Same here: "No paths" occupy 23.4% for me (120.1kB). From that "No names" consume 55kB! Would be also good to understand what's "Hidden"?

Some info would be nice how to evaluate this.

Hi,

If you try to expand the No Paths, it might give an idea of the function names etc. It might include some of the things that come as archives and which miss filepath information and hence it's "no paths".

Hi,

Apologies for the delay as I was on a long vacation. I will update here as soon as I hear from the experts.

Regards,

Priyanka

Hi Priyanka , did you get a response to this? I've got an application which is using only 3.45kB ROM for the actual application code, and 121.2kB NCS and 71.8kB in "No Paths" which is making things completely unworkable for having any space remaining for flash storage when I need a bootloader OTA.

I would like to know that too.

My 'Hidden' part is 24.82% and 'No paths' part (most of the application functions etc.) is 40.79%.

Are there any updates?
What does Hidden and No Paths mean?

Hi Lonardo,

I have reported this internally and will let you know as soon as I get a response.

Hi Priyanka,

I took the example from Add DFU support to your application and I added some modifications.

I have also realized that when I add some lines at the prj.conf the No Path memory usage increased drastically:

1. CONFIG_MCUMGR_SMP_BT=y increases around 62kb the flash usage in the No Paths memory report.

2.CONFIG_BT_CENTRAL=y increases around 45kb the flash usage in the No Paths memory report.

My prj.conf looks like this:

Hi Leonardo,

This does seem to take a lot of memory. Could you let me know which sample/application you have used so that I can try to replicate this?

Hi dear Priyanka,

As you will see in the image, there are a lot of small files.

Hi Leonardo,

Could you share a picture of the same after expanding the dropdown option for No Paths?

Best Regards,

Priyanka
