Nano on a Raspberry Pi Pico

Indeed and I mentioned in my question that I can follow this tutorial to build a standard project.
when I select Nano project instead of Standard project I find that there is no BSP for the Pico and I cannot find how to add one.
so, the question is: can the IDE build a project based on the Nano kernel and if so, how?
I have been working with FreeRTOS but the core size is much bigger than the small size discussed for the RT-Thread Nano kernel.
Maybe I just have to take the Nano kernel source and integrate it with the Pico SDK outside the Eclipse-based IDE.
I do admit to a preference to a command line build that would allow me do do all my development in the Linux environment.
the RT-Thread Nano kernel looks really nice, it just doesn’t run out-of-the-box.
