Set the cross compiler:: + + # export CROSS_COMPILE=/path/to/toolchain/arm-linux-gnueabi- + +3. Select the output directory (optional):: + + # export KBUILD_OUTPUT=/path/to/output + + for example: use one output directory for each configuration:: + + # export KBUILD_OUTPUT=stm32f4 + # export KBUILD_OUTPUT=stm32f7 + # export KBUILD_OUTPUT=stm32h7 + + you can build outside of code directory:: + + # export KBUILD_OUTPUT=../build/stm32f4 + +4.
