MK64FX512VLL12 Custom Bootloader related

Question asked by Neha Beknalkar on Mar 2, 2017

Hi,
I am trying to make custom bootloader firmware using MK64FX controller, for this i have modified the linker files for both application and booatloader firmware. For this changes i had used "DFU_PC_Demo" source code.

 

By using bootloader firmware i can erase all flash sectors (512KB) without any error.

 

I am using FTFE flash module for programming flash sectors, i after programming 68KB of firmware, i am getting "ACCERR" error in "FTFE_FSTAT" register, but still all firmware is downloading without any error.

 

After complete download of firmware , i couldn't jump to application firmware location (0x16000) , I am getting 'no source available error in debug and sometimes go to "Default handler".

 

Kindly suggest necessary changes required for remove access error and switching program counter to Application firmware location.

From,
Raviraj
