Hello !
I´m working with the board DEMO9S08DZ60 and I need preserve the eeprom data when I reprogram the project.
I try to SET in the programmer -> MultilinkCyclonePro/ AdvancedProgramming / Always Preserve All EEPROM Data or same range of them .. but DIDN´T WORK !!!

I try with the forum of P&E ... but, it don´t work or i can´t do a search !!
Excuse me for my english.
Thanks, Jose.-

Hi,

Now I am not a C-guru at all, I have not tried it, but I would use

const unsigned char data[64] @EEROM

and then use.

But as I said, I haven't tried it myself, so it might not work at all.

Regards,

Ake

It works for me, using CW6.0. If you are using the same version, you should post a service request at the Freescale site.

He is asking for how to prevent the debugger from erasing the eeprom each time he loads the project.

Hy Lundin,

You have reason ... the problem is how prevent the debbuger to erase the eeprom.

I found this theard http://forums.freescale.com/freescale/board/message?board.id=CW816COMM&message.id=1112&query.id=102829#M1112
it´s explain how edit the xxx.S8P file to preserve the EEPROM !!! That works for me !!!

But, I wiil try again with the setting of MultilinkCyclonePro/ AdvancedProgramming

Thanks for your help.

Regards, Jose.-
