Title: Firmware problems
Post by: RonnKruis on April 19, 2016, 06:12:40 pm

After trying to setup my board i seem to have done something wrong during the firmware upgrade process.
I added a screenshot of what the firmware page looks like if a press the rescue button.

What file do i need to restore the device back to normal?

Hi, welcome.

All files are already packaged with Gcs.

Go to firmware tab:
- Disconnect board
- Click Upgrade&Erase button
- Connect the board to automatically install firmware and erase flash.
- Wait the Erase process, take at least 30s

After the process completion, board should become connected to GCS.

Hi,

I know. I have often upgraded several Flightcontrollers with a GCs but they are not seen in the GCs so iam not able to do a normal Upgrade & Erase.
The only option to see the device is to start en rescue and that leaves me with the screen you see in the screenshot.

Ok i just found out that the boards have been flashed with Tau Labs. That seems to be the problem they don't work in Librepilot. How do i flash them back so that iam able to use them with librepilot.

The board i use are Revomini's from BangGood.

You need to solder directly a wire to the bootloader pin (pin 60) and set high, connected to +3.3V
After you add the wire you should not see led on.

Revo Mini is recognized as a Revolution.

You should flash using the 1 or 2
