FUOTA possibility of update

Hi,
I am working on a firmware update over the air project on STM32L0 discovery board and I was wonder if it is possible to just send an update for specific part like application, or only update HAL instead of full image.
could you please tell me if it is possible?
thank you,

Hi,

I’m also working on a FUOTA project and the only thing you can’t update is the bootloader.
For the update you can either update the full image or do a delta update which compare the the actual firmware and the new one and then send only the difference
