How to create a custom library hex, similar to soft device, that can be used by another firmware?

[arshi]

I have a custom firmware that I want to turn it into a library, whose APIs can be used with any firmware and will be flashed along with it, similar to how Nordic's softdevices are flashed and can be used. Is there any way that I can achieve this? Any help will be greatly appreciated.

Hi,

 

You could look at this project on how to create a static library file:

Kind regars,

Hii, could you share how it can be done in Segger Embedded studio?

Hi,

 

My apologies, you're using nrf5 sdk.

Here's a way to setup a project for this: https://wiki.segger.com/How_to_create_a_library_project_and_use_it_in_executable_project

 

Kind regards,

Instead of creating a library project, I want to link an precompiled .hex file and its associated map file to an executable project and make API calls to the api's defined in the provided hex file

We do not have any pre-made project for this. This is something you have to define yourself.

 

Kind regards,

Håkon

That's okay. I just wanted to know how it can be done in segger. What steps or configurations do i need to change to add the external .hex as a dependency.

Hi,

 

To automatically load another .hex file in SES, you can point to it in the "additional load file" section, like we do here in BLE based projects:

 

Kind regards,
