It looks like you should be able to use nRF5 SDK v.10.0.0 with MDK-ARM 5.14 (keil)

I'm not saying it's impossible for you to use your nRF51, you'll just have to set up an environment to program it in.

You are basically telling me that what I intend to do is impossible to accomplish using this Board and toolchain Setup.

Is there some workaround using what I have before I get a new NRF52 ?

Can I set up some working environment and flash some custom project using the existing toolchain so i can work with the pins and control the lighting relays ?

Thanks

Right, the old SDKs won't work with the newest SES version, and SES wasn't supported as early as v.10.0.0.

Support for SES was added in nRF5 SDK v.14.1.0, you can see what IDEs and toolchains are supported for each version of the SDK in their release notes.

For example v.14.1.0 supports SES 3.30 and IAR 7.80.4.

So if you want to use v.10.0.0, you might have to use IAR 7.30.4.

You'll have to keep this in mind when choosing what version of the SDK to use.

Hi Einarh, these are the problems that I face during my first use of Segger according to the documentation that you sent me to follow.

I am using the latest SES version available for download.

I had no problems running the first test section but I need help starting with the section 7 of the document at the point of compiling the application code.

These are the differences that I noticed during the process.

1. First difference was that the crossed part was empty, and did not had any option to choose, but import went without errors.

2. this is how my build configuration looks like

3. I am using NRF SDK 10 because of the compatibility matrix that I followed for having all the functionalities for the NRF51 DK - pca10028 - so there was no (nRF5 SDK v12.x.x: flash_placement.xml)

4. Finally when i tried to build the solution it throws build errors as shown in the image

Please guide me through the process of compiling the project.

What am I missing ?

Hello

For the nRF51 I would recommend using the nRF5 SDK with SES. (For newer chips I would recommend nRF Connect SDK with VSCode but this does not support nRF51)

You should start by having a look at this guide:

Good luck!
