Hi Adriana!
If you take a look at the video tutorial series i linked to in my answer, specially the last video;
SEGGER Embedded Studio - Basics of debugging
At around 4 minutes, I explain how to change the RAM start and size in SES.
Best regards.

Hi! I am also using Segger Embedded Studio V3.30 IDE and nrf SDK version 14.1 but with Window 8.1 Pro. I have successfully build and debug some projects from the SDK. But now I want to adjust RAM sections and don't know how to do it from the IDE.

I have tried to use the linker script provided by the SDK for gcc instead of the automatically generated by SES but I don't think this is a good idea. Wich is the proper way to adjust RAM start and size from the IDE?

Great news! Tested it and everything really worked without additional configuration. Thank you.

Hi Ricards!

It's not necessary to follow that blog-post to use SEGGER Embedded Studio with SDK v14.1.
There is already added ready-to-use SEGGER Embedded Studio projects in the SDK.
For the hrs example, go to the folder:
<SDK_Installfolder>\examples\ble_peripheral\ble_app_hrs\pca10040\s132\ses
and open the SES project.

You can watch this video tutorial series on youtube, on how to use the SDK with SES.

Let me know if you face any problems!
Best regards,
Joakim.
