SAM3S-EK2 Atmel ICE Programming Issue

Thu Jun 26, 2014 12:14 am


I recently received a SAM3S-EK2 evaluation kit and I have not been able to successfully program it with the Atmel ICE debugger. I am using the Atmel ICE adapter to connect to the ARM JTAG port on the baseboard. In addition I am setting JP3 to erase the flash and clear the GPNVM bits. After doing this I am able to erase the flash, but I am unable to program. Programming always fails on the verifying step and outputs the following message:

Verifying Flash...Failed! address=0x400000 expected=0xb0 actual=0xff

I have been able to program the board using SAM-BA and then I can go into Atmel Studio 6.2 and debug the program. This is absolutely maddening though.

I hope someone can tell me that I am doing it wrong. I have been through all the documentation and cannot get the programming over JTAG to work.
