ATSAM4LS2A power up does not boot without SAM-ICE JTAG

Fri May 09, 2014 9:48 pm

Hi,

I have a board which is using the ATSAM4LS2A processor. If I using the SAM-ICE to connect to the JTAG debug port and start running the program (Start debugging and Break or Start Without debugging), the program starts and run without any problem. However, when I remove the SAM-ICE JTAG debugger, and power up the board, it seems like the CPU does not run or start at all (From the serial port, nothing happen). Can someone please help me what can be wrong or if there are any pins around the chip are holding up the CPU from running.

Thanks
