HI CJChang,

can you try to use the attached flash_placement.xml file?

devzone.nordicsemi.com/.../flash_5F00_placement.xml

In order to help you I need the entire project folder so that I can compile and debug the project. I cannot do that with just the hex files.

Best regards

Bjørn

Hi bjorn-spackeli

Thank you.

I had a compiler error before, and I reference below link to modify the flash_placement.xml file, and compile success.

But I found that will work abnormal when FDS read or write. ( i.e., fnGetFlashData() in main.c )

https://devzone.nordicsemi.com/f/nordic-q-a/12029/segger-embedded-studio---unplaced_sections-problem

add <ProgramSection alignment="4" load="Yes" name=".fs_data" />

attach is my project folder, bootloader and softdevice.

Thank you for your help.

HI CJChang,

The Section Placement Macros look correct, can you post your flash_placement.xml file? ( Should be located in the same folder as the .emProject project file)

It sounds odd that initiating a FDS write or read should affect logging or the GPIOs. Would it be possible for you to upload the project folder so that I could debug the issue?

Best regards

Bjørn
