Controller : STM32L476QE
Compiler: arm-none-eabi-gcc.exe (GNU Tools for ARM Embedded Processors) 4.7.4 20140401 (release) [ARM/embedded-4_7-branch revision 209195]
Program end into hard-fault handler before even breaking to main
Removed previous log, as i think its problem while flashing.
We are using JLink Lite to flash the stm32l476qe , and if binary size is greater than 256K it gives below error

I raised same request in J-Link segger forum
http://forum.segger.com/index.php?page=Thread&threadID=2899
I don't know this problem is from Jlink side or STM32L476qe side, can anyone please provide input, so that we can proceed in right direction? It would be great help.
