This is the first time I’m using FreeRTOS (and even an OS) on my µC. I would like to get/make a version working with GCC. I have tried to use IAR but my Jtag cable is not recognized and the additional source code I have to use with FreeRTOS is in C++ and IAR is not good with C and C++ in the same time. I was looking into other project with GCC (specialy the ARM7\_AT91FR40008\_GCC) and I have noticed that I haven’t the same files for my STR71x. Can anyone explain to me how to change the makefile in order to get it work? Will I have to change some of my existing files in order to adapt it to the OS? Thanks a lot for your answers, I hope I’m not the onlyone trying to use GCC with a STR71x. Romain ---

Just check the timer set up is compatible with you uC. ---

Any idea/help for me? (even better, a working makefile if it’s possible 😉 ) Thanks a lot, Romain ---

Also if you are using gcc I don’t know why you would have an portasm.s79 file (which is presumable an IAR file). ---

So now I have to figure how write my makefile … And this is a big work :S I have no idea to begin with ☹ And I should transform some files I guess, even to write somme new one … So much to do for such a litle thing ☹ ---
