warnings during linking: undefined symbol fs_data$$Base and fs_data$$Limit

[littlebei]

I was just working with the ble_app_uart example in nrf5_SDK_12.2.0. Minor modification were done to the main function. The build output:

linking... ._build\nrf52832_xxaa.axf: Warning: L6330W: Undefined symbol fs_data$$Base (referred from fstorage.o). Unused section has been removed. ._build\nrf52832_xxaa.axf: Warning: L6330W: Undefined symbol fs_data$$Limit (referred from fstorage.o). Unused section has been removed.

I have no idea what they mean and how to deal with. It seems they don't have much impact on building the target, but quite annoying……Is there any solutions?

Are you using gcc to compile the example? If so could you attach the linker script (.ld file ) your're using?

I have the same situation but I use KEIL MDK and I don't know how to solve this problem now. I hope you can help me

Please open a new ticket and attach the build output from Keil in the ticket. Also state which SDK version you are using.
