Cannot open linker script file nrf_common.ld

[Tibor]

Hello,

we are using SEGGER Embedded Studio for ARM 4.16 to program Nordic chip nRF52832 (SDK is nRF5_SDK_15.3.0).
We would like to have some functions executed in RAM and wanted to use a manual linker script for this (as described in "SEGGER Linker, A linker for Cortex-M Microcontrollers, User Guide & Reference Manual").

We have activated the manual linker script within the linker options. Everytime we select a linker script (for ex. rtc_gcc_nrf52.ld in the rtc exemple case), following error message appears:
C:/Program Files/SEGGER/SEGGER Embedded Studio for ARM 4.16/gcc/arm-none-eabi/bin/ld: cannot open linker script file nrf_common.ld: No such file or directory
Build failed

Any idea why ?

Hi

It seems like you haven't added the nrf_common.ld file to your project. Please see this case for reference, as this guy is implementing something similar.

Best regards,

Simon

Hi Simon,

we were able to solve our issue via flash_placement file, using the .fast section instead of a linker script.

can you help me with this? How did you solved with flash_placement file?

[Tibor]

our goal was to put functions into RAM.

This can be done with __attribute__ ((section(".fast"))) void my_function(void) as the section fast is already configured in the flash_placement file.

My flash_placement.xml file looks like this. Where should I add this term to remove cannot open linker script file nrf_common.ld.

We were not able to open linker script file. We found a different way to place function into RAM without using linker script file.

[Meera Shah]

can you tell me how you have resolved? Or can you tell me how to resolve these errors.

 `.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

Does anyone resolved it ? I am facing the same issue after adding any section

Hi

This ticket is more than 3 years old at this point, and we've released multiple SDK versions (and versions of the SEGGER IDE has been released) since this with various bug fixes. I'd strongly recommend opening a new ticket explaining your issue in detail and add what SDK version etc. you're using for development.

Best regards,

Simon
