How to set flash_placement.xml file for NRF5340?

[squwal]

Hi, all.

I would like to assign location address for some global buffers or variables in ram by using __attribute__ keyword.  And I have to add my section in flash_placement.xml file.

However, there is No linker Options in SEGGER project->opions->code  to locate my xml file.

Currently i am using:

SEGGER 5.30a Nordic Edition

NRF connect SDK 1.4.99-dev1

NRF5340

Similar issue is here: 

https://devzone.nordicsemi.com/f/nordic-q-a/62841/segger-embedded-studio-for-arm-nordic-edition-v4-52-no-linker-or-preprocessor-options

So how can I assign my variale address?

Thanks.

Hi,

The linker script is generated by the Zephyr build system when you use the nRF connect SDK, not by SES, and this is why there is no option to specify a flash_placment.xml file. Instead you can supply a custom linker script as demonstrated by the Zephyr code relocation sample

Best regards,
