Openzaurus For C1000 And C3000, First Open Source ROM for CXK released Options

[iamasmith]

Since there are only two kernels on a Zaurus, I suspect the emergency kernel is zImage2 - the same as used when you are updating the device. When you zero the device there's probably no kernel running at all, since this seems to be completely implemented in diagnostics code.

Speaking about that... I'd really like to have that code released

Zeroing is handled on Sharp ROMs by the /root/etc/rc.d/rc.rofilesys

It picks up some parameters which seem to be added to the boot process by using option 3,1 on the Japanese menu.. it does actually boot into the live Linux when you do this. If you wanted to implement this for OZ then you really need to look at that file..

Look around this area.....

CODE

....
#ZAURUS_RESET=HARD
if [ "$ZAURUS_RESET" = "HARD" ]; then

STRING=$"Starting filesystem: "
msg -n $STRING

# mount /home
/sbin/eraseall $RW_MTD 2> /dev/null > /dev/null
mount -t jffs2 -o rw,noatime $RW_MTDBLK /home
cd /
tar xf /root/.home_default.tar
....

Hope this helps the efforts,

Andy

I don't see why we should use this in OZ. We have /home on the harddisk, not on a mtdblock.

Wasn't particularly hinting at the mtdblock.. if you take a look at the whole script you will see the HDD handling in there too for zeroing the device.

what you seem to miss is that there's a fallback linux install somewhere else that doesn't seem to be affected by OZ (and it shouldn't as far as I can tell).

It's quite a normal question IMHO, I'm not afraid to flash the NAND, i've done it before, I'm just wondering about how the proces works.

We might not have missed that had you actually asked this in the first place. Your original question:

Is there an easy way to get back to the original Sharp Rom?
