Thanks Yann, for fixing my doubts. While building tool chain for CortexM3 with GCC 4.3.2, I am getting error. Kindly see if this can fix by some way. I understand that now mcpu is deprecated so I have not used in setting. When I use Architure level as "armv7m" and Tune for CPU as "cortex-m3" [ALL ] For real value is [ALL ] For cortex-m3 real value is cortexm3 [ALL ] Unknown arch used in --with-arch=armv7m [ERROR] make[1]: *** [configure-gcc] Error 1 [ALL ] make[1]: Leaving directory `/newhd/gccCortexM3/ct-ng-trunk-20081115/targets/arm-unknown-linux-uclib cgnueabi/build/build-cc-core-static' [ERROR] Build failed in step 'Installing static core C compiler' When I use Architure level as "armv7-m" and Tune for CPU as "cortex-m3" [ALL ] For cortex-m3 real value is cortexm3 [ALL ] For cortex-m3 real value is cortexm3 [ALL ] Unknown arch used in --with-arch=armv7-m [ERROR] make[1]: *** [configure-gcc] Error 1 [ALL ] make[1]: Leaving directory `/newhd/gccCortexM3/ct-ng-trunk-20081115/targets/arm-unknown-linux-uclib cgnueabi/build/build-cc-core-static' I also tried "armv7m" and "cortexm3" still it is giving error. I have seen gcc 4.3.2 manual also so according to them right way is "armv7-m" and cortex-m3" What extactly I have to use for Architure level and Tune for CPU ? Or I have to change some thing else here. Regards Vivek -- For unsubscribe information see http://sourceware.org/lists.html#faq
