hI,everyone,I'm design an easy uart bootloader on KL14,the test bootloader has only jump code ,which is bellow:
// relocate vector table
SCB_VTOR = RELOCATED_VECTORS;//0x10000;
// Jump to user application
JumpToUserApplication((RELOCATED_VECTORS),(RELOCATED_VECTORS+4));//*(unsigned long*) //*((unsigned long*)
msr msp, r0
msr psp, r0
mov pc, r1
but it almost never works. I said almost because once it works,it succeed in jumps to where my application locates and it works! but one day later,after some flash changing,
I can never make it work again.
SO now,I wonder if it's because my scf file which decides my code's placement under KEIL.
I want to locate it in 0x10000,so I move the userapp's bin file entirely to this address.
Is it ok?or how should I modify it?
Really appreciate your help,I've worked for a whole week!
