FreeBSD on the Neo1973 update

Andrew — Mon, 30 Jun 2008 09:38:46 +0000

I’ve just released a patch to FreeBSD 8-CURRENT to get it booting to single user mode on the Neo1973 emulator. I’ve written up some notes on using it the OpenMoko wiki. It’s best if you already know a bit about building FreeBSD as it can take some effort to build everything needed. However if you have an interest in testing it and giving me feedback I encourage you to give it a go.

In other news it appears I’m famous in Russia (Google translation)

The EFIKA is (kind of) booting

I managed to get my EFIKA to get to the point where it will complain there is no device to mount the root file system from. It is using a few dirty hacks and some code from NetBSD but these should be able to be removed when Peter Grehan has finished his changes to the openfirmware function.

I have made a tarball of the patches and extra files required here.

I’ve been working on getting FreeBSD booting on an EFIKA. I haven’t got it fully working but I can get it to the point when it will attempt to schedule tasks. It does show the state of the registers before the exception. I can use them to help figure out the state the CPU is in.

I’ve managed to track down the problem to calling the clock interrupt handler. It doesn’t appear to get to the code that handles the clock so I’m looking into where it its that it fails.
