I am an embedded system engineer, I use ARM920T and linux in my projects. I am familiar with ARM architecture and linux device driver. Now I intend to study the principle of OS, but I find the linux kernel is too large and complex, so I change to FreeBSD. Would the FreeBSD-ARM be very complex? How many lines would the source code of the kernel (without device drivers, just the key modules like FS, MM, porcess scheduler, TCP/IP and the others) be? I hope I could make some contribution to FreeBSD-ARM, to compete with other OS like linux and vxWork (they are used widely in PR.China). It is nice of you to reply me. I would be admiring to receive your reply. Thank you.
