“Flashing” (Installing) Operating System Images
onto the Devkit
This documentation does not include OS-specific install instructions. Each operating system
image ships in its own distribution pack, and developers should consult the documentation for
that operating system image for details on how to install it. However, all of the OS support
packs require the devkit device to be in recovery mode as a first step. The operating system
image packs will in turn reference this documentation with regards to placing the device into
“recovery mode”. Recovery mode is a special, low-level booting mode that leaves the device
ready to receive a new operating system image over USB.
Placing the Devkit into Recovery Mode
To place the devkit into recovery mode:
1) Connect the 15V power supply to the devkit and to mains power.
2) Power on the device
a. If the device turns on immediately (i.e. the red and green power LEDs near the
center of the main board turn on), you may wish to ensure that the “ACOK”
switch on the front edge of the main board is in the leftmost (BATT) position for
future use.
