I am trying to program blink_led in custom board ATSAMD21E16A using ATMEL-ICE programmer in Arduino IDE,
I have changed the board.txt i.e :boardname.build.ldscript=linker_scripts/gcc/flash_without_bootloader.ld,
variant.cpp, at91samdXX.cfg- changed the controller from ATSAMD21G18A to ATSAMD21E16A.
After changing all these i got the below response.

LED is not blinking. I am guessing that program is not uploaded correctly?
So is ATSAMD21E16 is compatible in arduino IDE, if yes what other changes i need to do, Please advice.
Thanks in advance.
