Embedded Studio With Bootloader + Application

Hi,

I know this is very late, but I struggled with this for quite a while. The solution I found to load the SoftDevice, Bootloader, and Application in Segger Embedded Studio with additional load files was to add the following lines to Segment Placement Macros in Edit Options->Linker

uicr_bootloader_start_address RX 0x10001014 0x4
bootloader_settings_page RX 0x0007F000 0x1000
mbr_params_page RX 0x0007E000 0x1000
uicr_mbr_params_page RX 0x10001018 0x4

And add the following XML sections to flash_placement.xml:

  <MemorySegment name="bootloader_settings_page" start="0x0007F000" size="0x1000">
    <ProgramSection alignment="4" keep="Yes" load="No" name=".bootloader_settings_page" address_symbol="__start_bootloader_settings_page" end_symbol="__stop_bootloader_settings_page" start = "0x0007F000" size="0x1000" />
  </MemorySegment>
  <MemorySegment name="mbr_params_page" start="0x0007E000" size="0x1000">
    <ProgramSection alignment="4" keep="Yes" load="No" name=".mbr_params_page" address_symbol="__start_mbr_params_page" end_symbol="__stop_mbr_params_page" start = "0x0007E000" size="0x1000" />
  </MemorySegment>
  <MemorySegment name="uicr_bootloader_start_address" start="0x10001014" size="0x4">
    <ProgramSection alignment="4" keep="Yes" load="Yes" name=".uicr_bootloader_start_address" address_symbol="__start_uicr_bootloader_start_address" end_symbol="__stop_uicr_bootloader_start_address" start = "0x10001014" size="0x4" />
  </MemorySegment>
  <MemorySegment name="uicr_mbr_params_page" start="0x10001018" size="0x4">
    <ProgramSection alignment="4" keep="Yes" load="Yes" name=".uicr_mbr_params_page" address_symbol="__start_uicr_mbr_params_page" end_symbol="__stop_uicr_mbr_params_page" start = "0x10001018" size="0x4" />
  </MemorySegment>

I think it was the issue of declaring the uicr_bootloader_start_address section in flash_placement.xml file Your main project file, the one that you use to combine other hex into (I assume it's the application ) should have this section defined, otherwise it's not possible for SES to integrate the bootloader and bootloader setting into the project.

I would assume you follow the sections definition in the flash_placement.xml in the bootloader project to add those sections into the application.

Thanks Hung Bui for the suggestion. I have edited the original question to include a screenshot of the error. I think I have the bootloader and main application overlapping since there respective Flash Section Placement files start at the same section. I'll need to edit them so they don't overlap. Each project works if it's the only one loaded.

Hi cwerther,

Could you take a screenshot of the error ? How did you configure the project that you use to flash ?

I assume you tested each project (application, bootloader) separately and they all works ?

Have you tried with only bootloader + application + softdevice and no "bootloader setting" file ?

I suspect the overlapping of flash section in the bootloader and bootloader setting caused the error.
