Hi, I have a some Q which is about flash resident bootloader.

i wrote jump function in bootloader project

======================================================

asm void SYS_Jump2App(void)

{

/* Load reset vector address */

lis       r3,0x0010
ori   r3,r3,0x0004
lwz   r3,0(r3)
/* move address to link register */
mtlr r3
/* branch link register - start the user application */
blrl

}

=======================================================

when i execute that SYS_Jump2App function after download Application via serial , it is not working

I saw PC value , it is 0010_01000 ...

example used SIU register.. but i wanna try another way
