I am trying to program STM32F042K6 nucleo using CubeIDE and STM32 HAL but the compiler throws an error:
region `FLASH' overflowed by 1212 bytes.
Here is the exact console output:
09:55:03 **** Incremental Build of configuration Debug for project Virtual Com Port ****

09:55:04 Build Failed. 3 errors, 0 warnings. (took 340ms).
However, when I look at the memory regions in the build analyzer, it shows 16.58 KB free out of 32KB size for a usage of 48.19%. If only 48% of the flash storage is used, then how is the flash overflowing by 1212 bytes and what can I do to fix this?
