I am using a uVision2 and C51 compiler. I want to use code banking as my code exceeds 64K limit. how do I specify which part of the code will be in which bank(means which files to assign what bank) and which will go into the common area. Suppose I have assigned two files of the code to be in bank0. How will I know the size occupied by the files in that bank? Does the linker take care of the function calls if we specify some files in one bank and some files in another bank randomly?
