i'm using stm32c011f4u6 mcu's DK(stm32c0116dk), and i generate the file as mdk-arm and it's running with keil5.
i tried erase to test the flash memory, but it doesn't work. i even used the SDK example file, and i get the same error.
Below is the main.c file.

An error occurs in the function including breakpoint in the picture above. if i run the program, i'll be stuck in that infinite loop.
Why is this problem happening?

Hi @KenLee ,
Thank you for updating post.
I think that the problem is more likely related to the software environment or configuration on the specific PC rather than the hardware, because the issue is not consistent across all PCs and all toolchain like STM32CubeIDE.
I suggest you to compare the configurations and software versions between the PCs to identify any discrepancies.
Could you please try to reinstall keil and to use FLASH_EraseProgram example of STM32CubeC0 V1.1.0.
Note that, this example is developed with MDK-ARM toolchain V5.36 as mentioned in the release note.
Thank you.
