JUMP Problem when using RTX RTOS

LOST ISLAND

Hi all ,

Using Uvision4 & LPC1768 & RTX RTOS ,
I want to jump to 0x10000 of the flash.
Before running RTX , there is no problem but after using os_sys_init(APP_TaskStart) , when trying to jump , there is a hardfault . How could I jump while RTX is running ?

By the way , Is there a way to disable RTX ?

    Are your boot loader _really_ so advanced that it needs to run an RTOS?

    RTOS has its place, but I have seen more cases of a RTOS used where it should not be, than cases where a RTOS was not used but should be.

    also a very complicated bootloader is more likely to suffer from the one unexcusable bootloader fault: "If power fails at point x, the system is hung".

    ANY bootloader that can not be restarted if interrupted by ANYTHING such as noise, power failure or whatever is a piece of crap. The criticl place, of course, is the transition from boot to app.
