ROM Size problem in nRF52833 with nRF Connect SDK

[Kawingwu]

Hi, 

there is my project rom size in memory report , I would like to asking what is the "NO Paths" item and hidden item

 they hold my 20% ROM size. and what is the content in Nordic Proprietary Libraries. it also take 25% rom size. 

since I need to add a new storage zone (around 16kB) for data storage, but my rom size is almost full by library and stack ,

I cannot reduce the image size , How can I reduce the libraries size and the stack size. ?

Its the stuff (softdevice controller) that actually runs the BTLE radio.

Your estimated 25% of about 200KB sounds correct to me when running peripherial mode (central/multirole would fill up the entire partition).

Consider a redesign: Either use external flash for the firmware update or the bigger NRF52840 chip with twice the internal flash.

it so worst, then how about the hidden item and no path item? they take around 22% rom size , if there are no other solution to reduce the rom size.  new sdk is very limited on small flash size Nordic SOC. but 512KB is large in size.
