Beaglebone documentation updated

October 12, 2012

Hi all,

I’ve got some reports that my Beaglebone guide is outdated and giving some troubles regarding the bootloader and kernel.

While as of vanilla kernel 3.6.1 doesn’t support the beaglebone, U-Boot 2012.10-rc3 does support it, so i’ve tested all thechanges and updated the guide accordingly.

You can find it in http://dev.gentoo.org/~armin76/arm/beaglebone/install.xml
Some changes i’ve noticed in almost a year since i did the documentation:

  • The bug (by design they said) which made the USB port stop working after unplugging a device (check my post about the Beaglebone) is now fixed
  • CPU scaling is working, although the default governor is ‘userspace’. The default speed with this governor is:

a) 600MHz if powering it using a PSU through the 5V power connector, remember that the maximum speed of the  Beaglebone is 720MHz

b) 500MHz if powering it using the mini-USB port

Have fun
