Modify start address in MQX project with Keil uVision4

The bootloader is programmed from 0x0~0x9FFF.

Application is programmed begin from 0xA000.

After bootloader programming the application, it will jump to 0xA000.

So, we need to modify the MQX application project to begin from 0xA000.

We've modify below settings.

#define BSP_INTERNAL_FLASH_BASE 0x0000A000

#define __VECTOR_TABLE_ROM_START 0x0000A000

#define MQX_ROM_VECTORS 0

We also modify the .scf file with below value, original is 0x00000000.

#define INTFLASH_BASE_ADDR

0x0000A000

The map file seems ok, but can not execute the application correctly.

.vectors_rom	0x0000a000 Section	1024 vectors.o(.vectors_rom)
__tagsym$$used	0x0000a000 Number	0 vectors.o(.vectors_rom)
.cfmconfig	0x0000a400 Section	16 vectors.o(.cfmconfig)
__tagsym$$used	0x0000a400 Number	0 vectors.o(.cfmconfig)
!!!main	0x0000a410 Section	8 __main.o(!!!main)
!!!scatter	0x0000a418 Section	52 __scatter.o(!!!scatter)
!!dczerorl2	0x0000a44c Section	90 __dczerorl2.o(!!dczerorl2)
!!handler_copy	0x0000a4a8 Section	26 __scatter_copy.o(!!handler_copy)
!!handler_zi	0x0000a4c4 Section	28 __scatter_zi.o(!!handler_zi)
. text	0x0000a4e0 Section	76 boot.o(. text)

Did we miss some configuration so it can not be executed correctly ?

Please advise, thanks.

I think you need to change the following, INTFLASH_BASE_ADDR, _VECTOR_TABLE_ROM_START, and mark //init_hardware->_bsp_initialize_hardware->_bsp_watchdog_disable()

There is an application note AN2295 for that.

thanks for the reply.

Currently it seems ok now.

We have another issue.

We add a library which is compiled also using Keil uVision4.

It seems that in the application, when called the function in the library,

it can not be executed correctly,

any idea ?

Thanks.
