Misaligned memory write causes hard fault.

Hi,I checked with the test code below, and it sets the hard fault for the G0 controller. It looks like an alignment issue. But the same code runs fine with L4 and F4 microcontrollers and does not set any fault for misaligned assignments. Project sett...

When using FreeRTOS, CubeIDE generates a file, system_stm32f7xx.c under Drivers/CMSIS/Device/ST/STM32Fxx/Source/Templates. This happens regardless of the version of the interface (V1 or V2), in 1.6.0, for at least the F767 processor. Is this a bug?

The file contains duplicate definitions, seems to have no purpose, and prevents compilation unless deleted. This is a C++ project.Given the source code (which I wouldn't have), I'd look at the specific reason that the template file is included. It ...

STM32CubeIDE: when I "convert to C++" a C project the only difference seems to be that .cpp source files are also compiled during build while in a C project they are not. Is my understanding correct?

Resolved! The selection couldn't not be launched.

I used this: File --> New --> STM32 Project --> example selector in STM32CubeIDE, the project could be saw in IDE: but the build icon was unable, when I clicked "run", it was prompted:
