I am trying to develop my project with ATSAM3X8E microcontroller, which is from arduino due.
i have followed arduino due schematic for connection, and i getting proper voltages to every signal pin of microcontroller(as per datasheet).
But when i try to connect with atmel studio (with atmel ice programmer through JTAG) i am getting an error is “could not activate interface the device is in locked or in deep sleep mode”.
I have attached the picture of error.
after that i try to erase the chip by connecting PC0(Erase pin) to 3.3V for more than 220ms. But i am getting same error again.
Can anyone please help me in this case, I am trying to solve this from last one month, and i have try everything but result is same.
Thanks in advance.
