5.1 Powering Up the Fusion Application Board

The Fusion board requires configuration before use. Perform the following configuration steps to avoid damage to the system components. The following configuration is for an eight-camera, surround-view system using the Fusion board and TDA2Px EVM. Power to the Fusion board is supplied by the TDA2Px EVM.

  1. Ensure the board is not connected to any power source.
  2. Ensure that the Fusion board has the appropriate hardware to mount onto the TDA2Px EVM to keep a sturdy connection. The CSI-2 connector from the TDA2Px EVM connects to the bottom side of the Fusion board to the CSI-2 connector.
  3. Connect the Fusion board to the EVM.
  4. Locate S3 on the board (see Figure 3). Table 9 lists the switch sequence for this startup application.

    Switch Switch Status
    1 On
    2 On
    3 Optional, dependent on sensors
    4 N/A
  5. Locate S4 on the board (see Figure 3). This dip switch controls the deserializer mode for the four coax connectors (J23 to J26). Because these connectors are coax only, there is only one configuration the switches can be in.

  6. Locate S5 on the board (see Figure 3). The dip switch controls the deserializer mode for the eight Radar/Coax connectors (J28 to J35). Ensure the decision to use all HSD or all coax for this bank has been made first, beacause there are two distinct modes depending on the connector. Table 11 lists the two modes and the positions of the switches.

  7. Set the jumper on J27 for the specified voltage of the sensors. For the configuration, see Figure 5.
  8. Set the jumper on J22 for the specified voltage of the sensors. For the configuration, see Figure 6.
  9. Connect the sensors with the chosen connectors.
  10. Provide power to the board. The Fusion board can be powered from the TDA2Px EVM (J40). After powering the board, the status LEDs should illuminate, indicating operation, see Table 8 for indications.

After programming and setting the hardware correctly, the TDA2Px EVM starts to receive the data streams from the CSI-2 output ports if the Fusion board is connected.
