Hi, I've made a toolchain from buildroot-2010-11 with same options as toolchain available from friendlyArm. I've also compiled linux ( linux-2.6.32.2-mini2440-20100921.tar.gz ) with this new toolchain and using rootfs ( from rootfs_qtopia_qt4-20100816.tar.gz ), all seems ok. If anyone wants to try it, I've put my buildroot config at http://www.murlock.org/mini2440/buildroot-2010-11.config With friendlyARM $ /opt/FriendlyARM/toolschain/4.4.3/bin/arm-linux-gcc -v Using built-in specs.
