I recently purchased Arducopter V2 DIY quadcopter kit and have everything ready to go. When I went to load the latest firmware through Mission Planner it gives me this verification error:
Upload succeeded, but verify failed: exp 2C got 2D at 3373.
When I goto Terminal with CLI switch in either position it shows the following but no prompt and no commands work:
Init ArduCopter V2.0.49 Beta
Free RAM: 18221245
FW Version 111
----------------------------------------
I am able to load the Arducopter V2.0.49 Beta Hil without any problems or verification errors. I get a green light after, CLI works without problems, and simulation works with flight gear??
I have also uploaded many smaller examples using arduino software and ran them without any problems.
Did I get a bunk board? Anyone have any suggestions on how to troubleshoot this?
Thanks
Jason

It's good that you found the problem (or at least the most important part of it) and shared it with us !
Thx and I wish you many successfull flights !
Great news! User error comes through once again, never seems to fail.
You know it helps if you solder the magnetometer on correctly. I couldn't figure out why the HIL firmware would work so I thought about what was disabled, GPS and the magnetometer. Since my GPS was working with the IMU shield off, I figured I would recheck the magnetometer when I noticed I had soldered it upside down. Upon soldering it correctly, Arducopter 2.0.50 freshly downloaded from the GIT loads and works yay!
So the magnetometer was shorting out upon boot and freezing the CLI. Hopefully someone else will learn from my mistake. I still get verify errors upon loading the firmware but I think that is a separate issue with the bootloader.
Anyways this has got me involved with the community and for that I am grateful. Thanks for your help!

So I am really at a loss here on what to do to get this working. I have spent the last 3 days trying to get this to work trying everything I could think of. Is it a problem with the IMU and not the APM???
When I connect an FTDI cable to the APM I am able to access the CLI without issue. I have rechecked all my solder points for the headers and they look good.
Again, just doesn't make sense why the IMU works without any hitches with the HIL firmware loaded, the only firmware which seems to work with the IMU attached. I am going to go through and retry the smaller example tests with the IMU shield attached, but they all worked last time.
Any ideas welcome, I'm stumped.
Ok so I reloaded the latest bootloader for the 2560 and I am able to upload the latest arducopter sketch via Arduino software without any errors using a FTDI cable. When I connect through the FTDI cable I can get to the CLI and issue commands without problems.
When I put on the IMU shield and connect via usb, the CLI freezes as shown above and no green light. I still don't understand why the HIL code gives me a green light and works with the shield on and no problems at all.
I am also able to upload the code with the IMU shield on via USB without errors using the Arduino software or Mission Planner, but again same issue as above.
what version of mission planner are you using?
Did you try to load code with arduino program manually?
