Can't override a '__weak' function

[diverger]

Hi,

I write my own 'void HAL_SPI_TxRxCpltCallback(SPI_HandleTypeDef *hspi)', intend to override the default weak one. But when debug, my version is never called, it always steps into the 'weak' one. I'm new to CubeIDE, the version is 1.16.0, any suggestions?

Thanks.

Using .cpp ?

Double check spelling/capitalization

Perhaps use objdump to inspect generated object from your source file.

Hi,

My project is created as C++ project indeed. But my 'strong' version is defined in a ".c" file. Even I convert the project to 'C' project, my strong version won't be called. And I'm sure they have same signatures.

BTW: does CubeIDE support 'objdump'? I'm on Windows system, not Linux.

I'm running GNU/GCC on Windows and have objdump and objcopy, and on Keil I have fromelf

Not sure what CubeIDE brings in, but I'm not limited by that

Temporarily rename the weak one to something else, see if it compiles and links. Could be a misspelling in your strong version, or the string version isn't being compiled.
