ArduIMU Weirdness.

Posted by Teejay on June 19, 2010 at 10:08am
Hi,

Currently working on the IMU bit the ArduPilot...

Today, I decided to upgrade the stock firmware of my ArduIMU V2 (Flat) board to 1.7. Looks to be that the code compiled well, then I was met with the following message...

Binary sketch size: 16824 bytes (of a 30720 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x00"

Then I was just getting a solid green LED light and that's it. The IMU test tool won't work as usual.

Kinda stumped on what could have happened... any ideas?

And the ArduIMU is out of stock at the Store...

Thanks in advance.

Regards,
Teejay

    That error message is a general purpose communications error. Has this board ever worked before? Double check your soldering under a mag ect. I have gotten that message for no apparent reason and then it works on a retry.

    Try turning off everything, re-connecting, re-fiting the FTDI

    As this is saying that Arduino18 cannot see the 328 on IMU, no sync pulse...

    Normally, far short of IMU disctruction or broken FTDI, its normally a re-set and re-start thing...

    It happens every now and again with the normal AP also if the port is not set or it just got confused..

    so try that and see what happens........as long as you havtn shorted or blown up your IMU board this normally sorts it.

    Mike.
