| + | ====== NetBSD on the DNS-323 ====== | ||
| + | |||
| + | ===== Introduction ===== | ||
| + | The usual disclaimer applies. If you brick your device it is your fault 100% of the time. This page describes what has always worked for my DNS 323 hardware. | ||
| + | |||
| + | NetBSD was ported by Kiyohara in 2007 but is not yet part of the official tree so you have to get current and patch it. The patches are in http://ftp.netbsd.org/pub/NetBSD/misc/kiyohara/orion_nas. | ||
| + | |||
| + | The entire NetBSD distribution can be built using a Linux box so there is no need to switch from your favourite OS. The build.sh script that comes with the NetBSD sources builds everything or just the cross-compiler or just the kernel depending on the arguments passed to it. | ||
| + | |||
| + | I will focus on building the kernel and the cross compiler for now. Once the kernel is built you could save time by downloading userland from the netbsd.org because all little-endian arm boards share the same binaries. The final result is going to be a standard NetBSD installation (like the one on a PC) except that this one runs on ARM. That is how my setup is but you can do whatever you want obviously. | ||
