@AlessandroDevs interesting, looks like it’s trying to include CMSIS-DSP twice… I know Mbed Studio uses ARMCC underneath, perhaps that’s an issue? Can you try this: https://os.mbed.com/docs/mbed-studio/current/installing/switching-to-gcc.html ? Also, which Mbed OS version and target are you using?

I’ve just compiled the example against Mbed OS 6.0.0 on the ST IoT Discovery Kit with Mbed CLI and GCC ARM 9 and that compiles and links fine.

Good spot, it works with the latest GCC ARM 9. Thank you for such a quick answer, appreciate it! I need to look into why ARMCC is instead doing that :slight_smile:

Yeah interesting behavior. Compilation actually works but then linking fails… If you manage to get an idea please let us know and we can fix this in the SDK.

Hi,

I prefer using MBed studio.
I switch from GCC_ARM to ARMC6 toolchain.
I get no compiler error.
I get the same linker warnings as @AlessandroDevs.
It builds the bin file here.

Object file arm_bitreversal2.o is not unique! It could be made from: edge-impulse-sdk\CMSIS\DSP\Source\TransformFunctions\arm_bitreversal2.c edge-impulse-sdk\CMSIS\DSP\Source\TransformFunctions\arm_bitreversal2.S

The Object file arm_bitreversal2.o is not unique! is related to your SDK.

Example works like a charm on the board.

Hope this helps.

@HaraldBlab thanks for letting us know. I think the warning is fine for now - that file ships both in Assembly and in C format, not sure why CMSIS-DSP is doing that…
