3.6.2 config.txt generic board configuration file
You can use the MPS2 or MPS2+ FPGA Prototyping Board USB 2.0 Full Speed port to update the
generic configuration file config.txt from your workstation to the root directory of the microSD card.
The following example shows a configuration file that you can load into the configuration flash memory.
Note
• Colons (:) indicate the end of commands and must be separated by a space character (0x20) from the
value fields.
• Semicolons (;) indicate comments.

3.6.3 Contents of the MB directory
The MPS2 and MPS2+ board MB directories contain 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 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 and MCC on the board. These have .rbf extensions.
— An images.txt file that defines the .axf files that the MCC loads into external memory during
configuration.
— An application note .txt file that defines the number of FPGAs on the board, the number of
oscillators and their frequencies, FPGA and MCC image files, and details of the SCC registers.
The following example shows a typical MPS2 or MPS2+ FPGA Prototyping Board configuration
board.txt file.
