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.&nbsp; I don’t think VS2005 can generate real mode code.&nbsp; 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
