i did increase the CONFIG_PM_PARTITION_SIZE_MCUBOOT to 0x10000, but whenever i try to build it revert back to 0xc000 for some reason

This is the config file i used

Hi,

Seems you get a "FLASH overflowed" error from mcuboot, you can try to increase CONFIG_PM_PARTITION_SIZE_MCUBOOT to 0x10000 as explained in Device Firmware Update (DFU) with MCUBoot bootloader. Check the file <application>/<build>/mcuboot/zephyr/.config and confirm that CONFIG_PM_PARTITION_SIZE_MCUBOOT got the correct value.

Regards,
Amanda
