Bootloader issues

frankkong — Thu, 22 Nov 2018 10:42:09 GMT

Hi,

I,m using the bootloader on S12ZVML31. The example is AN4723. I can't configure the CPMU now. All the redisters will become 0xee after CPMUOSC_OSCE = 1;(CPMUOSC_OSCE = 0).

What is wrong in my code? S12ZVM_Bootloader is my own code, AN4723 is the example from nxp.com

Thanks!

Hi,

The S12ZVM_Bootloader.rar file seems to be damaged, I can't open it.

The BDM module returns 0xEE for each data byte as a response to an illegal access.

Do you lose connection with the board?

Regards,

Daniel
