Hi I have compiled the u-boot for at91sam9260 board, using the gcc compiler 4.3.2 , with the below config Target: arm-unknown-linux-gnu Configured with: /home/developer/crosstool-ng-1.3.1/targets/src/gcc-4.3.2/configure --build=i486-build_pc-linux-gnu --host=i486-build_pc-linux-gnu --target=arm-unknown-linux-gnu --prefix=/opt/x-tools/arm-unknown-linux-gnu --with-sysroot=/opt/x-tools/arm-unknown-linux-gnu/arm-unknown-linux-gnu/sys-root --enable-languages=c,c++,fortran,java --disable-multilib --with-float=soft --with-gmp=/opt/x-tools/arm-unknown-linux-gnu --with-mpfr=/opt/x-tools/arm-unknown-linux-gnu --with-pkgversion=crosstool-NG-1.3.1 --enable-__cxa_atexit --with-local-prefix=/opt/x-tools/arm-unknown-linux-gnu/arm-unknown-linux-gnu/sys-root --disable-nls --enable-threads=posix --enable-symvers=gnu --enable-c99 --enable-long-long --enable-target-optspace Thread model: posix gcc version 4.3.2 (crosstool-NG-1.3.1) . The board comes , with this u-boot , but most of the commands in the u-boot leads the board to a hang. the extra flags used for the compilation of the u-boot uisng 4.3.2 gcc are as below PLATFORM_CPPFLAGS += -mtune=arm926ej-s -march=armv5te when the u-boot is compiled with another gcc 3.4.4 config as below Configured with: /home/tsewell/crosstool-0.38/build/arm-linux/gcc-3.4.4-glibc-2.3.5/gcc-3.4.4/configure --target=arm-linux --host=i686-host_pc-linux-gnu --prefix=/opt/crosstool/gcc-3.4.4-glibc-2.3.5/arm-linux --with-float=soft --with-headers=/opt/crosstool/gcc-3.4.4-glibc-2.3.5/arm-linux/arm-linux/include --with-local-prefix=/opt/crosstool/gcc-3.4.4-glibc-2.3.5/arm-linux/arm-linux --disable-nls --enable-threads=posix --enable-symvers=gnu --enable-__cxa_atexit --enable-languages=c,c++ --enable-shared --enable-c99 --enable-long-long Thread model: posix gcc version 3.4.4 every thing works in u-boot. the extra flags used for the compilation of the u-boot using 3.4.4 gcc are PLATFORM_CPPFLAGS += -mapcs-32 -march=armv5te -mtune=arm926ejs IS There some extra flags need to be given for the 4.3.2 compiler to make the code.
