Hi!

Fabian, what model do you have? As far as I know nobody has tested this installer with a 700. In the rest japanese models it works.

Have you tried what Zazz says? If so, can you post and attach mtdnand contents or your actual offset?

At last I found a few minutes of free time...

Here is the pdaxrom modified installer fixed for 860s (just added 1 line :roll: )

Has anyone else ever tried this on a C860?

Not yet, I presume. You seem to be the first...

For me the new installer stopped with the message:

Flash pattern NOT recognized. Cannot patch flash.

Fortunately, I wrote a pre-patch check routine to ensure that can be done without risk :wink:

I browsed a little through updater.decoded to figure out what went wrong and eventually found that if I change MTDCMD from 0X209F4 to 0X20A0C it would work, and in fact it did so without bricking my precious.

As there are so few differences between 760 and 860, I didn\'t thought this to be one, but actually it is. Thank you for testing, investigating and posting the actual 860 mtdparts offset! I\'m going to update this on the installer, very easy.

Is there any documentation about things like the scrambled updater.sh format or the boot process in general?

I posted source from endecsh, the encoder-decoder app, in previuos downloads. I don\'t know why Sharp made this silly encoding to installer.sh. The boot process is somehow described in several topics, this one has some info we know as well, but I don\'t know any complete reference (wiki, howto...)

I assume that an almost full partition is bad for wear levelling, all writes can only be distributed among the few free blocks, so that\'s another good reason to have only one partition.

You must be right  , that is something I never thought  :wink:

Thanks, OpKnight. I thought so, it was a pity to waste the nand due to partitions and limits. I thought it even before installing the very first version of pdaxrom (2003 cacko x11 roms mounted root as a compressed loop, just like qtopia, and it was needed, but not now). And I agree with you, nand is muuuuch faster than flash cards...

Hi dvdrw!!

Sorry for the delay in posting, now my job keeps me much more busy :?

Thank you very very much for testing and making necessary mods for me!!

It\'s true, I forgot to make the changes about non-maintenance 750 kernel

p.s. as there is no longer any mtd3 it is possible to eliminate the bootup warnings about mtdblock and mtdblock3 not found by commenting out the relevant statements from /etc/rc.d/rc.rofilesys (e.g., RW_MTD_LINE references, etc)

Also, you should remove mtdblock3 line from /etc/fstab :wink:

I\'m very happy it works, and that you tested and corrected it!

And, people, DARE trying it! There could be still bugs (surely for 700, not yet tested), but for 860/760/750s seems to work perfectly. So don\'t be afraid. The installer is very careful before anything is done. And the beneficts for me are obvious: I have many many apps installed just in my nand and have still a lot of free space!

Maybe, I should remember that after installing pdaXrom with this installer you\'ll get 100MB free nand space on a x60, which can be much more thanks to jffs2 zlib transparent compression. As an example: in my z, df is saying I have 60MB used, 60MB free (!!) and \"du /\" says I have 105MB used !!!!! (no cards in)  Should I say anything else...?

Hi everybody!

I\'ve just rebuit my installer to work properly with 750s, thanks to dvdrw\'s headaches. :wink:

To use it, just substitute installer.sh from pdaxrom, and add mtdparts & mtdtweak to your flash card, like prior version.

Zaurus sl-c750 need to update their maintenance kernel, as we have discussed in this topic, in order to be able to mount *big* jffs2 partitions. So, the first option you must select from the installer menu is \"4 Update SL-C750 Maintenance Kernel\". Don\'t worry, it makes a backup copy of you original maintenance kernel into your flash card (named mkern750.bak); if you want to get back, option \"5 Restore SL-C750 Maintenance Kernel\" restores it when ever you want. The rest steps are as prior version: resize to only root and install, which can also be reversed as you now. I try to write the most careful code I can, \'cause we are playing with fire :wink:

Reply for bugs, congratulations, insults...

The new installer is only available in the following attachment.

PS: Thank you again ikm and dvdrw, this won\'t be possible without you

Foxdie, have you tried to completely remove VERSION.BIN line from updater.pro? I think it isn\'t an important thing to reflash, as a matter of fact the file contains only 0xFF bytes. I\'m presuming that if it is not referenced into updater.pro, the NOR restore won\'t try to flash it.

Congratulations dvdrw!

many thanks to ikm and ashley who made this possible for this happy user

You are welcome, but you are the main cause of your succeed.

Now, I want some feedback, in order to update installer to work with 750s  :wink:

I\'ve rebuilt the \"shepherd\" kernel but have defined the HUSKY config define for the jffs2 code. everything built fine, but I am not sure where to flash zImage in the updater.

Can you mail me zImage? The one you built works, and not sure if i can compile it correctly. I can\'t ever test it.

I tried flashing over the second kernel image location at 0x00220000 but that killed the device (even the \"d+m\" reset appears dead.)

What extrange. Did you reflash to a different location later? Or what did you do to make it work?

I\'m trying a \"c+d\" CF recover now to un-brick it...

Did you succeed doing this too? Fabulous! Maybe you can post a howto for Foxdie to this topic: http://www.zaurususergroup.com/index.php?n...iewtopic&t=2897 he seems desperate.

And finally, i\'ll need that you confirm the offset of mtdparts in a 750. I think it\'s all what i need to make a 2nd version of installer suitable for that model. Now i need a 700 voluntarious user :wink:

Oh man, i look like your boss!

ikm, you are THE root!

The outcome: you can\'t use standard maintenance kernel on C750 to create one big root partition. You will have to reflash it.

Ok, now we are sure: it is the only way.

How to fix the kernel: remove the aforementioned conditional statements there, leaving only the C760 code. This way it will most probably work

Or just try to flash a unflashed 760 kernel, as I told. Seems to be a quicker solution :wink:

This is exactly what I am thinking...I hope I can figure out a workaround for this. Note that I have only been trying the mount with the maintenance kernel. Could you tell me how I could boot with the pdaXrom kernel and try this?

You can try to make a big jffs2 file system on a sd or cf with a running pdaxrom. You must have one, since you are reflashing :wink:

If this works, you may try the only solution I find: update maintenance kernel. This, of course, is very risky and you can brick your z :? , but you seem to know what you do very well :wink:

I\'ll update to a maintenance 760 kernel. I can mail you a nandlogical READ of mine.
With some cares, you could even restore your mainte kernel with a running pdaxrom, if it goes wrong:
- Before doing any thing, leave pdaxrom in a useful state.
- Make a nandlogical READ of your maintenance kernel. Put it on sd or cf.
- Copy nandlogical tool from maintenance to sd or cf.
- nandlogical WRITE 760 kernel image. Reboot.
- Try maintenance. If everything works, fine, if not:
- Reboot and run pdaxrom (it should, no matter how mainte kernel is).
- Use nandlogical to WRITE back your kernel.

I think this is doable, but it\'s your chance.

Tell me if you dare :wink:

Hi Foxdie!

The log shows there is an error flashing Version parameter. But if you look at http://www.h5.dion.ne.jp/~rimemoon/zaurus/...pic/nandmap.jpg you\'ll realize that updater.pro is trying to put it in the wrong place!!!

Maybe in c700s, as updater.pro says it was tested, Version is at 0x54000, but the fact is that on 750/760 it is at 0x48000.

I don\'t know if this is the only problem you have, but it looks definitely to be one.

You should edit updater.pro, correct this and try again.

Luck!! :wink:

dvdrw, that sounds disconcerting. As your test show, the problem is not concerned with tweaking mtdparts. I think some people reported problems to this forum when tried to make big root partitions on 700/760 with early pdaxrom versions, just like happens to you. I didn\'t pay attention since it is a different problem from the x60 one, as sashz in his wisdom has showed. May be you should search that.
If it mounts ext2 but not jffs2, it sounds like a 750\'s kernel bug. But I understand you can\'t mount with either maintenance or pdaxrom kernel (am I wrong?). If so, don\'t know, maybe the bug is present in both kernels?! Or you just tried to mount with maintenance?
