Hello, I m using YAGARTO Tool to compile my code for CPU-AT91SAM7X512. This tool provide ECLIPSE as editor and GCC VERSON 4.2.1 as compiler. I developed one project which is consuming code memory around 265KBytes and 33KBytes of RAM. When i m runing this code it works ok. Now i add other .C & .H files. But i m not calling any function or not using any variables out of these last added files. I just add these files in project and then compile those files. But i m not using any file out of last added files. Now when i run, succesfully build code on cpu it executes some part of code and than what its doing not able to understand. When i debug code i found that when it find devision operation, than cpu will go somewhere else and not run next remaining code. After adding .C & .H files my code size becomes around 353KBytes and RAM around 66KBytes. So, i want to know why my code is not running proper if i add others .C & .H files, even i m not using those files in my code ? I need those last added files but right now i just compile those files. I think there may be some MAKEFILE problem. Because right now i found that i just compile code not using added code. So, just compilation make this difference.
>------------------------------------
I am not getting solution. I add optoin "-ffunction-sections","-fdata-sections" in compilation. After adding this option it is generation 0Kb of BIN file. But I dont want to remove unwanted code. So, i remove above option. Because i will use those code afterwords. I am getting Undefined Interrupt when exectuing devision statement. I don't know why interrupt occuer. Because my code compile ok. Even before adding extra unused file, my code is working well but after adding .c & .h files it gives Undefined Interrupt at executing division operation. In division operation i m dividing WORD(2 Byte Unsigned Data) with 1000.0 and saving result in float type variable. I also tried with adding float cast for WORD variable.
So, why before adding other files devision works and after adding other .c & .h files, devision gives Undefined Exception Interrupt(0x04).
