Mass-Production and Identification Checklist

  1. Verify the full controller marking, suffix, PCB revision, and interface.
  2. Read the Flash ID from every channel and CE, then cross-check the compatibility table.
  3. Select a tool version containing the matching Flash database and firmware branch.
  4. Mass production destroys data; do not write firmware or run production when recovery is required.
