How to run application by boot loader

Hello everyone.

First of all please forgive me my bad English.

I'm quite new to programming microcontrollers never the less i'd like to run a boot loader, that loads an application on LPC11u68.

Let's say I want to locate demos_switch_blinky in flash at 0x2000 and want to execute it by running a boot loader. Am I right to store 0x2000 in VTOR-register, update sp and finally branch there? Like this:


ldr r0, =0xE000ED08 /*VTOR*/
ldr r1, =0x20000 /*base adress of application in flash*/
str r1, [r0]
ldr r0, [r1]
mov sp, r0
ldr r0, [r1, #4]
bx r0



But how can I locate an application at a certain address in flash with lpcxpresso explicitly?


many thanks for any help in advance
