I have manufactured three sample circuit_board . At begining test the crystalloid,VCC and GND seem OK!
 
But when I download a simple program,a error occured at 33% of "NVM Erasing and Programmation" window .
 
pop-up "Non Volatile Memory Control " window,
ERROR:Error while loading diagnostics algorithm to target system. The chip may be secured,or the derivative of seclected maybe wrong.
