How to generate a reset via software for MPC574xR?

[umsteigen]

Dear Freescale,

I want to generate a reset via software to enter the bootloader, how to?

Do you have sample code?

Thank you.

Hello,

This is quite simple:

Use mode transition to reset state. Functional or destructive.

    //Mode transition
    MC_ME.MCTL.R = 0x00005AF0;              //Functional reset Mode & Key
    MC_ME.MCTL.R = 0x0000A50F;              //Functional reset Mode & Key

or

    //Mode transition
    MC_ME.MCTL.R = 0xF0005AF0;              //Destructive reset Mode & Key
    MC_ME.MCTL.R = 0xF000A50F;              //Destructive reset Mode & Key
