The EFIKA is an embedded PowerPC board with a 400MHz 32-bit freescale MPC5200 (603e/e300), 128MB RAM, 100MBit/s NIC, 2xUSB 1.1, Soundchip, 2.5" harddisk connector, PCI and AGP (with riser-card) and serial out.
Pylon received a board for development work on it. I will leave it in the C4, so that we can attach additional hardware on it.
Ideas for development tasks
- mpd-server as in-replacement for the already existing one
- connection to the Fnordlicht
- using jack for disco-lights
Booting
Harddisk
Currently I don't have any harddisk available, so this could not be tested. But it would be nice to create a complete stand-alone machine out of it.
USB
It's also possible to boot via USB. But it's only USB 1.1, so very slow.
NFS
I will use Gentoo/Linux on that machine. Yes, it might be slow, but it can be changed to your needs. Also it's possible to build on another PowerPC or with cross-dev.
Setup
- Server: 10.10.1.1
- Client: 10.10.1.2
Preparations
- Download a stage3-tar-ball and unpack it to e.g.
/nfsroot. - Change
/nfsroot//etc/fstab, so that the root-filesystem will be mounted via NFS:10.10.1.1:/nfsroot / nfs noatime 0 1 - Change
/nfsroot/etc/securettyand add a line for logging in later via serial-line:echo ttyPSC0 >> /nfsroot/etc/securetty - Also add that serial-line to
/nfsroot/etc/inittab:echo "s0:12345:respawn:/sbin/agetty 115200 ttyPSC0 vt100" >> /nfsroot/etc/inittab(you can use linux instead of vt100 for a coloured term, but then you should have a good serial communicotian program) - Add a password-hash for the root-password into
/nfsroot/etc/shadow. I used htpasswd2 from apache for it. Call it withhtpasswd -nb root secret. This will create the hash for the root-user with the password secret. Replace the*afterroot:in the shadow-file with that hash. - Give your system a hostname in
/nfsroot/etc/hostnameand add that hostname after the localhost-entry in/nfsroot/etc/hosts - Unfortunately mounting another nfs-share for the portage-tree later will not work, as nfs-utils are not installed yet (I'm working on a special nfsroot-efika-stage4). Bind-mounting a portage-tree on a Gentoo-system will not work either (nfs just ignores that). So we have to download and unpack a current portage-snapshot into
/nfsroot/usr/portage. Alternatively you can rsync your local portage-tree into/nfsroot:rsync --archive --progress --exclude=packages/ --exclude=distfiles/ /usr/portage/ /nfsroot/usr/portage/. - Finally unpack the precompiled modules into
/nfsroot(tar xvzf modules_efika.tgz -C /nfsroot/.
The nfsroot is now prepared for a first and simple boot. Let us now set up the dhcp-/tftp-/nfs-server-voodoo.
