config.txt

file

Generic configuration file for all motherboards. This file applies to all Arm development boards
including the N1 board.

LICENSES

directory

Contains one license text file.

directory

Contains one or more HBI subdirectories for board variants. The subdirectory names match the
HBI codes for the board variants.

HBI0316?

subdirectories

Contain pointer files that define BIOS images for the MCC, the

Power Management IC

(PMIC),

and the IOFPGA, SCP, and MCP. Other files contain image, and configuration information for
the board and IOFPGA.

SOFTWARE

directory

Contains application files for the SCP and MCP. The

images.txt

file defines the image files.

3.3.2

config.txt

board configuration file

You can connect a workstation to the DBG USB port to update the generic Arm development board
configuration file

config.txt

in the root directory of the microsSD card.

The following example shows a typical

config.txt

configuration file in the root directory of the

configuration microSD card.
