What’s New

The June 9th update below allows the device to be successfully powered from the USB connector. The BeagleBone Black has a current limiter that by default is setup to only allow 1/2 amp of current while powered from USB. The June 9th images reconfigure the current regulator at boot to allow up to 1.3 amps to be sourced from the USB. However, it should be noted that the USB specification is 500 mA of current, so a PC may still limit the current below the full 1300 mA this change allows. Powering from a USB phone charger is the intent of this change. A big thanks to Jordi Guillaumes Pons for pointing this out.

Booting from the Internal eMMC

This image can be directly copied to the internal eMMC memory and booted (it can be copied to the internal eMMC while booted from the external microSD).

The new bootloader is setup to probe the external microSD slot at boot time. If a bootable microSD is detected it will be booted instead. The result is that it is no longer necessary to hold down the USER/BOOT button at power-on to boot from microSD this way — the presence of a bootable external microSD card alone will cause it to boot. A non-bootable microSD still causes it to boot from the internal eMMC so one can be used for additional storage while booted from eMMC.

Booting from SD

If you have not yet applied one of these images, you will need to hold down the USER/BOOT button while powering-on the device to boot the BeagleBone Black from the external SD slot.

Ubuntu Precise 12.04.2 LTS Hard Float Minimal Image

This image uses the Ubuntu 12.04.2 LTS core filesystem from Ubuntu with the minimal meta package applied. The kernel is a Robert Nelson armhf 3.8 kernel. The result is an easy-to-install Linux image that works with both the BeagleBone and the new BeagleBone Black boards. If you want to do this on your own, step-by-step instructions can be found here.
