Hi,

I want to use RAppid boot loader for MPC5777C, please guide me do whether do I need to set BOOTtCFG fies as serial prior, or RAppid boot loader will take automatically.

Please guide me how to generate rbf file with S32DS and lauterbach tools.

Sorry,

I am not familiar with Rappid nor S32DS.

You should look into Rappid documentation if BOOTCFG is required to be set.

Hi,

This is quite simple, and it is also described in reference manual Chapter 5 Device Configuration Format (DCF) Records.

For reference I have attached simple DCF programing Lauterbach script.

Additionally we have posted here on community DCF calculator tool which is free to download.

Hello,

I strongly recommend you to read DCF record chapter in reference manual before any DCF operations.

DCF is located in UTEST memory which is OTP.

here is the DCF record update procedure:

You have to add new record with updated values.
