Good morning.

I have already seen this topic

 

 

usb BDM. How to program flash & leave Eeprom as is

 

but in my casse it doesn't work.

 

I want to debug my firmware with Cyclone Pro and I use Codewarrior 5.9.0. I want to preserve my EEPROM data

 

I deleted this entry in Mcu03CB. fpp file :  MODULEIMPORT MC9S12_EEPROM_EETS2K_W_HIDDEN          -> EEPROM is blanked and debugger doesn't work correctly = program doesn't run

 

I deleted Mass erase EEPROM section in erase_unsecure_hcs12 -> debugger doesn't work: it seems to program the micro but debugging is impossible and program doesn't run

 

In debugging Memory map, in CyclonePro Menu (Truetime simulator) I set EEPROM entry active = NO   -> there is no effect

 

With Cyclone PRO I load SAP Image but the algorithm for MC9S12A128B hasn't got "Protect EEPROM " command

 

I inserted in Startup script AEFSKIPERASING command but it doesn't work

 

 

Can you help me?

 

 

Thank you very much
