Trying to compile DFU bootloader code in segger embedded studio.

[Meera Shah]

When I tried to compile bootloader example code of sdk  bootloader_secure, I am facing some of the errors when I tried to compile using Segger Embedded Studio, which could not be solved. I think this is generating because of compiler difference. I am using s130.

`.bootloaderSettings' will not fit in region `UNPLACED_SECTIONS' region .

   In function `nrf_dfu_transports_init':
     undefined reference to `__stop_dfu_trans'
     undefined reference to `__start_dfu_trans'
   In function `nrf_dfu_bl_continue':
    undefined reference to `__isr_vector'
Build failed

Where does emWin come into this?

Can you build the unmodified example?

What SDK version are you using?

Are you using the provided SES Project file?

I am working with Segger Embedded Studio. I am using nRF5_SDK_12.3.0_d7731ad SDK. Yes I could build all the examples except this example nRF5_SDK_12.3.0_d7731ad\nRF5_SDK_12.3.0_d7731ad\examples\dfu\bootloader_secure . I ported this project from keil to Segger Embedded Studio.

Still no idea where emWin comes into this!

Aha! a key piece of information missing from the OP!

The message you got is from the Linker - so you haven't (quite) ported (all of) the linker configuration correctly.

So look carefully at the Keil linker configuration, and make sure you have that all correct in your SES Project.

It might help to look at a current SDK, as that will have an SES project - use that to guide you.

I checked all the linker configurations. Actually flash_placement.xml can resolve this , which I have seen from higher version SDK nRF5_SDK_15.0.0_a53641a(where ready SES project is there) but in this no Section placement File to add flash_placement.xml file.
