I think the NuttX focus should be MCUs with realtime requirements (something with Linux cannot offer). In the other hand many companies want NuttX to be a replacement to Linux itself. I think both goals don't need to be conflicting. But we cannot lose the main focus just to be more Linux-like. > > @hujun260 @anchao @xiaoxiang781216 how to fix this conflict in a way both goals could be meet? > > Nobody want to change NuttX to Linux, but the big critical section need be addressed since: > > 1.
