MB directory Contains subdirectories for any board variants that might be present in the system.
The subdirectory names match the HBI codes for the specific board variants. The
files in this directory contain clock, register, and other settings for the board.
SOFTWARE
directory
Can contain user application files that the MCC can load into the QSPI, BRAM, or
DDR4 on the board. The memory that is loaded depends on the image that you
implement in the FPGA. The images.txt file defines the file that the MCC loads.

You can connect a workstation to the USB debug port to update the generic configuration file,
config.txt, on the configuration microSD card.
The following example shows a configuration file that you can load into the configuration microSD card.

3.5.3 Contents of the MB directory
The MPS3 board MB directory contains a configuration HBI subdirectory that matches the HBI code of
the board.
The HBI subdirectory contains:
• A file of the form mbb_vxxx.ebf. This file is an MCC BIOS image.
• A board.txt file that defines the MCC BIOS image.
• An application-specific subdirectory that contains the following board configuration files:
— Image files for the FPGA, that have .bit extensions, and for the MCC, that have .rbe extensions.
