start with PC then port to STR912

I would like to develop a program using FreeRTOS on a pc using VS2005, once all will work, I want to port the whole application to ARM9 STR912 ( with IAR or Keil compiler/IDE). What should I be careful about? (Is it possible that just one file should be changed in the project?) Thanks Johanan

The PC port uses real mode.  I don’t think VS2005 can generate real mode code.  You could do what you want using OpenWatcom in place of VS2005.

Thanks, I already got into compilation problems – I thought that I could compile the PC port in VS2005 using a C consule application. It doen’t work, and I am not familir with OpenWatcom, should I? Thanks
