Hello everyone! I tested with the new Atmel ICE Basic with my device and after press the debugging button. It starts writing and stops at 95% "Loading symbol info". Then an error box pop out saying "Failed to launch program", "Failed to leaveprogmode." Does anyone know where the problem lies? Many thanks!!!
That's an old post. But I answer because it may help others who find this question by web search... You should check that the RESET line is not active (low). If you have an ISP interface connected to a programmer or another microcontroller that can act as programmer, it will hold the RESET line active to allow programming. The JTAG debugger is not able to start the AVR and reports "Failed to leave progmode" under this condition.
