6. The system loads the board configuration file:
• The MCC reads the generic config.txt file.
• The MCC searches the microSD card MB directory for the HBI0263x subdirectory that matches
the board HBI code from the board EEPROM.
7. The next steps depend on the configuration files:
• If the MCC finds configuration subdirectories that match the HBI code of the board, configuration
continues and the MCC reads the board.txt file.
• If the MCC does not find the correct configuration files, it records the failure to a log file on the
microSD card. Configuration stops and the system re-enters standby state.
8. The MCC measures the board power supplies.
9. The MCC configures the board clocks and FPGA SCC registers.
10. If the MCC finds new software images, it loads them into the SRAM through the FPGA.
11. The MCC releases the system resets nPOR and nRST, the system enters run state.
12. Normal operation continues until a new event occurs:
