= Avila board development [ Avila GW2348-4 Intel XScale IXP425] =
The intention of this exercise is to get the board to run Linux. There are number of ways to do this and will consider as many as feasible.
== Running OpenWRT on Avila board ==
The following steps were performed to get the board to run OpenWRT
===Requirements===
A. Installing and setting up tftp server (Ubuntu, hardy)


B. Download two files 'openwrt-ixp4xx-squashfs.img' and 'openwrt-ixp4xx-zImage'
migrated to wireless dev
 
C. Upload OpenWRT onto the board
==== A. Installing and setting up tftp server (Ubuntu, hardy)====
The diagram below shows the setup we will be using to setup and test the tftp server. The tftp server machine, sun, will be given IP address 192.168.3.1 and the client machine, moon, will be given IP address 192.168.3.2.

miguel@sun:~ sudo apt-get install xinetd tftpd tftp
miguel@sun:~ vi /etc/xinetd.d/tftp
;Add the following lines in /etc/xinetd.d/tftp
service tftp
{
protocol        = udp
port            = 69
socket_type    = dgram
wait            = yes
user            = nobody              //Please note if you have trouble with running tftpd, change "nobody" to "root"
server          = /usr/sbin/in.tftpd
server_args    = /tftpboot
disable        = no
}
;Create /tftpboot directory
miguel@sun:~ sudo mkdir /tftpboot
miguel@sun:~ sudo chmod -R 777 /tftpboot //Please note the permissions need not be 777 but should be at least 444 (i.e readable by all)
miguel@sun:~ sudo chown -R nobody /tftpboot //Please change "nobody" to "root" if in file /etc/xinetd.d/tftp you have specified "root"
 
;Start tftpd using xinetd
 
miguel@sun:~ sudo /etc/init.d/xinetd start
 
;Testing tftp server
We test tftp server by transfering a file from a client called 'moon' with IP address 192.168.3.2) to tftp server called 'sun' with IP address 192.168.3.1. Assuming you have file testTFTP.txt in your home directory on the client machine:
miguel@moon:~ ls -l testTFTP.txt
-rw-r--r-- 1 miguel miguel  3551088 2008-04-19 15:52 testTFTP.txt
miguel@moon:~ tftp 192.168.3.1
miguel@moon:~ trace
miguel@moon:~ put testTFTP.txt

Now logon to the 'sun' machine (the tftp server) and run 'ls' and your uploaded file should be there(hopefully).
miguel@sun:~ ls - -l /tftpboot/

;We now have a working tftp server!!
 
====  B. '''Download'''  two files, '''openwrt-ixp4xx-squashfs.img''' and '''openwrt-ixp4xx-zImage''' on to tftp server====
 
Visit http://ftp.iasi.roedu.net/mirrors/openwrt.org/snapshots/ixp4xx/ and download files ''openwrt-ixp4xx-squashfs.img'' and ''openwrt-ixp4xx-zImage'' and save these files to /tftpboot directory of the tftp server. Make sure the files are readable
miguel@sun:~ ls - -l /tftpboot/

Select the letters A-G to change the settings and press the "enter" key to get out of the menu back to the main menu. The final settings should be as shown above.
 
Connect the Avila board to your PC/laptop using a serial cable. Power-up the Avila and repeatedly press Ctrl+C until the board displays Redboot. This is what I see on my board:

As shown, my board has the follwoing IP settings:
 
Local IP address: 192.168.3.2
Local IP address mask: 255.255.255.0
Default server IP address: 192.168.3.1
 
If after pressing Ctrl+C your board didn't not display the same information as above, then to see your IP settings do this
RedBoot> ip_address
IP: 192.168.3.2/255.255.255.0, Gateway: 0.0.0.0
Default server: 192.168.3.1
Use the "ip_address" command to change the IP settings if you need to. Remember in our case we have the tftp server set to 192.168.3.1 so the line "Default server: 192.168.3.1" above is correct. Change yours if it's not correct.
 
 
Now we need to initialize the FLASH
RedBoot>fis init
Answer yes by typing Y or y to the question below
About to initialize [format] FLASH image system - continue (y/n)?
You should see the following output:
*** Initialize FLASH Image System

RedBoot>
Next we check to see free available space
RedBoot> fis free
  0x50080000 .. 0x50FE0000
Therefore we have 0x00f60000 (16MB) available space
We now copy the linux file from the ftp server as raw data (option -r) to memory address 0x0080000 (option -b) and want a progress indicator (option -v).
RedBoot> load -r -v -b 0x00800000 openwrt-ixp4xx-zImage
This process should take about 5 seconds,if you get any errors then make sure you have the tftp server running correctly and that the file you are copying is there, and further that the IP addresses are correct. From the above command you should see:
Using default protocol (TFTP)
/
Raw file loaded 0x00800000-0x00967c93, assumed entry at 0x00800000
RedBoot>
We proceed to create a flash image which we call 'linux' from the the file we've just loaded from the tftp server.
RedBoot> fis create linux
The output should be
... Erase from 0x50080000-0x50280000: ................

then need to
We now need to copy the root filesystem from the tftp server as raw data (option -r) to memory address 0x0080000 (option -b) and want a progress indicator (option -v). Type the following command;
RedBoot> load -r -v -b 0x00800000 openwrt-ixp4xx-squashfs.img
The output is:
Using default protocol (TFTP)
/
Raw file loaded 0x00800000-0x00d13fff, assumed entry at 0x00800000
RedBoot>
We once again check to see the available flash space
RedBoot> fis free
  0x50180000 .. 0x50FE0000
Therefore we have 0x00EF0000(about 14.7MB) of flash available.
 
We then proceed to create an root filesystem image onto the FLASH using the entire available space.
RedBoot> fis create -l 0xe60000 rootfs
 
The output should be:
... Erase from 0x50180000-0x50fe0000: ...................................................................................................................

... Lock from 0x50fe0000-0x51000000: .
RedBoot>
 
Finally, we run the ''fconfig'' command to write the boot script and also make any changes we may need.
RedBoot> fconfig
For our purposes we will only specify the boot script and leave the other settings unchanged by entering the "Enter" key. The boot script we will enter is:
 
>> fis load linux
>> exec
Hit the "enter" key twice after the "exec" word.
Enter Y or y when prompted with
Update RedBoot non-volatile configuration - continue (y/n)? y
The complete output should be:
RedBoot> fconfig
Run script at boot: true
Boot script:
Enter script, terminate with empty line
>> fis load linux

Now we reset the Avila board
RedBoot> reset
 
 
Linux should now be booting. After a long display of messages you should see the message:
mini_fo: using storage directory: /jffs

After which it prints
Please press Enter to activate this console.
If you happened to have missed these above messages and it appears as though the board has "hanged" you need to hit the "Enter" key to see the prompt.

End!!
===NOTES===
In the above the steps, the root filesystem and the kernel were two different files. In the section on downloading and making our own customized images, we'll show how to combine the two files into one, so that from Redboot we only load one file instead of two.
 
== Configuring the Avila board ==
===Configuring the Ethernet ports ===
By default(from the downloaded images), the two Ethernet ports (eth0 and eth1) are not configurable since their hardware addresses are 00:00:00:00:00:00
root@OpenWrt:~# ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:00:00:00:00:00 
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
eth1      Link encap:Ethernet  HWaddr 00:00:00:00:00:00 
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
 
On further inspection, I found that the reason why the hardware addresses are 00:00:00:00:00:00 is because the network drivers for the LAN interfaces were neither loaded (as modules) nor created during compilation!  A solution to the above problem is to download (svn) the source (either the trunk or kamikaze) and then make sure that the LAN network driver modules created/loaded.
 
===Working from the source code===
Create a working space from which you run:
svn co https://svn.openwrt.org/openwrt/trunk/    ///To download the trunk
OR!!!
svn co https://svn.openwrt.org/openwrt/tags/kamikaze_7.09  ///To download the kamikaze release
 
The following steps apply to either the trunk or Kamikaze. After the above commands are done the run:
$make
OR!!
$make menuconfig
 
====To merge the kernel and root filesystem into one image====
During menuconfig, select '''ramdisk''' under option '''Target Images'''. Save the configuration, exit the menu and type '''make''' again.
$make
The build process will take a few hours since it has to download the sources and only then it build the images.
 
After the build process, in the '''bin''' directory you will have either two files '''openwrt-ixp4xx-squashfs.img''' and '''openwrt-ixp4xx-zImage''' or only one file '''openwrt-ixp4xx-zImage''' (provided your selected '''ramdisk''' as you '''Target Image''')
 
'''NOTE: Ramdisk means all changes, you make on the filesystem, will be lost on reboot.'''
 
====Load the image(s)====
Follow the steps described above in section '''C. Upload OpenWRT onto the board'''  to load the images. Check the LAN addresses
root@OpenWrt:~# ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:00:00:00:00:00 
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
eth1      Link encap:Ethernet  HWaddr 00:00:00:00:00:00 
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
 
Alas, the LAN hardware addresses are still 00:00:00:00:00:00!!!
====Diagnostics====
When the system starts up, look at the following messages
Using base address 0x00800000 and length 0x0031d030

Apparently this version of Redboot is old which causes it to pass a wrong machine id to the linux kernel; So instead of using openwrt-ixp4xx-zImage as the kernel use the kernel named openwrt-avila-zImage, and everything should be fine.
 
Pheeew!!!

So here's the short of story of the above

===Customizing the firmware===
To include your startup scripts do:
 
1) Create a directory called '''files''' in the trunk/top directory
 
2) From within the '''files''' directory create the subdirectory(ies) and store the file in the appropriate directory
 
3) Rebuild the firmware
 
 
Examples, to have a passwd file in the /etc/ directory do:
mkdir $(TOPDIR)/files/etc/
cp passwd $(TOPDIR)/files/etc/passwd
To have your startup script called '''myinit''' do:
mkdir $(TOPDIR)/files/etc/
cp myinit $(TOPDIR)/files/etc/init.d/myinit
Please note, for startup scripts you MUST at the beginning of the file define the line START $NUMBER
 
e.g.
START 40
This will cause a file '''S40myinit''' to be created in directory /etc/rc.d/
 
====Passing kernel commands at boot time====
By default the kernel is passed the following commands:
root=/dev/mtdblock2 rootfstype=squashfs,jffs2 noinitrd console=ttyS0,115200 init=/etc/preinit
The above parameters are specified in the '''kernel_menuconfig" option of make, so do:
$make kernel_menuconfig //then select the '''Boot options''' option
 
===Network connection===
I've compiled in the firewall, which by default blocks all incoming connections. For now simply switch off the firewall
root@OpenWrt:/# chmod 666 /etc/init.d/firewall
root@OpenWrt:/# reboot
====Kernel error when loading linux kernel====
I now enable wireless interface wifi0 from file ''''/etc/config/wireless'''.
config wifi-device  wifi0
        option type    atheros
        option channel  11

Kernel panic - not syncing: Fatal exception in interrupt
 
Now recompiled the images, first without the madwidi drivers but then the wireless interfaces were not configurable. Then rebuilt the images with madwifi back in; and so far the kernel panic has not occurred. I will need to investigate further as to what causes the kernel panic.

3) Web server configuration
 
Either by hand or within the startup script of udhcpd, do this:
mkdir -p /var/lib/misc
touch /var/lib/misc/udhcpd.leases
Otherwise udhcpd will fail to start.
root@OpenWrt:/# udhcpd -f /etc/udhcpd.conf
 
udhcpd (v1.8.2) started
udhcpd: can't open '/var/lib/misc/udhcpd.leases': No such file or directory
udhcpd: bind: Address already in use
 
If you see this error message
udhcpd (v1.8.2) started
udhcpd: bind: Address already in use
Then do this
root@OpenWrt:/etc# netstat -l
and if it shows
udp        0      0 0.0.0.0:67              0.0.0.0:*
Then most likely you need to stop dnsmasq
root@OpenWrt:/etc/rc.d# sh S60dnsmasq stop
Here's the configuration file '''/etc/udhcpd.conf''' stub
# replace these with your own ip address range as appropriate
start 192.168.1.2
end 192.168.1.250

                # match the IP address of the interface specified here
# these options are for bootp.. PXE uses this to figure out which server to

#
# This scheme of calculating IP addresses is based on two observed patterns:
#  1. The Ethernet addresses for first Ethernet port(eth0) of the Avila boards differ on the 6th byte.
#  2. The Ethernet addresses for Atheros cards (we have, so far) differ on the 6th byte
#
#  So, for the IPv4 IP address,A.B.C.D,
#
#  A -- is fixed, currently set to 10
#  B -- is the 6th byte of eth0's MAC address
#  C -- is the lowest nibble of the 6th byte of eth0's MAC address, for interface eth0 only
#    -- is the 6th byte of the wifi card's MAC address, for wifi interfaces only
#  D -- is fixed to 1
#
#  E.g. For eth0 with MAC address 00:D0:12:03:24:67,
#      Interface ath0(wifi) with MAC address 00:80:48:4F:24:DA
#      Therefore,
#            the 6th byte is '67'
#      Implies;
#              eth0's IP address is 10.103.3.1
#              ath0's IP address is 10.103.218.1
#
#
#
#  Returns A (which is always fixed) in IP address A.B.C.D
#

===Booting from Compact Flash===
Kamikaze doesn't support Compact flash. So I got the latest source code branch (8.09) from Openwrt:
svn co https://svn.openwrt.org/openwrt/branches/8.09
 
I've created (using cfdisk /dev/sdb) four partitions on the 128MB of 32MB each.
  cfdisk /dev/sdb
Then I created I ext2 file systems for all the the paritions using (mke2fs /dev/sdb1,2,3,4).
mke2fs /dev/sdb1
I copied the Linux kernel into the first partition (cp linux /dev/sdb1) and copied the root file system into the second partions (cp rootfs /dev/sdb2)
$cp linux /dev/sdb1
$cp rootfs /dev/sdb2
 
Redboot script used so far:
 
>> load -r -m disk -b 0x01600000 hda1:linux
>> load -r -m disk -b 0x00800000 hda2:rootfs
>> exec -c "rootfstype=squashfs,jffs2 noinitrd console=ttyS0,115200 init=/etc/preinit" 0x01600000
 
Default kernel command as set in kamikaze (make kenerl_menuconfig) is:
root=/dev/mtdblock2 rootfstype=squashfs,jffs2 noinitrd console=ttyS0,115200 init=/etc/preinit
 
 
DEFAULT BOOT SCRIPT ON AVILA BOARD
RedBoot> fconfig
Run script at boot: true
Boot script:
.. fis load ramdisk
.. fis load zimage
.. exec
 
 
USING RAMDISK
RedBoot> load -r -m disk -b 0x01600000 hda1:linux
Raw file loaded 0x01600000-0x018f662f, assumed entry at 0x01600000
RedBoot> exec -c "rootfstype=squashfs,jffs2 noinitrd console=ttyS0,115200 init=/etc/preinit" 0x01600000
 
===Things to do===
* Find out how the kernel scans for Mini-PCI slots. That is, how does it determine which slot to name/assign interface '''ath0''', '''ath1''', etc.
* Configure udhcpd. '''Done!!!!'''
* Ensure '''eth0''' does not accept DHCP-offered addresses when plugged to a network. At the moment it accepts IPv6 address.
* Ensure '''eth1''' doesn't respond to DHCP requests. Although '''udhcpd.conf''' should do this!!!
* Submit to OpenWRT that
root@OpenWrt:~# hostid
Segmentation fault
*Create startup scripts for all services needed, batman, udhcpd, etc.
*Find out if dnsmasq is needed, if so then resolve conflict with udhcpd.They both seem to use port 67!!!
 
===NOTES===
====Identifying the Mini-PCI slots to interface names====
With the board facing up and the Ethernet ports facing away from you, the slot on your left (Top Left) is  scanned first, followed by the slot on the right (Top Right), followed by the slot below the first slot (Bottom Left) and lastly the slot below the second one (Bottom Right).
 
So if all slots are filled with cards you will have:
 
Slot 1 (Top Left)    -- ath0
Slot 2 (Top Right)    -- ath1
Slot 3 (Bottom left)  -- ath2
Slot 4 (Bottom right) -- ath3
 
However, please note that the assignment of interface names ( i.e ath0, 1, 2,...) depends on which device is found/detected first. I.e. if slot 1 is empty, then ath0 will be on slot 2, ath1 on slot 3, etc.
 
==Features of the High Performance Node (HPN)==
===Network configuration===
====Ethernet Network====
*'''eth0'''
**Identification: This is the port closest to the power injector.
**Function(s)  : It provides power over Ethernet. It is used to respond to DHCP requests.
**IP address    : IP address is fixed.
*'''eth1'''
**Identification: It is the second port on the board
**Function(s)  : It receives DHCP offered IP addresses when plugged to a network
**IP address    : It has no fixed IP address. (Apropos!!)
 
====Wireless network====
*'''ath0'''
**Identification: It's connected to a first 5GHz antenna
**Function(s)  : Provides backhaul
**IP address    : IP address is fixed and is determined/calculated based on the MAC address of the interface.
**Channel      : TBD
**SSID          : TBD
**Mode          : Ad-Hoc, 11a
**Security      : None(??)
*'''ath1'''
**Identification: It's connected to a second 5GHz antenna
**Function(s)  : Provides backhaul
**IP address    : IP address is fixed and is determined/calculated based on the MAC address of the interface.
**Channel      : TBD
**SSID          : TBD
**Mode          : Ad-Hoc, 11a
**Security      : None(??)
*'''ath2'''
**Identification: It's connected to a 2.4GHz antenna
**Function(s)  : Provides hotspot
**IP address    : IP address is fixed and is determined/calculated based on the MAC address of the interface.
**Channel      : TBD
**SSID          : TBD
**Mode          : Ad-Hoc, 11b/g
**Security      : None(??)
**Other        : .
 
===Services running on the HPN===
*DHCP server - udhcpd
*Routing protocol - Batman(batmand)
*Web server - mini_httpd
*Web security - HTTPS and authentication
 
==Misc==
===Compiling user applications for mips/LinkSys===
Go to the top directory of your openwrt tree and run:
make menuconfig
Select Broadcom for the "Target System"
 
Select LinkSys for the "Target Profile"
 
Then run
make
 
Then to compile the helllo.c use
staging_dir_mipsel/mipsel-linux-uclibc/bin/gcc -static -o hello hello.c
Note "-static" is VERY important!!!
 
=Linksys Development=
==Upgrading LinkSys to Mesh Node==
Using your novell account logon to '''tera2'''; go to directory '''/home/lmboweni/''' and copy file '''freifunk-ipv6-en-1.6.22-11March2009.bin''' and upgrade your Linksys.
 
Features in this version of the firmware:
--Router will only work in an IPv6 backbone(d) network.
--Peer-to-peer applications are handled by an 4over6 application
--OLSR running is set to version 6
 
===Making changes to the running system===
 
Changes to the running system can be made through '''nvram''' settings or directing editing of the configuration files.
 
'''Switching off the 4-over-6 application'''
$vi /etc/olsrd.conf.temp
remove or comment out the line '''''@@hna6ip46address@@'''''
$cd /etc/init.d
$sh -x S74over6
$reboot
