hello everybody!

I have a two questions:

1) What are the three sections '.init' , '.text' , '.fini' in the linker script? what are the differences between them?

2) How can I know how match place needed for my code in order to avoid overlapping?

thanks a lot

The linker script controls the placement of the object code, data, stack, and heap in specific memory locations. Do u know what is an object file? it is an assembled piece of code ie in machine language.There few sections on it like .data (read wrte data section),.text (text section) etc

supoose u write

int data[10] = {0,1,2,3,4,5,6,7,8,9};...................this is .data /* DATA */

.

,

'

I = I + 10; /* TEXT */

like this... similarly

.init is Language initialization code & .fini is Language cleanup code

To know ur program size do,

1. Select Software > Get Program Size. The Choose a Software Application dialog box opens.
2. Select the project for which you want to view the program size.
3. Click OK.

regards

 just one thing more - I don't have a tab 'software', so how can I know the suze of the code?

[joy1887]

Software tab  must be in ur EDK software,which version u r using?

I am using EDK 11.1 and it is in it

I'm using EDK 13.2 and I don't have this tab

just click on build project, you can get the program size at console window(if you have sufficient memory for your design).

since 13.1 or 13.2 all software development tools and actions have been removed from EDK and are only accessible from SDK any more
