HERE IS THE SOLUTION... 1. Project Settings in IAR for Banking Scheme (data model, etc..) 2. Keeping the core part of the code in ROOT CODE memory using "__near_func" attribute. i.e. main(), low level initialization functions 3. Modification of the linker file as suggested by Compiler reference guide for banking system. 4. VERY IMPORTANT: replace the original startup code (which is for non- banked model) with the banked model startup files found in the tools installation directory. This is done by including the files in the project (Project ->Add Files). 5. Read the references for more info... Thank you All... Amir
