Booting the BeagleBone Black
For the BeagleBone Black, we need the microSD card prepared in Chapter 4, Configuring and Building the Kernel, plus a root filesystem built using the arm-cortex_a8-linux-gnueabihf toolchain. Copy uRamdisk you created earlier in this section to the boot partition on the microSD card, and then use it to boot the BeagleBone Black to point that you get a U-Boot prompt. Then enter these commands:
fatload mmc 0:1 0x80200000 zImagefatload mmc 0:1 0x80f00000 am335x-boneblack.dtbfatload mmc 0:1 0x81000000 uRamdisksetenv bootargs console=ttyO0,115200 rdinit=/bin/shbootz 0x80200000 0x81000000 0x80f00000
If all goes well, you will get a root shell with the prompt / # on the serial console.
