Error in build about MX_Init gpio and icache

[hela]

Hello!

When I build my project, I get these errors. I should note that the header files are in the driver folder, and I have added all the necessary include paths.

"C:/Users/helat/STM32CubeIDE/workspace_1.18.1/PFA-SecureM/Core/Src/main.c:90:(.text.main+0xc): undefined reference to `MX_GPIO_Init'

those are linker errors. check the source folders/files that will be linked. C++ issues?

This means that MX_ICACHE_Init has been used prior to its definition. Ensure it is being defined before used.

If this code is directly generated from an IOC, please include that IOC. Otherwise please include your project code files.
