Hi all,
I'm a new member and is seeking some assistance.
I have an Eachine 250 Racer and have decided to move to Librepilot from OpenPilot.
I'm having an issue when using LP GCS to configure the CC3D FC.
I can flash the firmware (bu_cc3d.opfw) using the rescue method via USB, but GCS will not show the FC at all in the drop down list whenever I try to 'Upgrade' using the Vehicle Setup Wizard.
See attached screen shots. I appreciate any help.

Hi, welcome.

Try reinstalling windows driver ?

Thanks for your help. I tried but it did not work.
I followed the steps and Windows 10 detected the FC as 'Copter Control' and installed the driver. However LP GCS is still timing out when trying to upgrade.
Any other suggestions?

The led are blinking fast after you apply power ?

[rmsingh256]

I don't think so. Green LED is solid, Blue LED is blinking once per sec.

If fading in/out slowly you need to flash firmware.



- Disconnect board
- Hit Upgrade&Erase button
- Connect board
- Wait until the board remain connected (maybe 30seconds after flashing finished)

Wow, that worked. Still don't know what I was doing wrong. I thought I did that at least 10 times .
Thanks for you help.

The normal firmware (Connect board and next Upgrade&Erase button) update works only if a firmware is already running and board connected.

After a bootloader update the only way to update firwmare is hit Upgrade&Erase button before connecting board.

I see it now, good to know.
