Hi @alexmchp,

Thank you for your contribution. This FreeRTOS port falls into the category of "Partner Supported FreeRTOS Ports" as per the criteria recently published here. Accordingly, would you please move this port to the Partner Supported FreeRTOS Ports Repo. Similarly the FreeRTOS demo in this PR should be moved to Partner Supported FreeRTOS Demos Repo.

Let me know if you would like me to move these and I will be happy to do that.

Thanks.

Hi @aggarg, Thanks for the update. I will make sure future changes are done in the correct locations. It would be awesome if this time you could move them to the appropriate repos?

[alexmchp]

Hi @aggarg , any update on this ?

[aggarg]

Hi @alexmchp, Sorry it slipped my mind. Will look into it and update you.

[aggarg]

Hi @alexmchp, I moved the ports and opened this PR - FreeRTOS/FreeRTOS-Kernel-Partner-Supported-Ports#3

Please review and let me know if everything looks good.

[aggarg]

I am closing this PR as I have merged the above. Please let me know if anything looks off.

[alexmchp]

@aggarg thanks! awesome work!
what about this PR, can you move that too, or should we do it?

[aggarg]

@alexmchp - With this PR, I have removed these ports from the original location and added a README telling their new location.

Would you please move the demo projects to https://github.com/FreeRTOS/FreeRTOS-Partner-Supported-Demos? You will need to update source path and include paths for the port files.

Thanks.

@aggarg - I've created a new PR to https://github.com/FreeRTOS/FreeRTOS-Partner-Supported-Demos. The projects are now updated to new structure. Please let me know if anything else is needed
