Hi, good morning, I have a compilation error what I add Flash functions such as HAL_FLASH_Unloc() ... I don't understand why, maybe I miss a setting in the project. The microcontroller is ESP32G070xx. Can anyone help me? Thank you very much Julian

#include "stm32g0xx_hal.h"

  HAL_FLASH_Unlock();

  FLASH_Erase_Sector( FLASH_SECTOR_11,VOLTAGE_RANGE_1 );

  HAL_FLASH_Lock();

Hello @JMigl.1​ ,

Let me first welcome you to the STM32 Community =)

Regarding your reported issue, I think you should check the contents of the header files and your declarations.

I advise you to refer to the STM32CubeG0 MCU package and look at the source files to see how to use them.

You can start from a working example to have more idea about implementation, initialization code and related functions. Then make required updates according to your needs.
