Another such light-weight embedded C kernel with unmapped ARM support
that seems to be popular lately is microC/OS, sometimes called
uC/OS or "mucos". My _impression_ is that it is a free open source system
but that a number of companies sell support and a number of embedded
companies specialize in getting it past validation suites in vertical
niche markets, etc.. I think it's been used for digital cameras and such.
