Troubleshooting

• The OSD version of FC does not enter Bootloader mode

  • It is tricky to jump the exposed Boot pins. Try applying a bit of force when pressing on the pins. If possible, also try verifying they have actually been jumped with a multi-meter.

• On the Firmware Flasher tab, when clicking Flash Firmware button, the progress bar turns red and shows “No response from the bootloader, programming: FAILED”

  • This is likely due to the FC not being in Bootloader mode. Please double check the indicators of that mode in the section above.

• On the Firmware Flasher tab, when the flashing started and user verified “Flashing…” on the progress bar, eventually the flashing/verification failed with a “Timeout” error.

  • Click the Flash Firmware button and try again

• If the user experiences other issues or the steps above do not resolve the problem, please contact our hardware team via email.
