I  took  the hex and i upload it on board with a programmer  ( stk 500 )  on chip mega 2560  with isp.       It is ok!!!!!!!!.



When you upload a sketch via isp then it will overwrite the bootloader.  You probably have no bootloader on the mega 2560.  You will need to put back the bootloader.

SERET

Thanks all of you.
I replace the bootloader on  secont chip 2560 via isp. Now it is ok.  There was:
