STM32WB05KZ Build FLASH overflow

[Dadigno]

Hi Community,

I'm trying to build the BLE_TransparentMode example for the NUCLEO-WB05KZ, but I'm getting the following build error:

region 'FLASH' overflowed by 93348 bytes

 

Steps to reproduce:

• Open the BLE_TransparentMode example from the MX Example Selector for NUCLEO_WB05KZ.
• Change the toolchain to CMake with GCC compiler.
• Open the project and configure it using the STM32 VS Code extension.
• Build the project → the error appears.

Environment:

STM32CubeMX: v6.16

STM32CubeIDE for VS Code: v3.6.4

Has anyone encountered this issue or knows what might be causing the FLASH overflow with the CMake/GCC configuration?
Thanks!

Are you sure that the optimisation level is the same in  your modified project?

What happens if you build the example as-is - without any modifications ?

Hi,

build runs fine without any modifications, using stm32cubeide.

I think so, I didn’t change anything else except the compiler and toolchain settings from MX.

But have you checked?

Well, the optimisation level is a compiler setting!
