I'll try to simplify the<br /> steps I followed as much as possible.</p> <p>I have the Sourcery Unix toolchain available on LeafLabs website<br /> (gcc-arm-none-eabi-latest-linux32.tar.gz) as a base for the new<br /> toolchain. In Linux, I can compile and upload a binary for a Maple Mini<br /> without problems (without the IDE).</p> <p>From Linux, I extracted the configure args of the Unix<br /> toolchain with:</p> <blockquote><p>$ arm-none-eabi-gcc -v<br /> Using built-in specs.<br /> Target: arm-none-eabi<br /> Configured with: /scratch/julian/2010q1-release-eabi-lite/src/gcc-4.4-2010q1/configure --build=i686-pc-linux-gnu --host=i686-pc-linux-gnu --target=arm-none-eabi --enable-threads --disable-libmudflap --disable-libssp --disable-libstdcxx-pch --enable-extra-sgxxlite-multilibs --with-gnu-as --with-gnu-ld --with-specs='%{O2:%{!fno-remove-local-statics: -fremove-local-statics}} %{O*:%{O|O0|O1|O2|Os:;:%{!fno-remove-local-statics: -fremove-local-statics}}}' --enable-languages=c,c++ --disable-shared --disable-lto --with-newlib --with-pkgversion='Sourcery G++ Lite 2010q1-188' --with-bugurl=https://support.codesourcery.com/GNUToolchain/ --disable-nls --prefix=/opt/codesourcery --with-headers=yes --with-sysroot=/opt/codesourcery/arm-none-eabi --with-build-sysroot=/scratch/julian/2010q1-release-eabi-lite/install/arm-none-eabi --with-gmp=/scratch/julian/2010q1-release-eabi-lite/obj/host-libs-2010q1-188-arm-none-eabi-i686-pc-linux-gnu/usr --with-mpfr=/scratch/julian/2010q1-release-eabi-lite/obj/host-libs-2010q1-188-arm-none-eabi-i686-pc-linux-gnu/usr --with-ppl=/scratch/julian/2010q1-release-eabi-lite/obj/host-libs-2010q1-188-arm-none-eabi-i686-pc-linux-gnu/usr --with-host-libstdcxx='-static-libgcc -Wl,-Bstatic,-lstdc++,-Bdynamic -lm' --with-cloog=/scratch/julian/2010q1-release-eabi-lite/obj/host-libs-2010q1-188-arm-none-eabi-i686-pc-linux-gnu/usr --disable-libgomp --enable-poison-system-directories --with-build-time-tools=/scratch/julian/2010q1-release-eabi-lite/install/arm-none-eabi/bin --with-build-time-tools=/scratch/julian/2010q1-release-eabi-lite/install/arm-none-eabi/bin<br /> Thread model: single<br /> gcc version 4.4.1 (Sourcery G++ Lite 2010q1-188) </p></blockquote> <p>So I sorted this all to create a cross compiler toolchain based on the<br /> toolchain above in OpenBSD. After compiling binutils, gcc, newlib and<br /> libstdc++-v3, I succeeded compiling libmaple + a simple Blink. Then<br /> downloaded maple_mini.bin into the board with dfu-util 0.8.</p> <p>The problem: after downloading the .bin and resetting the board, the<br /> program won't run after the bootloader stops. I've tried all sorts of<br /> configure args possible for gcc, but somehow gcc isn't generating code<br /> compatible with Cortex-M3/Maple or is something else I'm missing.</p> <p>Question: are there something obvious am I missing? Maybe some starting<br /> point or something like alike.</p> <p>Also had to modify support/make/target-config.mk</p> <blockquote><p>-TARGET_FLAGS += -mcpu=cortex-m3 -march=armv7-m<br /> +TARGET_FLAGS += -mcpu=cortex-m3 </p></blockquote> <p>since this leads to:</p> <blockquote><p>error: switch -mcpu=cortex-m3 conflicts with -march= switch </p></blockquote> <p>Any help is appreciated.<br /> Thank you. </p>
