Hi! I have a BeagleBone Black with Debian Wheezy and want to cross-compile the kernel (need some additional modules not in the default kernel).
So far, I succeeded compiling the kernel and running it on the BBB, but then I get no HDMI output. For building on my Debian Wheezy x86_64 I did: ----------------%<----------------%<----------------%<---------------- sudo echo "deb http://emdebian.org/~thibg/repo/ sid main" >> /etc/apt/sources.list sudo apt-get install emdebian-archive-keyring sudo dpkg --add-architecture armhf sudo apt-get update sudp apt-get install gcc-4.7-arm-linux-gnueabihf lzop libncurses5-dev cd /usr/bin sudo ln -s arm-linux-gnueabihf-cpp-4.7 arm-linux-gnueabihf-cpp sudo ln -s arm-linux-gnueabihf-gcc-4.7 arm-linux-gnueabihf-gcc sudo ln -s arm-linux-gnueabihf-gcc-ar-4.7 arm-linux-gnueabihf-gcc-ar sudo ln -s arm-linux-gnueabihf-gcc-nm-4.7 arm-linux-gnueabihf-gcc-nm sudo ln -s arm-linux-gnueabihf-gcc-ranlib-4.7 arm-linux-gnueabihf-gcc-ranlib sudo ln -s arm-linux-gnueabihf-gcov-4.7 arm-linux-gnueabihf-gcov git clone git://git.denx.de/u-boot.git cd u-boot/ git checkout v2014.07 -b tmp wget -c https://raw.githubusercontent.com/eewiki/u-boot-patches/master/v2014.07/0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch patch -p1 < 0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x_evm_config make -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- cd .. git clone git://github.com/beagleboard/kernel cd kernel git checkout 3.8 ./patch.sh cd kernel wget http://arago-project.org/git/projects/?p=am33x-cm3.git\;a=blob_plain\;f=bin/am335x-pm-firmware.bin\;hb=HEAD -O firmware/am335x-pm-firmware.bin cp ../configs/beaglebone .config make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig # change nothing for testing; save .config make -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- PATH="/path/to/u-boot/tools:$PATH" make -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage dtbs modules mkdir -p ../../deploy/{modules,firmware,dtbs} PATH="/path/to/u-boot/tools:$PATH" make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules_install INSTALL_MOD_PATH=../../deploy/modules PATH="/path/to/u-boot/tools:$PATH" make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- firmware_install INSTALL_FW_PATH=../../deploy/firmware find . -iname "*.dtb" -exec cp -v '{}' ../../deploy/dtbs cp ./arch/arm/boot/zImage ../../deploy/ cd ../../deploy # mount mmcblk0p1 "BOOT" sudo cp --recursive dtbs /media/BOOT sudo cp zImage /media/BOOT # mount mmcblkp5 "rootfs" sudo cp --recursive modules/lib/* /media/rootfs/lib sudo cp --recursive firmware/* /media/rootfs/lib/firmware # umount & eject mmcblk0 ----------------%<----------------%<----------------%<---------------- If I then boot it, I see the new kernel beeing loaded, but when the display is enabled, it fails.
