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
•
A
board.txt
•
An application-specific subdirectory that contains the following board configuration files:
— Image files for the FPGA, that have
100765_0000_04_en
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.
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
