SLOW IO using BDM Console IO

[mredekopp]

Hi,

I know there were a couple threads about this a year or two back, but I'm experiencing VERY VERY SLOW console I/O with printf (a few chars per sec.) with the MCF 5211 and MCF52295.  I'm using Codewarrior 7.1 (build 2502).

Can you tell me where in the library and/or header files to re-enable buffered (by line) I/O rather than by character.  Any solutions at all.  This is kind of a make-it-or-break-it issue as I'm using it in the classroom and students need debug capabilities that are faster...

Thanks,

Mark

I remember that thread, and its information was placed into a FAQ for this kind of situation. FAQ-28993 describes how to set up console I/O via BDM, and how to buffer it by line rather than character to improve output performance. Type "FAQ-28993" into the Enter Keyword box at the upper right of this web page and the search system should take you to it. HTH.
