Using qemu-user to chroot and bootstrap other architectures on #FreeBSD
My last post spawned enough feedback that I thought I would dump some notes here for those interested in building a chroot on FreeBSD that allows you to test and prototype architectures, e.g. ARMv6 on AMD64. The FreeBSD buildsys has many targets used for many things, the two we care about here are buildworld and […]

Sometimes you have to sit down and write #FreeBSD documentation
When working on new projects or hacks, sometimes you just have to stop, think and start writing down your processes and discoveries. While working on bootstrapping the DLink DIR-825C1, I realized that I had accumulated a lot of new (to me) knowledge from the FreeBSD Community (namely, Adrian Chadd and Warner Losh). There is a […]

How to fry a router in X-1 steps, The Serial Console complete

How to fry a router, in X easy steps: The Serial Console
I’ve started to hack on my DLink DIR-825 B1 to get it running FreeBSD and have had some great success. Adrian Chadd, adrian@freebsd.org put together a build system for this router and committed some of the needed changes to get this Atheros MIPS 24k based router working for us and I’ll try to document my […]

The sacrifices we must make for science!
Interesting day on the phone with DLink. When I say “day”, I do mean DAY. More or less, Monday must be DLink’s crazy time when everyone comes back from work and finds their office routers dead or something. The DIR-825 model C1 that I initially bought to test out MIPS on FreeBSD died a noble […]
