Cannot upload to the FC

[Beetlex1968]

Hi Folks !

I have 3 FC and 2 FTDI Adapters Cables......

ALL of the Controllers work when connecting to the PC via the Cables MultiWiiGUI AND MultiWii WIN GUI the show nice behaving ....reacting to TX inputs...attitude changes..... but.....

i CANNOT upload new Multiwii Sketches onto them..( also no EEPROM Clear )....it breaks up with a timeout.."avrdude: stk500v2_ReceiveMessage(): timeout"

im using Arduino 1.06 IDE

any Ideas ?

Did you select the correct board and chip in arduino?

[Goetz]

did you try another USB-Port? preferrable one you normally don't use. If this doesn't help, de- and reinstall driver for your ftdi... ....you might try to deinstall all other COM-Devices so that reconnection to the ftdi does faster as the last option I know...

I had the same issue, try holding the reset button on the FC and press upload on the PC. When you se the uploading in audrino relise the reset and It will upload just fine.

No change
Just to make sure:
Board: Arduino 2560 or Mega ADK
Programmer: AVRISP mkII

what means install Bootloader under the Tool Tab ?

Thx Beetlex

First of all, are your FCs actually Arduino 2560? Which one are they exactly?
Bootloader should never be needed unless you actually flashed and messed up using the ISP port instead of FTDI.

Hi !

The Boards are Atmel 2560s.....either :

or

The upload with the USB board works ( at least with the HK Boards......at the other boards the USB Port went off )

And all Boards work fine when connected via FTDI to the MultiWiiGUI....but there ( FTDI) no upload is possible.....

I have a similar problem but it works with a old Arduino 1.01 IDE.
Maybe you can try this.
