Hi all, The Overlay mechanism implemented by Keil is ingenious. Moreover if we want add some functionnality in Eeprom without change ROM code is to my mind impossible because DATA GROUP area will be modified with new local variables used in our new functions in Eeprom. What do you think about this? Thanks a lot, Daniel
Hi Daniel, Split your Project into two. One for your ROM and one for EEPROM. After generating ROM-Project look the used resources in DATA, XDATA etc. These had to be excluded from EEPROM-Project. And for using functions in EEPROM use adresstabel with entrypoints. Chris
