Failed to Talk to Bootloader

Hi All,

I finally got a separate 12V battery and powered my OSD and fixed my 3DR telemetry cable setup, but when I try to talk to OSD I get a "Failed to talk to bootloader" I have solid red light on the OSD and my 3DR telemetry works fine.  If I try to load firmware or click the Read From OSD button I get the failed to talk to bootloader message.  Anyone know what might be my problem?

I'm using ArduCAM OSD Config 2.1.2.0 software.

Thanks,
Richard

  • My Pixhawk works as advertised with the  OSD.

    Is it possible to talk to the OSD through the Pixhawk? (It isn't easy getting my OSD out of the copter)

    I added the OSD's RX and TX signals from/to the Pixhawk. 

    Since Michael Osborn created both OSD and MP, is there a Mission-Planner setup for the OSD?

    The latest MP 1.3.10 has a OSD under Initial setup>Optional Hardware>OSD> "Only use this if you are having an issue of your OSD not updating"

    PS: Some relevant links ...

  • Leaving this here for posterity.

    At the suggestion of one of the guys on an RCG thread tracking this issue, I rigged up a 6 wire connector (in place of a 4 pin connector) to the MinimOSD which added I believe a RST signal to the mix.

    I no longer have to press the reset button nor am I getting the "Failed to talk to Bootloader" error message.

  • I have 2 of the v0.1 versions of this board.

    5v power pad is soldered

    NTSC mode

    Sparkfun FTDI breakout board

    Running MinimOSD-extra - pre-release candidate r462 along withe correct config tool.

    Both work just fine - but I do get the "Failed to talk to Bootloader" on the 2nd one.  I can read from the board and I can write to the board but it takes pressing the RESET button on the board just moments before you click "Save current tab to" from the config tool.

    Same deal with uploading firmware or charactersets.  You have like a 2 second window to press reset then select the file to upload.

    I power the boards from the 5v side, so only video and ground go into the pins on the right side.  I'm not sure what the firmware update did to upset the bootloader but it'll be interesting to investigate further.

    While I had my 850mAh 3S 11.1V battery plugged in testing, I noticed that the Lawmate 1.2 antenna was extremely hot.  I mean melt your finger hot.  Is this normal?
