Since i have 4 processes running on the uP so i want to schedule them in round robin fashion. Just wondering if any one can tell me how hard it is to do. I cannot use any other OS since this kernel is free and as document said very compa...

Hi, I'm trying to replace the box that does most of my basic network services, here: DNS, BOOTP, DHCP, Font server, NTP, TFTP, etc. All have reasonably light footprints (I think!). But, all have been written (NetBSD) assuming gobs of memory available! As the little box I am repurposing has a fixed (small) amount of RAM, I am nervous about building a "noswap" kernel -- the idea of ...

My project is to port uclinux on lpc2294. I've uClinux-dist-20070130 package downloaded from www.uclinux.org.

I'm not sure if i'm doing it right. Will someone guide me please??? Thanks in advance ...

I know it is not the best way to do but I've monitoring the MemFree value from /proc/meminfo and I'm losing 2M/hour. It's not that big but having 100M memory free makes it crash after two days.
