Bootloader Problem on kenetis k53

Garil — Tue, 30 Apr 2013 13:43:45 GMT

Hi Guys,

Im trying to implement the bootloader on my custom board with the Kenetis K53 MCU using MQX

im facing the the following problem : ""No source available for "0xFFFFFFFE (0xFFFFFFFE)() "" this is due to the change in the linker file.

SO IM NOT ABLE TO DEBUG MY BOOTLOADER APP

basically im just following the AN4370 document which explain stuff related to the bootloader and so on, im still in the first step i cannot event debug my

bootloader application due to the error above.

can someone please tell me where is the error in the below linker file, or why the above error occur?

WORKING

vectorrom   (RX): ORIGIN = 0x00000000, LENGTH = 0x00000400
   cfmprotrom  (RX): ORIGIN = 0x00000400, LENGTH = 0x00000010
   rom         (RX): ORIGIN = 0x00000420, LENGTH = 0x0007FBE0  # Code + Const data   
   ram         (RW): ORIGIN = 0x1FFF0000, LENGTH = 0x00020000  # SRAM - RW data

NOT WORKING



 vectorrom   (RX): ORIGIN = 0x0000A000, LENGTH = 0x00000400
   cfmprotrom  (RX): ORIGIN = 0x0000A400, LENGTH = 0x00000010
   rom         (RX): ORIGIN = 0x0000A420, LENGTH = 0x00075BE0  # Code + Const data   
   ram         (RW): ORIGIN = 0x1FFF0000, LENGTH = 0x00020000  # SRAM - RW data

beside these changes, i set the rom vector to 0 basically in the config file i have

#define MQX_ROM_VECTORS

there are some other change to do, do i have a mistake in the changes above, can someone make me understand how to change the linker file correctly?

thx in advance,

Wilson

Hello wilson garil,

have you looked into these threads:

Bootloader problem - changing lcf file causes failure

Debugging code starting at 0xC000

Particularly second link could solve debugging problem. Do you use CodeWarrior?

Hi Martin

Sorry, this thread have not been updated by me since i solved the problem base on the second link that you provided above
