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

Best regards,

Simon

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.

regards,

Rajkumar
