Getting Started

  1. Download a fresh image: http://beagleboard.org/latest-images (Angstrom Linux)
  2. Flash an SD Card with that image.
  3. Keep the SD Card in your PC and open the uEnv.txt found in the first partition of the SD Card.
  4. Change the Argument from:
    optargs=quiet
    to
    optargs=quiet drm.debug=7 capemgr.disable_partno=BB-BONELT-HDMI
  5. Save the uEnv.txt
  6. Safely remove the SD Card from your PC
  7. Insert the SD Card into your Beaglebone
  8. Mount the MikroBus Cape
  9. Boot the board
  10. Log in via SSH or Debug
BeagleBone (White)

To allow BB to identify appropriate pin headers configuration, Click Cape have an onboard EEPROM programmed to make the use of the Cape “plug and play”, just insert the Cape and reboot the BB.

BeagleBone Black

From adoption of Linux kernel 3.x a new method to configure pin headers was introduced, at the boot time an in-kernel utility named “capemgr” dynamically load Device Tree definitions to configure an appropriate pin headers and bus initialization.

As in the case of the White, reading the information stored in the onboard EEPROM, the use of Click Cape is “plug and play” but needs that the user (just one time) put the *.dtbo file (downloadable from here) in /lib/firmware and reboot the system.

$ wget http://download.tigal.com/tigal/BBBmikroBUScape/BB_board_dtbo.tar  
$ mkdir bbclickdtbo
$ tar -C /home/root/bbclickdtbo/ -xvf BB_board_dtbo.tar
$ cd bbclickdtbo/
$ cp BB-MIKROBUS-01-00A1.dts /lib/firmware/
$ cp BB-MIKROBUS-01-00A1.dtbo /lib/firmware/
$ reboot
