USB HID device on STM32F042F4 using CubeMX - FLASH overflow.

Hi,

When I set the USB class to anything in CubeMX, the compiler gives me the error - FLASH overflow. It happens even with a completely empty main.c file, so is there a way to make it work, or should I choose MCU with 32kB flash (it will fit then)? The current one has 16kB.

You can try turning on optimization to see if it reduces the code size enough. Change the build configuration to Release.

Project -> Build Configurations -> Set Active -> Release

Generally, CubeMX and HAL wasn't created for chips with small FLASH sizes.
