Hey Dranne,

Drivers are provided for the device for flash programming and EEPROM emulation.

You can download them and the documentation from the website. From the home page - > 32-bit MCUs -> MPC55xx --> MPC5554.  Select the software and tools tab. You will find the drivers you require here. There are apps note and other resources available as well. .

Referring to the MPC5566 ref manual, Page 13-26 gives a step by step guide on how to do this.

I want to do In-Application programming of flash, also EEPROM emulation, can you please help on this. Any sample codes or application notes?

Thanks in anticipation.

No not really, apart from pointing you to the app note from Freescale.

[dranne]

Can you please give me the application note. I'll be very thankful.

Also please tell me if I want to run the application from the internal SRAM, how can I do that, I mean program the flash with the application code, then at run time the application is copied to SRAM and execute from there, any idea.

Thanks in anticipation.
