STM32H563 OEMiROT Non-Secure Application flash size

Hello,

starting from the example application of the OEMiRot boot project, I noticed that the NS application size is limited to 640kB in the flash_layout.h  (#define FLASH_NS_PARTITION_SIZE (0xA0000) /* 640 KB for NS partition */)

Since there is 1MB avalaible in the slot, I would like to increase this size from 640kB to 896kB. A first naive change is just to change the define from 0xA0000 to 0xE0000 which leads to the state that the bootloader doesn't find a bootable image anymore.
How do I set a larger non-secure application size to have a benefit of the 1MB flash slot?

 

Best regards,
Stefan
