Hi,

Did you place .nrf_queue in the flash segment after .vectors?

This is the .xml file for the rng example provided in the SDK which should work:

I did some testing according to this URL（https://devzone.nordicsemi.com/f/nordic-q-a/12029/segger-embedded-studio---unplaced_sections-problem）, but it didn't help ；I have modified the flash_placement.xml:

added：

But did not help，thank you for your reply！

Hi,

I think you need to modify flash_placement.xml file
