[ export PATH="/home/dawild/ti-processor-sdk-linux-am437x-evm-05.03.00.07/linux-devkit/sysroots/x86_64-arago-linux/usr/bin:$PATH" ]

Navigate to the U-Boot source directory in TODO fill in and initialize the build

[ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=build_dir -j6 mrproper ]

[ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=build_dir -j6 interceptor_proto_defconfig ]

Build the u-boot image and SPL MLO

[ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=build_dir -j6 MLO ]

[ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=build_dir -j6 u-boot.img ]

Install the MLO and u-boot image into the boot sector TODO check paths

[ sudo cp -v build_dir/arch/arm/boot/MLO /media/boot/ ]

[ sudo cp -v build_dir/arch/arm/boot/u-boot.img /media/boot/ ]
