kernel sections
Posted: Sat Nov 29, 2003 10:35 am
Here is my linker script:
and in my kernel, I print out the section start and end point location. Here is the results:
What locates between 'Kernel End' point (10FF0) and 'End of Bss section'(10E00)?
And I get the end of kernel with EndOfKernel symbol, how can I get the start point of kernel?
And as a last question, are these sections lies in binary file as the order I put?(text, data, bss..)Or is there any order of sections?(First section must be text, than data...)
Code: Select all

Code: Select all
Text Section : 9000 - CA00
Data Section : CA00 - CC00
Bss Section : CC00 - 10E00
Kernel End : 10FF0
