MPC5748,Serial boot

[MichaelSun]

Hi Support team,

I want to test serial boot function on MPC5748G. Cause i cannot only erase the flash, i try to delete the "boot header". If i understand correctly, if the BAF cannot find the correct boot header, it will not jump to user code. I write a program to delect the whole boot header from 00F8_C000 to 00FA_8000h. I have verified that  i delete the boot header successfully. But i don't know why when i reset the board,  it still jumps to the user code.

I use PPCProgrammer to erase the flash successfully. But there is a problem when i use RappID BL Tool. I don't know why the RappID BL Tool didn't work as expected. It didn't send the password , address and code size. It sent the "erase flash" command directly which should be sent after the program has been loaded into the sram.

I checked the RappIDBL user manual again. I found the .rbf file is totally different from .rba file. If i want to use .rbf file , i have to program the .rbf file first. Now i understand why the RappIDBL didn't work as i expected.

I have another question.  I have used .rba file for "serail boot" of MPC5604. I refer the .rba file as a demo code. But now if i understand correctly,  there is no demo code to be used for "serial boot" of MPC5748G. Am i right?

Hello,

Hmm, that must be something with your access rights.

As I can see the web page when I am signed in.

But there is nothing more then guide how to submit a ticket at nxp.com

You can simply go to nxp.com and do it without guide, there is no issue the process is simple.

Best regards,
Peter
