STM32G030 write in flash but in different page position each time

Hi, erasing a complete page (2KB) to just write a few bytes is a waste of erase/write cycle. Is there a way to write data in differents part of the page each time? when there is no more space then a page erase should be fired and start over. Is there some implementation of it?

Thanks

Yes, this is called "EEPROM emulation". You may even find an application note on it and a complete software package - just search the ST website.
