Docker container and runner to cross-compile code for BeagleBone devices.
beaglebone-cross-compile will download the cross-compiler SDKs and install them inside a container.
No need to install CCStudio or build everything on-device!
Your host POSIX machine will need:
- bash (tested with 5.1.8)
- curl (tested with 7.79.0)
- docker (tested with 20.10.8)
- git (tested with 2.33.0)
- make (tested with GNU Make 4.3)

beaglebone-cross-compile --sdk gcc-arm -- makeClone the kernel source, check out the desired version, and cross-compile the kernel:
git clone https://github.com/beagleboard/linux
cd linux
git checkout -b ${TARGET_LINUX_KERNEL_VERSION}
beaglebone-cross-compile --sdk gcc-arm -- make bb.org_defconfig
beaglebone-cross-compile --sdk gcc-arm -- make LOADADDR=0x80000000 uImage dtbs
beaglebone-cross-compile --sdk gcc-arm -- make modulesIn your kernel driver project, set the BEAGLEBONE_KERNEL_DIR environment variable to the
cloned repository with the built kernel modules, and use --kdir in the options:
BEAGLEBONE_KERNEL_DIR="$HOME/Projects/linux" beaglebone-cross-compile --sdk gcc-arm --kdir -- makeThe GCC PRU SDK is for building firmware for the programmable real-time unit using the open source GNU GCC 10+ PRU cross-compiler.
beaglebone-cross-compile --sdk gcc-pru -- makeThe TI PRU SDK is for building firmware for the programmable real-time unit using the Texas Instruments PRU Code Generation Tools cross-compiler.
