Cannot connect Maxserial

Hi everyone,

I have just assembled a maxserial which is supposed to be an Arduino Diecimila with a serial port and when its powered using a 9v battery.It turns on and blinks 1 time and then 3 times really fast like its supposed to according to what I have seen.

But when I connect it to my pc via a serial cable I get an error when I try to upload code to it. I have tried changing through all of the boards but it make so difference. Also when the controller is connected I dont see an extra com device pop up. Does anyone have any advice?

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00

You won't see an extra com device - you'll use one that already exists, the serial port you are attached to.

It also must be powered externally; there is no power from the serial port.

I made power supply using a 9v battery making sure that the center is positive. Its pumping out about 7 volts right now. I also connected to com1 which is the only port that shows up. I still get the error though.

Has anyone see the error message that I put in the first post?

It's a fairly generic message indicating the IDE can't talk to the hardware.

Could anyone give common reasons why it cant talk to the freeduino? I connect it and then turn on the serial monitor and it starts return 1-38 and then starts over again and it only does it if the freedunio maxserial is pluged in. Is that good news at all?

I also wanted to add that I have tried every board on the list and I also tried holding down the reset button.

Just in case anyone else has this problem is because you need to solder the tp1 ground. I soldered the bridge and then the upload worked.

Hello,

I'm having the same problem with my Duemilanove...

"Binary sketch size: 1464 bytes (of a 30720 byte maximum)

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51"

I'm connecting via USB, the green led is on, so it's receiving power... just uploading the LCD sketch...
Could this be realted with the Bauld rate transfer for the port? mine is in 9600... should I change that?

Thanksssss

Eddie
