CANBootLoader application in mpc5606b

xy387 — Thu, 17 Mar 2016 02:05:08 GMT

I want to tell the linker to build for the starting address of the intended AppSlot,so I made some change in my link file ,but it does not work ,and my program dead. by the way, The MCU I used is MPC5606B, The IDE is CW10.6, I do not know where is my problem. Anyone could tell me where is my fault. I appreciate all your help,Thank you very much.

This is where my change

resetvector: org = 0x00010000, len = 0x00000008

init: org = 0x00010008, len = 0x00000FF0

exception_handlers: org = 0x00011000, len = 0x00002000

internal_flash: org = 0x00013000, len = 0x000ED000

This is my original link file

init: org = 0x00000008, len = 0x00000FF0

Hi,

take a look at:

https://community.freescale.com/message/427962#comment-427962

I described how to create projects for application/bootloader in chapter 2.
