how to change CubeMX source files

Hello,

I created a small program with CubeMX to test STs USB device stack. My compiler (GCC) gave me a page full of warnings because of this declaration:

void USBD_GetString (uint8_t *desc, uint8_t *unicode, uint16_t *len);

When called a string is passed to desc, so its type is char* which causes a warning:

warning: pointer targets in passing argument 1 of 'USBD_GetString' differ in signedness [-Wpointer-sign]

If I change desc to char* it's fine

Now I want a solution that will keep this change when I create a new version via CubeMX, that means change the source file that CubeMX copies to my program. Where are these source files located on my computer? Any ideas?

Thanks

Martin.

Hi Mr_M_from_G,

Th source files used by CubeMx for each HAL library package are located under a repository in your hard drive. Try this one:

C:\Users\YourUserName\STM32Cube\Repository
