Hi


Usually for address starting from 0x10, it is allocated for the factory image.

If you set the RU_CONFIGURATION_MODE to boot from factory image it will load the factory image if not it will load from the other application start address.


If you want to update the flash image, you could write directly to the address image address.

The RU_PAGE_SELECT register is the address in which the RSU will boot from.


After you write the image directly to the address. Then you update the RU_PAGE_SELECT with the start address you written to. Lastly you can trigger a reconfiguration by writing to the RU_RECONFIG.
