How much time did you actually spend researching the subject before posting your questions on the mailing list? If you had your homework, you would have found out that eCos is very much alive, and that snapshots of the latest development tree are issued every week, not every month or every year. If you had spent more than a passing moment on the web site of the fine people at eCosCentric you would have found that under the "DevZone" tab there is menu called Snapshots. Do you care to guess where that leads you? And if you had spent more than a passing moment actually _reading_ the mailing lists you would have found that people keep posting patches almost every day, not only making old packages even better, but also adding new ones. > 2) eCOS doesn't distinguish between privilege levels.

That assumes that you have full support for an MMU. Ecos' use of MMU is limited to static configuration of MMUs, even in those architectures that actually have an MMU built in. Don't blame eCos for missing MMU support: This is a carefully thought decision on the part of the eCos architects. Remember that we are talking about real time systems, where dynamic manipulation of an MMU is not such a great idea. If you need a full MMU, Linux is your OS.
