I3 Flash Failed

Allen-Bradley · PowerFlex 750

What does 10337 mean?

An attempt to flash the FPGA configuration device on port 3 has failed. This indicates a problem with the firmware update process, potentially leaving the device in an inoperable state.

Common Causes

  • Corrupted firmware image file or incomplete download interrupting the flash process to Port 3.
  • Transient power supply interruption to the FPGA module (Port 3) or control board during the firmware update.
  • Internal hardware fault within the FPGA device or its associated memory on Port 3 preventing successful write operations.
  • Incompatibility between the selected firmware version and the specific hardware revision of the FPGA on Port 3.
  • Data communication error (e.g., CRC mismatch) during the flash programming process to Port 3.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Verify the integrity of the firmware image file using a checksum utility before attempting re-flash for Port 3.

  2. 2

    Ensure a stable 24VDC control power supply to the drive control board and any external flashing tool for Port 3 throughout the update procedure.

  3. 3

    Attempt to re-flash the FPGA on Port 3 using a known-good firmware file and the manufacturer's recommended programming utility.

  4. 4

    Check diagnostic LEDs on the FPGA module or control board (Port 3) for specific error codes or patterns during a flash attempt.

  5. 5

    If the flash continues to fail, consider replacing the FPGA module or the entire control board associated with Port 3.
