I want use ATSAM4E16E in LQFP144 package in my custom board. I have a Atmel-ICE tool and the chip will be programmed via JTAG. I measured all voltages, MAIN is 3.28V and for core is 1.22V. But when I tried to Read ID or anything else it writes me this:
Could not activate interface, but found DAP with ID 0x5b3703f.
and these things about security bit...
I tried to erase chip with ERASE pin as its described in datasheet.
(RESET to 0, ERASE to 1, power on, 30 secs ... )
I am not sure if ERASE was succesfull but the problem is same..
Could anyone help me how to fix that ?
Thank you :)
