I'm looking forward to learning more about eCos. Unfortunately, this is a "skunkworks" project, and I am looking into it on my own time, so progress may be (relatively) slow. The local gurus decided about 1 yr ago to embed Linux, and now we are having lots of problems related to non-deterministic scheduling latencies, lack of priority inheritance, code size, ram requirements, etc. I told 'em at the time these would be problems, but they charged ahead, anyway. :-( I was new to the company - but not embedded real-time systems (14 years) - and it was easy to ignore me. ;-( Rather than believe me that there is a difference between "real-fast" and "real-time", they are learning on their own, the hard way. This year, they want to integrate some closed-loop control that is currently on a separate micro-controller. So, I'll get to teach them about the problems with non-deterministic interrupt latencies, too. Oh joy ... I'm hoping the EL/IX Linux API might be a face-saving stepping stone for the powers that be, which will allow us to swap out Linux for eCos. I have no permission or allocated time to look into this, but I'm pretty sure that's what needs to be done. All in a days work. Thanks again for your help!
