How to program eeprom using code warrior 5.9 tools or any others tools

Hi,

my microcontroller is MC9S12DG128VFUE and we have code warrior 5.9. How to program the eeprom or erased it ?

Please see attached demo code.

It's for DP512 but the method is the same as DG128.

Hope this will help you,

Is it possible to use WL command from Code Warrior Debuguer instead. Why it doesnt persist after reboot?

Besides the demo code method, you can define a const data in EEPROM address. The const data are burned to EEPROM during download the code.

BUT, you can't revise EEPROM with debugger tool.

Hope this helps,

prog12z is P&E programming tool. As I know It can program eeprom. If you have any question regarding to prog12z, please contact P&E community.

Hi,

to connect to the device, what gnd and vdd should I use ? I am measuring 2.9V on VDD1 is it suffisiant ?

Your follow up question is no longer about CodeWarrior. Please create a thread to 16bit MCU space.

The 16bit HW engineer will help.

Thanks,
