Hi Thooman,
Thanks for your reply.
I‘m afraid that MCU couldn't work normally after you corrected define symbol __ICFEDIT_region_RAM_start__ = 0x0;
I've corrected the ICF again which show as follow. And you also need to make the instructions which are used for copy the vector table to RAM don't operate in common_startup(void) function.
Please give a shout and update me instantly when you get result.
