Linker giving error when building the ble_app_alert_notification_pca10028_s130

Hi

Why exactly are you changing stuff in the flash placement file? Is there a reason you set the RAM name to RAM1? This is only necessary when updating to SDK v17.0.2, so please revert this change. This likely causes a conflict with where where the RAM name "RAM" is used define the RAM segments, which is why you're getting this new error.

Next for your actual issue, I think that is due to missing a step somewhere in the SES import guide https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/segger-embedded-studio-a-cross-platform-ide. Can you double check that you for example have done the Adding nRF5 MDK files section correctly? 

• Download ses_nrf51_startup.s and save it into NRF5_SDK/components/toolchain/embedded_studio/ (create the folder)
• Remove Cortex_M_Startup.s from the Internal Files folder in the Project Explorer
• Right click the Internal Files folder and select Add Existing File...
• In NRF5_SDK/components/toolchain/ select system_nrf51.c
• Do the same for NRF5_SDK/components/toolchain/embedded_studio/ses_nrf51_startup.s
• Select Project -> Edit Options... and then select the Preprocessor tab
• Add ../../../../../../components/device to the User Include Directories field to include the device header files in our Embedded Studio project

Hi Simon,

Actually I was able to completely build the project by changing the "__RAM_segment_end__" reference to "__RAM1_segment_end__". Hope that is fine.

However, When I tried the s130 softdevice 2.0.1 with the peripheral example in the 12.3.0 SDK, the soft device initialization returns error code 8. 

My device kit is an nrf51422 device. From the compatibility matrix I read that for nrf51422, the peripheral examples are compatible with S110 softdevice and the (central and peripheral) examples are compatible with S130.

Is that true?

So for trying out a peripheral example in the 12.3.0 SDK, I would need S110?

Thanks.

best regards,

Rajkumar

Hi Simon,

I did as you suggested(importing a project) from scratch. I imported a new project(ble_app_proximity). I did all the import steps you mentioned and did a compile.

I am now getting some linker errors. Please see attached file.

I am using Nordic Segger Embedded studio version 5.68 from the following site: 

https://www.nordicsemi.com/Products/Development-tools/Segger-Embedded-Studio/Download?lang=en as suggested by my team member.

Please let me know what I should do.

Hi again Rajkumar

Okay, if your flash_placement file is now set up correctly, you also need to set up RAM and Flash memory segments in your project settings as explained in this blog post. Remember to select the Common configuration in the project options window.

Best regards,

Simon

Hi Simon,

I made the changes to the Section placement macros as shown in attached file. I also made changes to the memory segment macros as attached in the 2nd file.

However, when I flash the 2.0.1 Softdevice hex file(using Nrfgo studio) and then use "Debug" menu option in EMbedded studio to run the application(app_ble_ancs_c),

1. First time I run the debugger after flashing the soft device, the program stops and main and then after a few functions, the ble_stack_init runs through successfully but then fails either at peer_manager_init() or later.

2. The 2nd time and  after that, when I run the debugger after flashing the softdeviec code and running the debugger, the function ble_stack_init() always gives error code 8 at the app_error.c.

I have not been able to see the bluetooth device using my phone bluetooth scanning even once.

The failure seems to happen at sd_softdevice_enable() which causes the fault.

The clock use is the external crystal. There is no change made to the example code.

Please let me know where I could be going wrong.
