Hi there,

 

I can't start my application with boot header located in address other than

0x00F8C000.

 

Application examples (AN4830,

http://cache.freescale.com/files/microcontrollers/doc/app_note/AN4830.pdf)

boot header are all located in 0x00F8C000.

 

Reading MCU manual, it seems to be an issue with HSM module.

 

Consequently, could you please give more details about this:

* Is there any software example code with boot header located in address

other than 0x00F8C000 ?

* How must I proceed if I want to start my application in address

0x00FC0000 for example (this address is recognized by the BAF) ?

* How can I disable HSM (in MCU manual, HSM is always disabled at

power up) ?

 

I am working on automotive ECU with complex SW organization: BOOT +

BSP + APPLI layers.
