git checkout v2017.11

2. configure it:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x_boneblack_defconfig

3. build it:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

  1. than copy MLO and u-boot.img to mmc:

cp MLO u-boot.img /media/inisider/boot/

  1. insert microsd to beagleboneblack slot than press ButtonSwitch (S2) and poweron BBB:
