K64 bootloader Hardfault interrupt issue while flashing

Question asked by niranjanbc on Sep 9, 2015

I am using below boot loader example


I am working with K64, using Code Warrior  10.6

the boot loader loads the app and work fine with simple small project led_blink.

but when try to load my application project srec file which is pretty big, I am getting Hard fault interrupt after some half the file is loaded.

after debugging using Hardfault processor component, I see it is Fault address error "Precise data bus error" bit set on SCB->CFSR register. I do see fault address loaded in the register SCB->BFAR.

do you know what could be causing this.
