Dear efind0813,
Dear Sirs,
In one of the 2 boards I bought , I am not able to upload software. The IDE claims it can not sync properly with the board. Communications apparently start, lights blink a few times and then it gets stuck until IDE aborts uploading,
The other one boards works fine, Same Computer , same cable etc.
Please your suggestions.
Thank you

hi frasenci :
1.i want to know what is your PC's OS
2.does the PC find the com of the board that not works well

Re: Iduino Mega 2560 Connects but no Sync
Hi Sean
I am connecting this boards either to Win XP 32 bit or Win 7 64 bits OS.
I have done it many times, in fact I am in the business ( a tiny one ) of integrating 3D printers in Chile. Just starting.
I bought 2 of your boards as a sample in order to evaluate the convenience of replacing original Arduino ones wich "used" to be higher priced. Not any more I have noticed....
Following your motto i.e. "We say NO to excessive profit !...."
As said in the title, one (1) of your boards connects ok and is recognized correctly by OS,s and Arduino IDE. (the bad one ) As well as the other one.( the good one )
The problems with this particular one (the bad one ) is that it will not complete the firmware uploading sequence.
After compilation, communication for upload commences, communications lights on board blink a few times but the process is halted after few seconds.
The Arduino IDE reports " coul not get in sync....."
Hence turning it useless in the reprap allround operation and tune up.
Again , same computer, same USB slot , same operator, same cable ,same everything.
The only difference I have noticed is that in Win 7 64 bit , the one Iduino mega 2560 is mounted as Comm 17 and the "bad" one as Comm 19.
Thank you

Re: Iduino Mega 2560 Connects but no Sync
hi Francisco:
from your description，i think the problem is that Serial communication failure.there are some ways to solve this problem。
1.PLS make sure that the board does not connect other device
2.when the firmware is uploarding，you should press the reset button。
3.reload the firmware

Dear Sir,
obviously , tour comments/suggestions did not worked at all.
Before throwing your board into the trash can, i , just for fun, connected to the faulty board using Repetier Host software.
To my surprise, the board answered and connected ok with following log :

As you can see, this particular board ame with an Firmware already written into processor memory.
It is NOT the firmware I use, nor am I "Jack", autor mentioned in the log text.
I am NOT able to load ANY other firmware obto this board, Not even Arduino BAsic "Blink" program
It is clear to me thas this particular board has been tampered with before shipping.
I have tried to burn a new Bootloader onto the board following "Arduino as ISP" instructions ( in this case Mega 2560 to Mega 2560 ) , with no positive results
Please your comments

Re: Iduino Mega 2560 Connects but no Sync
so,maybe the atmega16u2 is broken,you can change the new atmega16u2.
All of Geeetech products have undergone first rigorous testing and second sampling inspection by professional inspectors.
It is almost impossible for us to ship you a defect driver. But it may be caused during transportation.As you know international transportation is hard to control, the package may not be treated friendly or handled improperly on its way to you. And the static electricity may cause short circuit,which is deadly for the chip.
I suggest you to contact the seller for further solution.

Re: Iduino Mega 2560 Connects but no Sync
Hello,
I have just finished building me GEEETech I3. I am having the exact same problem as above. I My computer can see the COM but i am unable to upload. I have a second Arduino Mega which i can upload to just fine. Was a solution ever found for this problem or is the iduino Mega r3 to far gone?
On another note the LCD display that i received with the kit also is faulty. I tested it on 2 other printers and in both cases the selector knob doesn't work.
