RE: Bootloader code target size overwrites Pstorage allocation

You will likely have to allocate more flash if you are adding code to the example as it tight already. But note that in addition to adjusting the start address you will also need to change the UICR.BOOTLOADERADDR to reflect this new start address. E.g., dfu_types.h -> #define BOOTLOADER_REGION_START 0x3A0C0 (start should ideally be page aligned).

The error you saw should disappear if you subtract the size of the bootlaoder settings page from the allocated flash size:

0x40000 - 0x3A0C0 - 0x400 = 0x5B40 so IROM1 start: 0x3A0C0 size: 0x5B40.

Hi, there are two separate pstorage instances in the bootlaoder, one for the bootloader settings page @ 0x3FC00 and the other one for the banked region(s). Note that the bootlaoder uses Pstorage RAW.
