Hi Olle, Thank you for your reply It is a Cortex M4 STM32F427 (2MB Flash and 256kB of RAM, we use IAR), I had a look to your footprint link, it seems that the footprint is TOTAL: complete libraries (+all codecs): .text=710160, .data=11280, .bss=639136 (Size minus empty application size: .text=450112, .data=3044, .data=27420) So I think It should be ok. So if I understand I must make the Lib (with correct configuration files) with GNU tools or Visual Studio and then include it in IAR ? best regards, Seb ----- Mail original ----- De: "Olle Frimanson" <olle.frimanson at keystream.se> ?: "pjsip list" <pjsip at lists.pjsip.org> Envoy?: Mercredi 26 F?vrier 2014 18:59:05 Objet: Re: [pjsip] Porting to ARM Architecture with FreeRTOS Hi, First of all is it ARM7 or STM32 (Cortex M3/M4) it I bit of a difference. Secondly I think you need to consider PJSIP's memory requirements have a look on http://www.pjsip.org/testing/0.5.6.5/footprint-arm-rtems.htm and compare that with what you have on you have available on your board. Thirdly it's also a matter on CPU power, some codec might not run on ARM 7/Cortex 3/4, I know ST have ported Speex to STM32. You can use any tool GNU /IAR or other but they all are cross compiles from PC and for some Linux.

I have several questions : 1) Is it possible porting pjsip in this kind of architecture ? 2) If I understood correctly, I need GNU tools to make the library ? (do I need a Linux computer to make it ?) Thanks for you replies Best regards Sebastien _______________________________________________ Visit our blog: http://blog.pjsip.org pjsip mailing list pjsip at lists.pjsip.org http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org _______________________________________________ Visit our blog: http://blog.pjsip.org pjsip mailing list pjsip at lists.pjsip.org http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org
