"Oh yes.. I also saw the same problem again when I flashed to Version 2.9. Since going back to the original flashed version that came with the board i have not seen this weird code under the CLI again.
The Board I have is a RC_Timer APM 2.72"

"Thanks for your reply Craig.  I have managed to get my APM working again. Upgrading the firmware is a bad idea. I totaly down graded back to 2.72. (Possibly the original firmware when i bought it) And bang.. it all worked.. BUT I still had a…"

"Bump:  Down grading to an older version... would this solve the problems I'm having? The APM board is a 2.72. me thinks."

"Okey.. The weekend has been not been great. Been on the computer for the past 20 hours trying to get this apm ready as how i first bought it months ago.
1. I have flashed it successfully. Me thinks. I used ArduCopter 3.1.   (Had probs with the…"

"I could be having some degree of success. Thankyou so much for you guys help.  I have only just lost my com port.  Now its not working. Weird.. I will let you guys know when It all works"

"Thanks Bill for this.  I'm trying to cram all this in my head as I read this dev codec stuff.  It's going to take months to work it out for me.  I have down graded to the ArduCopter 3.2 platform. Now I get a few other errors i dont know what to do…"

"Never mind Marty.  I think I have just missed a step.  Hope all goes well from here on.
Cheers"

"Bill,  I am currently trying to Verify the arducopter sketch to the board.
But the sketch is too big.
I've tried to DISABLE options under the APM_Config.h and also have tried another program tools called MHV AVR Tools.  Is there another way? I have…"

"Just cleared the EPROM.  Maybe I have made it worse.  It was succesful although.
Once i'm under CLI and connect, it just says port open. I cant type in anything. So I need to install a frame type.  I tried this, and when the part comes (Reading Hex)…"

"Thanks Marty.  I don't usually use Arduino sotware.. I do have it installed, Do I need to type anything after i click on clear EPROM menu? Because i have gone back into APM and it still comes up The code EPROM ?."

"Ok.. I should delete this request.  It certainly does fly. I must have been over tired building this.
Thankyou so much for your help guys.

Cheers"

"I feel like such a doofus. I know I have the rotations the wrong way around. I am going to test this again.  How embarrassing."

"Hello,  Thanks for getting back to me.  I have updated the post with a better pick.  I have followed the steps again for the 4 time.  It is correct.. The blades are correct, the motors connections are correct. and also the rotations are correct. I…"
