I read somewhere that eCos is API compatible with Linux so most Linux
software can be compiled and run on eCos. To what extent is this valid?
Thanks in advance.
I want to do some vision recogition experiments using an ordinary USB webcam
(640x480pixels should be more than sufficient) on eCos. Obviously, there are
no drivers for eCos so I'll have to write my own. Does anyone know if there
are USB webcams out there for which the transmitted USB packets are...
We are using ECOS for our embedded system. We currently use 250 threads
in the system. We would like to use more than 256, but we think 256 is the
maximum for ECOS. Is there any way to increase this to at least 1024?

Anybody have experience in implementing an eCos TCP/IP stack on an ARM?
Is a footprint of 200k program memory and 120k data memory reasonable?
Seems a little high to me. Without too much eCos experience, I might have
expected about half the program memory and 1/4 the data memory...
I am monica from germany. I have a newbie query.
what is the difference between eCos and redboot?
The documentation means redboot as a bootstrap environment.
But how can ecos run without redboot bootstrap?
Can anybody throw some light on the issue and give me some pointers
