relative path of distant library in linker command file

SamP

Hi,

to start, I have read https://e2e.ti.com/support/development_tools/code_composer_studio/f/81/p/113303/403579#403579

This gives me hope that what I want to do might possible. I am trying to put the .text of a .lib file based off of a symbolic path in an output section. I can link this into the project with the symbolic path:

${CC26XXWARE}/driverlib/bin/ccs/driverlib.lib, where CC26XXWARE is defind in the project's linked resources as C:\ti\tirtos_cc13xx_cc26xx_2_16_00_07_eng\products\cc26xxware_2_23_01_16780, the common parent folder between the CCS project and this library would be C:\, and the project folder of the CCS project could be at an arbitrary depth.

I would prefer not to link this .lib in my linker command file by its absolute path. Is there a way to do this?

Thanks,

-Sam

You cannot directly refer to a CCS variable from within the linker command file. But I don't think you need to. You could add something like ...

${CC26XXWARE}/driverlib/bin/ccs

... to the list of directories searched by the linker (see screen shot below). Then you can use the methods described in the section titled Specifying Library or Archive Members as Input to Output Sections of the ARM assembly tools manual.

Thanks and regards,

Thanks George! this fixed the problem.

A little backstory, the reason I am doing this is because I am building an image which maps into 2, non-contiguous 4KB flash pages. By itself, the linker cannot break apart the .text section into smaller chunks and link into the 2 pages (the .text the linker creates itself is greater than 4KB). Is this expected behavior, or am I dancing around an unaddressed corner case of the linker?

Thanks!

It can if you use section splitting. Read about that in this application note.

Thanks and regards,
