blink on mega2560: avrdude: verification error

Using Arduino Microcontrollers
1

Hi experts,

I always get the verification error, no matter which sketch I use. The function seems to be ok althought I get the verification error.

I tried the bootloader from this topic (#12) but I stll get the verification error.

AVRDUDE Checksum Fail on MEGA/UNO - Microcontrollers - Arduino Forum

Any idea how I could solve this issue?

Using arduino ide 1.6.5-r2 on win7

Sketch uses 1,518 bytes (0%) of program storage space. Maximum is 253,952 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 8,183 bytes for local variables. Maximum is 8,192 bytes.

avrdude done.  Thank you.

Thanks for your help,

Have already test in another computer?
Are you sure that your Mega is using the COM6 ?

It is not very bad, most of the communication seems to be okay.
Perhaps the voltage is low. The ATmeg2560 needs more than 4.5V.
Do you power the Mega board only with a USB cable from a laptop ? or do you use a cheap usb cable ? or a hub (a hub that is not powered) ?

Try another computer or another usb cable or other usb port. Or try a power supply 7.5V to 9V to the power jack.

Is it a cheap clone with bad quality components ?

The avrdude command seems correct.

seems fishy. Why a checksum error?
