Hi there,
I’ve got 2 mega pro 5V and one original arduino mega, but am not able to make the sparkfun products work. I’m using a 3,3V FTDI cable (which actually provides 5V for power), Arduino 1.0.4 IDE, selected board is Arduino Mega 2560 or Mega ADK. The same hardware and software are used with both Arduino and Sparkfun. Arduino is fine, but sparkfun always get this message:
avrdude: stk500v2_ReceiveMessage(): timeout …
avrdude: stk500v2_getsync(): timeout communicating with programmer
I precice that I don’t use the USB on arduino, TX0,RX0 directly with the FTDI 3,3V cable, as with the sparkfun hardware.
One of the sparkfun bord seems to have a bootloader, the yellow led blinks a couple of times after a reset, the other one doesn’t even light the led. The auto-reset seems to work, as I see the led blinking when uploading the sketch.
Have you any idea what could be wrong, bad bootloader,? bad config? And how I could make it work?
Thanks for your help!
