Hi,i have some problems when develop with experimental_ble_app_buttonless_dfu project in sdk12.3 on IDE embedded studio (MAC OS). I follow thislink text to develop.when build,it show me that Output/nrf51422_xxac/Exe/ble_app_buttonless_dfu_pca10028_s130.elf section 'bootloader_Settings'will not fit in region'UNPLACED_SECTIONS'. I do not how to deal with this error. When I develop with ble_app_hrs project in sdk12.3, it works well.

Hi aliveziaoluo,

You would need to declare the memory segment for the bootloaderSettings. It's similar to how we declare the bootloader_settings_page in SDK v14.1

I would suggest you to follow what we have in the SES bootloader project in SDK v14.1 to build your bootloader project in SDK v12.3

I follow your suggestion and replace the flash_placement.xml in experimental_ble_app_buttonless_dfu project in sdk12.3 with the flash_placement.xml in ble_app_buttonless_dfu project in sdk14.1.After solve some build errors,build ,it shows me nrf51422_xxac/Obj/ble_app_buttonless_dfu_pca10028_s130.ld:27 syntax error.

I find this,by add <ProgramSection alignment="4" load="Yes" name=".bootloaderSettings" start="$(BOOTLOADER_SETTINGS_START:0x0003FC00)" size="$(BOOTLOADER_SETTINGS_SIZE:0x400)" /> in flash_placement.xml(the project auto generate). errors solved and project work well.

But there is other things i want to ask for help.my app project use experimental_ble_app_buttonless_dfu and works well after above.my bootloader project use bootloader_secure project,then build,it show me some errors in flash_placement.xml.i do not know how to deal with errors. The flash_placemnet.xml file auto generate.i do not how to generate flash_placemnet.xml in different project.I will post the error in next comment.(The app and bootloader project work well in keil windows)
