The uC starts the communication sequence but show the mensage
"Unable to communicate. (transmit/receive)"

Andy Ayre:
What have you tried and what were the results?

Waldir:
Thanks Andy!
I am using two USB to USART connector. One is connected to the Fashtool another in docklight.
-> Set the Crystal Frequancy at 16MHz,
-> Put the ISP0 to ground;
-> Power on;
-> Load the .hex file and try to Start. (all other conf are default)
