Hi Parag,
but, GCC linker is not doing this, it is also giving load addresses , so my sections are overlapping.CAn I tell compiler that don't give loadtime addresses, but only to give execution addresses?
No, but you can make sure that the load address for the .bss section does not overlap any others. What is the linker map that you are using ? Also what command line are you using to create the executable ?
Cheers Nick
