non init section

[Canastra]

Hi

In  other toolchain with GCC it is possibility to move some variable to a non initialiseed section

__attribute__((section(".non_init"))) int buffer[1000U];

When I use this with SES and zephyr I get 

orphan section `.non_init' from `app/libapp.a(HAL_Gpio.cpp.obj)' being placed in section `.non_init'

Is there a solution with SES and zephyr?

Thanks

Hi,

Try using __noinit , e.g. as done here: https://github.com/nrfconnect/sdk-zephyr/blob/v2.6.0-rc1-ncs1/samples/boards/nrf/system_off/src/retained.c#L130

Hi,

__noinit is the solution. Thanks.

Is there a option to generate a map file.

So I can check what is in which segment?

 Check the build folder. <sample>\build\zephyr\zephyr.map

Hi Sigurd

Thanks.

Now I see my object is in the noinit section.
