Bootloader for MPC5748G

[tiju]

Hi,

I can see a 'BootLoader_MPC5748G' example in S32. It compiles successfully.

"BootLoader_MPC5748G.elf" and "BootLoader_MPC5748G.srec" is generated. Bit I do not see a binary.

How to flash the bootloader to devkit? And what is the expected output?

Also can you throw some light on what kind of bootloader it is?

Thanks and Regards,

Tiju

Hi Tiju,

Can you please share the serial bootloader code zip for the MPC5748G as I am unable to find it in the S32DS or MCU expresso IDE. Maybe they have removed it from SDK example codes.

It would be great if you share the zip at sood04sonny@gmail.com

Thanks

Tiju, 

There is txt document - description which explains this boot loader.  

You need have openSDA interface for your hardware to get this boot loader working.

Hi Udit,

I am looking for a bootloader that can run directly on MPC5748G without using OpenSDA. Can you help me with that?

Thanks and Regards,

Hello,

The bootloader example project "BootLoader_MPC5748G" is the template project that demonstrate how to use RAppID Bootloader with MPC5748G DevKit and S32DS.

For more details about the bootlader and it's features I'd recommend you to see the document below:

http://www.nxp.com/files-static/training_pdf/FTF/2014/americas/WBNR_FTF2014-AUT-F0014-B_PDF.pdf 

First you need to program /rbf file which is actually the bootloader binary. This could be done by OpenSDA (see the screenshot below) or any other Debug cable you have (PEmicro Multilink, Universal, FX..)

There is pre-configured debug configuration that loads the bootloader binary:

Then you can build the Application which basically blinks LEDs on the board. The generated project + its SREC is located here:

Now download install and run RAppID Bootlader utility:

(https://www.nxp.com/webapp/Download?colCode=RAPPID_BOOTLOADER_UTILITY&appType=license&Parent_nodeId=... )

you should be now able download the generated application project (s-record) via Virtual COM over USB cable (COM15 on my machine) into the board.

Hope it helps.

Hi!  I am trying to follow Stanish's instruction to try the BootLoader_MPC5748G example on my DEVKit-MPC5748G board.  But I got the following error when trying to flash the BootLoader_MPC5748G.RBF to the board.  Could someone please help me?  Thanks!
