how to set the RAM start sddress of app and bootloader

[piepie]

I am working on OTA DFU about nRF52810. My refernece project are ble_app_uart\pca10040\s132 and bootloader_secure_ble\pca10040 I find that the RAM start address between are different. This is the start RAM address of APP:

This is the start RAM address of bootloader:

I am confusing why they are different? Is there anything I ignored? I am using SDK_14.0.0. How should I set the RAM start sddress of APP and bootloader? thx.

HI,piepie,

I'm doing something like you. But there is a place plagued me, nrf52810 the flash enough?

s132: 140kB

bootloader: 28KB (24KB dfu bootloader + 4kB bootloader setting)

ble_app_uart: 25KB

total:140+28+25 > 192KB

Do OTA also need double the app space, how do you solve this problem?

Hi Stayhungry, I thinke you can use S112 itstead of S132, which will save you quite much flash space. It is a alpha version for now and you can find it on the infocenter. Hope it helps :>
