.  I have tried printf_fast and gotten the same 
results.  Has anyone else had this sort of problem with printf?

I am using  SDCC 2.4.0 for windows compiled with MinGW.  My target 
system is a Cygnal C8051F330.

My first thought was that my serial transmit buffer was overflowing or 
getting corrupted somehow.  However, I am unable to duplicate any issues 
when I send a bunch of characters using putchar directly.

Does anyone have any thoughts?  I can post some code if that will help.

Thanks,

Mark Swayne
