Error Migrating Secure Bootloader Project from Keil to Segger Embedded Studio

[KrishNa]

Hello NRF Buddies,

My project is based on NRF51822 with SDK version 12.2.0. I am working with Keil till now and planning to migrate to the Segger Embedded Studio.

With the help of the nordic support team, i was able to successfully compile and run the application project on to my custom board. But when i tried migrating the bootloader project from keil to Segger Embedded Studio the same way, i am getting compilation errors.

Attaching the screenshot of the error for your reference.

Awaiting your response.

Hello,

Can you upload the bootloader project here so I can take a look? The build log does not provide much information about what's causing the problem.

Best regards,

There is a formatting issue with one of your preprocessor symbols (should have been NRF_LOG_BACKEND_USES_RTT=1 on one line):

 

 Fixing this should solve the build error you reported. But there are still some linker errors that need to be solved. Try to use this flash_placement.xml:
