Hi, If you have the "data from ...", it means that you certainly called the _fctcpy() function which copies a moveable code segment in RAM from its storage location in ROM. For more information, please read the _fctcpy() function in the chapter 4 and the "Moveable Code" in Chapter 6. Provided with the compiler, many link files examples allowing the user to use and build paged and non paged applications. Some can be used to fill up the pages automatically or manually. Finally, when downloading an application with Zap, you should check first: 1) Are you using the right cable (Multilink or Cable 12) ? And check also for the speed. 2) Maybe you need, first to erase the flask and/or eeprom before downloading the application. Should you have any question, do not need to contact us.

We are unable to load this program and we are getting following error message while loading this val.h12 thru ZAP.. "Error while programming flash in area <'.data, from' start address >" Also we are quite surprised by appearance of ".data. from" segment in the map file eventhough we have not specified in our lkf file. Could you please explain what is this and why this happens? Please also guide us in generating lkf file for multiple paged system (as our h12 file is more than a page)?
