Link warning: "missing .note.GNU-stack section implies executable stack" in STM32WBA52KE project

[Filippo13]

Hi,

I created a new STMCubeMX project based on STM32WBA52KE and when I build the generated code in CubeIDE, I get this error:

STM32CubeMX v6.13.0

STM32CubeIDE v1.17.0

FW_WBA v1.5.0

Can you help me please?

Thank you.

It's not an error - it's just a warning:

Perhaps @STTwo-32 can update on progress of "internal ticket:177107" ... ?

Hello @Filippo13 , @Andrew Neil 

This issue is fixed with STM32CubeIDE 1.16.0: STM32CubeIDE:STM32CubeIDE errata 1.16.x - stm32mcu

Resolution confirmed in this post: Solved: Error in building BLE_HID_Mouse example. - STMicroelectronics Community

@Filippo13, it seems you are using STM32CubeIDE version 1.14.0 when reviewing your warning.

Please update and make sure to use the latest release STM32CubeIDE 1.17.0.

Please keep us informed about your update and close this post if this issue is resolved for you.

I updated STM32IDE from v1.14.0 to v 1.17.0 before generating the code. That's why you notice "1.14.0" in the path.

Anyway I suppose this is an error:

Hmmm ...  CubeIDE seems to be incorrectly treating the "note" as an error.

Not quite sure what you mean by that?

You started out with v1.14.0 and then later updated to v1.17.0 ?

And you're still getting the error now that you're on v1.17.0 ?

Maybe something has been "inherited" from the older version?

What happens if you start from scratch with v1.17.0?
