I have a board of SPC560B. I need to make a BootLoader.

I want to do that:


the JMP_ADDRESS is 0x40000

PowerON--> running BootLoader at 0x000000 in flash.--->delay 3000ms-->if (update cmd ==false)-----> 

 (*(AppFunctionType)(JMP_ADDRESS+8))(); // jump to app and should not back

Is that ok?


Why do all people develop BootLoader in RAM for MPC5XXX?

Can't BootLoader be run in Flash for SPC5XXX/MPC5XXXX?
