[ek-lm4f120-xl board can't be bought anymore, only its replacement TivaC can (and it is not supported by RIOT, at least at the moment)] It is actively maintained... sort of. I have the feeling that no RIOT developer has time for it. It is not listed on the RIOT wiki and it is hard to find

Hi, I'm all for cleaning up stale boards, especially I'd they are as hard to obtain as for example the FU boards. If I'm not mistaken this would also enable the removal of at least one legacy driver interface (I have some GPIO API in mind). Cheers, Ludwig Am 9. August 2016 13:52:56 MESZ,

Hi again. The point is that the VM hasn't got an OS. I mean that when I try to run the app on VM, the VM must not have Linux/MacOSX/Windows or whatever. The only thing that exists on the VM must be the RIOT app. From that point of view, yes, an OS must be running. P.S: Anyone who have

Hi, If you have been told to write an application that runs on a VM without using an OS, RIOT is not the answer because it is an OS, so your application is using an OS. Apart from that there is no difference between running on native and running on QEMU from the application point of view. As
