ArduIMU V3 - Problem during upload - Discussions

Hi every,

I'm a newbee and sorry in advance for this question.

When I try to upload the program into the ArduIMU V3, I obtain the following things :

Yellow led binks 2 time
Blue and Red blink together 1 time

In the Arduino software, there no ending message until I disconnect the USB cable from the Arduino IMU V3 and get the message "avrdude: stk500_getsync(): not in sync: resp=0xbc"

I set the Board as "Arduino Duemilanove w/ATmega 328"

If I use the Serial Monitor to check the connection, I obtain a lot of unreadable character problably those send by the IMU with the default loaded software.

EDIT : Now I get readable character by setting 115200 baud

Thanks in advance for your help, Marco.

EDIT : The FTDI cable is the DIYDrones FTDI Cable - TTL-232R-3V3 http://store.diydrones.com/FTDI_Cable_3_3V_p/ttl-232r-3v3.htm

EDIT : I'm under Windows 7

EDIT : Verbose output gives :

Version 5.11, compiled on Sep 2 2011 at 19:38:36

HI Marco, I am having a similar same problem. I can read off the values from COM port, but I cannot upload the code. If you solved the problem, can you advise me how you did it, please?

Was the 3.3V cable was the problem? Thank you very much in advance.

I just received an ArduIMU v3 and I have the exact same problem. I think my problem is that I don't have a proper FTDI cable and instead use a Bus Pirate which doesn't have the DTR signal available. I thought all this meant was that I had to manually reset before uploading, but that doesn't seem to work. I have an FTDI cable on order from SparkFun, so I'll post an update with whether or not that solved the problem.
