I am using codewarrior. I need to aviod erasing of eeprom while falshing program.

I am seeing 2 things to do in IDE:

1. In .prm file i changed EEPROM area to NO_INIT from READ_ONLY

2. I am seeing DO_MASS_ERASE_AND_RESET in

   C:\Freescale\CW MCU v10.7\MCU\bin\Plugins\support\s12z\gdi\P&E\freescale_9s12zvh128_1x16x64k_all.s12zp file.


I think i need to change DO_MASS_ERASE_AND_RESET which is doing mass erase of flsah and EEPROM content.


What (command) i need to replace or add to avoid erase of EEPROM during flashing
