Unable to build secure bootloader ble s132 on SDK 15.3

StephaneJ

Hi,

I have updated our SDK version from 15.0.0 to 15.3.0 for our custom board based on nrf52832 

I wanted to rebuild the bootloader just in case it was needed. So i have opened the solution from examples/dfu/secure_bootloader/pca10040_ble/ses using SeS version 5.42a

But when I built it I got an error message saying

section .uicr_bootloader_start_address VMA [0000000000000ff8,0000000000000ffb] overlaps section .reserved_flash VMA [0000000000000000,0000000000077fff]

I have tried the solution suggested here : https://devzone.nordicsemi.com/f/nordic-q-a/47651/uicr_mbr_params_page-and-uicr_bootloader_start_address-overwrite-the-beginning-of-the-softdevice

By updating the flash placement from :

<MemorySegment name="uicr_bootloader_start_address" start="0x00000FF8" 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 = "0x00000FF8" size="0x4" />
</MemorySegment>
<MemorySegment name="uicr_mbr_params_page" start="0x00000FFC" 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 = "0x00000FFC" size="0x4" />
</MemorySegment>

To this :

<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>
<MemorySegment name="uicr_bootloader_start_address" start="0x10001014" size="0x04">
  <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="0x04" />
</MemorySegment>

With that changes, the built succeed but I'm not sure the flash placement parameters are good for my config since the original post is for nRF52840 and not for a nRF52832.

Thanks
