With any of the optimization levels (-Os size/-O1 general/-O2 speed/-O3 fast) except -O0 none, bootloader is not jumping to the application code.

Hi,

I am working on SPC58NG84E7 bootloader. I have BL code(at 0xFC0000) which jumps to the APP location 0xFD0000 after waiting for 10sec after startup and executes the code there. Both codes have optimization NONE(-O0). 

But when BL optimization changed to -Os size or any of the mentioned, BL is not jumping to the APP and continuously running the BL code.

What could be the issue here?

@AVM​ ,

Think about an optimized variable(s) and use volatile ..
