I cannot  write any data into the eeprom after a Erase_page.
HAL_FLASH_Program(..) and FLASH_Erase_Page(...) work fine independently. But if HAL_FLASH_Program(...) is called just after FLASH_Erase_Page(), HAL_FLASH_Program is not working. The data written are always 0x00.
Despite a 10 ms delay after the FLASH_Erase_Page, it is not working.
