Debugger EEPROM-Read S12ZVML128

Hi,

 

we are using PE-Micro Multilink Universal for Debugging in our development.

When we read the EEPROM in the memory-view in Codewarrior the first 72 bytes of the EERPOM will be returned as zero even when data is written into the memory area.

 

When we use the Onboard-Debugger of the S12ZVML12EVBLIN Eval-Board the EEPROM is returned correctly. For tests we use the BDM interface of the EVAL-Board and connect with a Multilink Universal Debugger and wrong data is read (0x00).

 

The Bus-clock is configured to 50 Mhz, the FCLKDIV to 0x31.

 

Are there any known bugs or special debugger settings necessary to read the EEPROM?

 

 

Regards


Axel
