CRUX PPC

Mount the CRUX PPC CD-ROM (or the CRUX PPC ISO image) to a directory of your server, e.g. to the directory /mnt/hd0. To export the above directory with NFS, put the following line into /etc/exports, and restart your NFS server. Be sure you have the required entry in /etc/hosts.allow too.

The Future

The Genesi EFIKA 5200B is a board based around the MPC5200B PowerPC® System-on-Chip from Freescale Semiconductor. A 32 Bit PowerPC with FPU, 603e processor core (e300) with access to 128MB DDR RAM (266MHz) of main memory. EFIKA provides small form factor design and high performance and integration, for multiple embedded, thin client, industrial applications, from a single board. \\

It's the easiest way but the slowest one caused by USB 1.1 data transfer rate. You can copy the content from the ISO to an USB pendrive already prepared with GNU Parted (remember msdos or amiga partition table and formatted as ext2 with 128-byte inodes).\\

There are several way to install CRUX PPC on this kind of machine and we'll reproduce three scenarios.

It's an easy way. If you have an adaptor you are able to install directly from CDROM otherwise you can install a basic system, from another PowerPC, into an 2.5" disk through USB cable and then move it on EFIKA. \\

It's the easiest way but the slowest one caused by USB1.1 Efika's ports. You can copy the content from the ISO to an USB pendrive already prepared with GNU Parted (remember msdos or amiga partition table and formatted as ext2 with 128-byte inodes).
Then you are able to start:

boot scsi:0 ppc/efika/zImage.chrp root=/dev/sdb1 rootdelay=10 panic=10 console=ttyPSC0

For further info please refer to CRUX PPC Handbook for a regular installation.

If all the procedure goes well, you should see on your own serial terminal the following.

You need a PowerPC machine to native compile it or a working cross toolchain.
All our kernels include NFS client support therefore you can skip this section.\\

HOWTO install GNU/Linux CRUX PPC on Genesi EFIKA

The EFIKA 5200B is a board based around the MPC5200B PowerPC® System-on-Chip from Freescale Semiconductor. EFIKA provides small form factor design and high performance and integration, for multiple embedded, thin client, industrial applications, from a single board.
There are several way to install CRUX PPC on this kind of machine and we'll reproduce a couple of scenarios.

We, now, describe the installation of CRUX PPC 2.2 from a NFS server of your local network. This may be useful if you have a running CRUX box and you cannot install CRUX PPC on your other computer via CD-ROM, or, more conceivable, because EFIKA doesn't have any CD-ROM drive.

or eventually any other MPC5k2 SoC

The EFIKA 5200B is a performance evaluation board based around the MPC5200B PowerPC® System-on-Chip from Freescale Semiconductor. \\

The kernel has been tuned for MPC5K2 based boards, not only EFIKA, so CRUX PPC will, presumably, support many of them, with similar install procedures.

It's the easy way. You can install a basic system, from another PowerPC, into an 2.5" disk through USB cable and then move it on EFIKA.

Hard Drive install from CDROM

It's the easy way. You can install a basic system, from another PowerPC, into an 2.5" disk through USB cable and then move it on EFIKA.
For further info please refer to CRUX PPC Handbook for a regular installation.

Install CRUX PPC via NFS

We, now, describe the installation of CRUX PPC from a NFS server of your local network. This may be useful if you have a running CRUX box and you cannot install CRUX PPC on your other computer via CD-ROM, or, more conceivable, because EFIKA hasn't any CD-ROM drive.

1. prepare your server

Mount the CRUX PPC CD-ROM (or the CRUX PPC ISO image) to a directory of your server, e.g. to the directory /mnt/hd0. To export the above directory with NFS, put the following line into /etc/exports, and restart your NFS server. Be sure you have the required entry in /etc/hosts.allow too.

/mnt/hd0 *(ro,no_root_squash,sync,no_subtree_check)
and remember to start the NFS Server

1. /etc/rc.d/nfsserver start
   

2. create your bootkernel

All our kernels include NFS client support therefore you can skip this section.
Make a backup of your current kernel configuration:

1. cp /usr/src/linux/.config /usr/src/linux/.config.save
   

Get the configuration file for the CRUX PPC bootkernel from the ISO. This file is always named like linux-2.6.20.config and copy it into your kernel source tree:

1. cp linux-2.6.10.config /usr/src/linux-2.6.10/.config
   

Goto /usr/src/linux-2.6.20, run make menuconfig and add to the configuration:

• Networking
  • Networking support
    • Networking options
      • Unix domain sockets
      • TCP/IP networking
      • IP: kernel level autoconfiguration
      • IP: DHCP support
      • IP: BOOTP support
      • IP: RARP support
• Device Drivers
  • Network device support
    • add your network interface card(s)
• File systems
  • Pseudo filesystems
    • /proc file system support
    • sysfs file system support
    • Virtual memory file system support (former shm fs)
  • Network File Systems
    • NFS file system support
    • Provide NFSv3 client support
    • Root file system on NFS

Don't use modules, all options must be compiled into the kernel. Build the kernel as usual and only enable stuff you really need.

3. locate your bootkernel

You can, simply, copy the EFIKA tuned kernel image from our ISO on a USB pendrive and use it to boot or you can set up an ad hoc TFTP server so that the EFIKA can fetch it over the network.

4. booting

When you power up the EFIKA, you should get the OF (OpenFirmware) prompt:

In this scenario we have a 2.5" 4.8GB hard disk drive and a 256MB USB pendrive attached on the EFIKA. Here you can see the situation from the OF prompt:

5. NFS installation procedure

Let's go to prepare the board for netbooting. It's possible to set the EFIKA's ip for TFTP and the TFTP server's ip address in NVRAM (instead of specifying them in the boot command), for further info about this OF release please refer to Genesi EFIKA HowTo Guide. Here just an example:

ok setenv server-ip 192.168.0.11

server-ip = 192.168.0.11

ok setenv client-ip 192.168.0.27

client-ip = 192.168.0.27

But we have choose to fetch the kernel and start the boot process, simply, from our USB pendrive then:

ok boot hd0:0 zImage-Efika nfsaddrs=cip:sip:gip:netm nfsroot=/mnt/hd0 console=ttyPSC0 panic=10

replacing in nfsaddres argument with:

• sip: ip address of your server (e.g. 192.168.0.11)
• cip: ip address of your client (e.g. 192.168.0.27)
• gip: ip address of your gateway (e.g. _blank_) (optionally)
• netm: your netmask (e.g. 255.255.255.0)

we now have:

ok boot hd0:0 zImage-Efika nfsaddrs=192.168.0.27:192.168.0.11::255.255.255.0 nfsroot=/mnt/hd0 console=ttyPSC0 panic=10

If all the procedure goes well, you should see the following.

The Future

In the near future we'll release a starter kit and we're considering two options and probably we'll produce both..
A first solution is a very trimmed system in a tar file, so it's ready to be untarred on an usb pendrive and then configured and used, or used for a more complete install on some other media. The second one is a live CD for PPC and a live CD for x86 with TFTP server and NFS share ready, so the EFIKA can boot the installer from network.
