Thank you. Good info.

Hi,

I think I need to burn the bootloader onto my new ArduPilot board.

I have the FTDI breakout board but it sounds like I need an AVR programmer.
I found an AVR programmer in the UK, but i'm not sure if it is compatible..

The plug on the other end from the usb looks like it wont fit anything on the ArduPilot board. So my question is, do I need another adaptor of some kind, or is the above Url completely the wrong thing for what I need to do?

Excellent network here, looking forward to cutting some code for this board.

Thanks,
Paul

Paul, why do you think you need to burn a bootloader on the board? It came with that preloaded.

But if you have toasted the bootloader somehow, yes, you need an AVR programmer. I've never seen that one you linked to and it does indeed have the wrong connector (it should have a 3x2 connector). I suggest you buy a real AVRISPII

From my PC, I get an error from Arduino when attempting to upload the ArduPilot code to the board:
protocol error, expect=0x14, resp=0x51

From the bits and bobs I have read, I figured the bootloader could be the culprit, but i'm pretty new to this, so I am open to suggestions :)

Have you been through ALL of these debugging tips?

Thanks Chris. Yes I have been through the debugging tips.

Can you think of any reason why the bootloader would have been toasted? It's usually pretty robust.

None at all. My soldering isn't great, but it's not that bad.

When I power up the board, the yellow and blue lights flash... yellow then blue. This sequence increases in frequency (I think they flash about 6 times in all) and then repeats.

One other thing: The red power light always comes on when I power up, but the battery light only comes on now and then (when I unplug and re-plug the power supply)

I'm using a BEC as the power source, set to 5V.

Paul. That LED flashing behavior is just a LED test routine that Sparkfun runs at the factory. It means that everything's working right.

What the "battery light"? ArduPilot doesn't have one. Please identify it using this post as a reference.

Sorry my bad. It is the MUX light (not Battery!)
