Angstrom & OpenZaurus / Howto Boot From Sd?

« on: May 17, 2005, 04:40:41 pm »

look here:
http://www.purple.dropbear.id.au/node/view/97
the part about rboot. Rboot is script which allows multiboot from as many as you wish images placed on ext2 formatted SD card. If the script is slightly changed it can read the images on vfat SD card (what I currently use). As mentioned above, the script uses pivot_root to make the looped image be the /-root.

Angstrom & OpenZaurus / Openzaurus - Automatically Mounting Loop Fs

The only ways i can think of to make this work is :

1) to hack /etc/sdcontrol to do as you wish.
2) to change /etc/fstab and to mount the (VFAT) card somewhere else (like /media/VFAT),
    then call a script after the card is mounted which mounts the image in /media/card

FYI: /etc/fstab is _not_ used to mount /media/card at boot-time. Mounting is done by /etc/sdcontrol.

Same is suggested on the page pointed by the link in my original post. I will play a little with sdcontrol script.
Btw, I found this:
[a href=\"http://www.purple.dropbear.id.au/node/view/97]article[/url] ("Customisation of OpenZaurus 3.5.2 (Collie / sl5500 )"), and particularly the part which explains the usage of rboot (I found recent version here: http://mysite.verizon.net/dfsteen/rboot-3.5.3.tar.gz).
Rboot allows different images placed on ext2 formatted SD to be booted. The idea is that the whole internal flash is copied into the image on the SD and then the mounted image becomes the root - / . You can configure which images are available for booting with a .conf file. Well, seems I have to touch the scripts a little so it mounts also vfat formatted SD. Btw does anybody else have used rboot? Pls, share some experience.

Angstrom & OpenZaurus / Wlan - Spoofed Mac Address

« on: April 24, 2005, 04:59:33 pm »

CoreDump, thank you, this works perfectly!

The followin change to /etc/network/interfaces should do the trick:

iface wlan0 inet dhcp
        [...]
        pre-up ifconfig $IFACE hw ether 00:11:22:33:44:55
        [...]

Angstrom & OpenZaurus / Wlan - Spoofed Mac Address

« on: April 23, 2005, 06:34:52 pm »

Hello everybody!

My ISP makes simple filtering by MAC address and IP of the NIC in my PC. Usually, I connect with wireless adaper to the AP at home which works as a bridge to the ISP's LAN cable. But if I have to use another adapter I spoof its MAC address and everything works fine.

As long as Zaurus 5500 is not my primary home PC , if I want to get it connected to internet through the Asus SpaceLink WL-110 CF wlan adapter I must spoof its mac address. It is easy:

#ifconfig wlan0 hw ether XXYYZZXXYYZZ

where XXYY... is the MAC address which the ISP expects. It works, but I would like to know where is the most proper place to make this spoofing permanent (which config files should I change I mean). I am talking about OpenZaurus 3.5.3 with opie.

10x in advance!

Angstrom & OpenZaurus / Openzaurus - Automatically Mounting Loop Fs

Hello everybody!

I have Zaurus 5500 and just flashed with OpenZaurus 3.5.3, zImage-collie-64-0-20050407102515.bin and Opie for GUI.

I have Transcend SD 512MB, vfat formatted. I created 256 MB file on it and formatted it as ext2 file system. I can't make the linux to mount the file at boot time. I searched the forums here and couldn't find aplicable topics. I also tried the steps from here:
http://www.olfsworld.de/software/linux/zaurus/
and didn't work.
Well, what I want to achieve is to keep the SD with vfat fs (so I can use it w/o reformatting with non-linux devices) and to make OpenZaurus "see" a file on the SD as an ext2 (or whatever other suitable) file system and install programs on it.

I guess I am not the first one with such question, but... couldn't find working answer till now.
I also appreciate another useful suggestions for flexible usage of the space on the SD card.
Thanks!
