Hi hjhjhj‌,

If you are looking for the linker generated symbols, you can find them in 

can_simple_block.map file:

Hope this helps!

Razvan.

Hi Razvan，

     There're the symbols' address in the can_simple_block.map file,but what I want to find is the place where the symbols are defined.And I try to use the symbols in other files,which is the reason why I must find their derivations .Do you kown the files where the symbols are defined?

Thank you!

Hi hjhjhj‌

Those symbols are defined in the linker command files (aka linker scripts)

To access them from the other C-source files is quite easy: please check this out:
