nRF51422 Segger ES 4.30b example

[Ros]

Hi,

I converted ble_app_beacon example to Segger Embedded Studio (using version 4.30b), as per the instructions in the link https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_gsg_ses%2FUG%2Fgsg%2Fimport_ses.html and the project file is given blow:

Every step was successful except the last two ("Right-click on your project in the Project Explorer and select Import Section Placement.") because I didn't get that option even though I changed the linker option to GNU (And also tried arm_linker_variant="GNU").

When compiled, I received lots or linker errors as shown below (I also tried after adding flash_placement.xml in the project file replacing the link_linker_script_file="$(StudioDir)/samples/SEGGER_Flash.icf".

Is there any working project file with necessary startup files for SES version 4.30b? Or nrf51422 is no longer in production?

Hi

I forgot to touch upon this in my initial reply, but the nRF51422 is definitely still in production, we just don't have support for it beyond SDK v.12.3. I think the example in Vidar's reply should work as long as you follow the instructions he added and use SES v.4.12 or similar. Is there a particular reason you need to use v.4.30b?

I have requested for the blog post to be updated, but I can't guarantee that this will be prioritized any time soon.

Best regards,

Simon

I have solved the issue, the main reason was the linker placement segments are named differently in project file (created by converting Keil project) and flash_placement.xml file.

linker_section_placements_segments="FLASH RX 0x00000000 0x00040000;RAM RWX 0x20000000 0x00008000"

and also changed the start up files.

<folder Name="Segger Startup Files">
      <file file_name="$(StudioDir)/source/thumb_crt0.s" />
</folder>
<folder Name="None">
  <file file_name="../../../../../../components/toolchain/ses/ses_startup_nrf_common.s" />
  <file file_name="../../../../../../components/toolchain/system_nrf51.c" />
  <file file_name="../../../../../../components/toolchain/ses/ses_startup_nrf51.s" />
</folder>
