New linker warning (warning: Empty loadable segment detected, is this intentional?) in LPCXpresso on C++ multicore projects

We have noticed this linker warning (in only the M0 build) after switching over to the 7.9.XX versions of the tool. Does anyone know how to troubleshoot it? There is very limited information through a google search on this warning, and it seems like no one else has documented it in the LPCXpresso toolchain. I've replaced the project file names with XXXX_m0.

We haven't found anything terribly wrong with the way our code runs (yet). I assumed it was a result of some change that had been made to the LPCXpresso toolchain, but wasn't sure how to confirm it since there was so little information online about it. One thing we did change on our side after upgrading to the new tools was to use Freemarker linker scripts. I wanted to be reasonably certain before our release that the changes we made with the linker scripts have nothing to do with that warning.

So, many thanks to your support in looking into this. Perhaps now you have enough information to pass along to prevent a future release from emitting the warning needlessly.

Thanks again.

Ok, so this warning message seems to be being triggered in some circumstances by the removal of the .bss sections that LPCXpresso now carries out in creating the object file version of the M0 image. [As the M4 doesn't need these when creating the overall combined image - as the M0 image will dynamically create the bss area(s) as its startup code executes once the M4 releases it from reset.]

As far as I can tell the warning itself is completely benign and can be ignored. Can you confirm that your combined M4/M0 application functions as expected?

LPCXpresso Support

Hi, thanks again for helping me with this. I've been developing since then in the m4 core, so the m0 core may have rebuilt as a result of a few of my changes, so I'm resubmitting both of the dissassembled files. However, I don't think any changes in my link line would be significant enough to repost.

Sorry, I forgot to ask previously - can you also post the contents of the disassembly of the *.axf.o" file generated (in addition to the *.axf).

I can't replicate your problem using a newly created C++ set of multicore projects.

Please can you post the whole of your link line. This will include the command that is being used to convert the M0 AXF file into an object file that can be linked into the main M4 image. It is this "arm-none-eabi-objcopy" conversion command carried out as part of the link step that is triggering the warning.

I suspect that we will also need to see your M0 axf file too. Can you ZIP and attach this?

If not, then please can you at least disassemble it, and post the first part of it (up to the "SYMBOL TABLE:" marker).
