Once the moduloes for the fast kernel are all posted, maybe a bunch of us should document 'em..and maybe turn 'em into ipks and pop 'em into a feed on externe and/or anyerlildog2? It would probably be of use.

I'll be happy to host them. Send me a mail with the files you want to host on my gmail.com account (guylhem) I'll put them in the flash section. I'll also upload a new backup script to create the same files one can find in the 1.12 rom. (I'm using these files to look where the mtd parameters are given but they can also be used for a complete restore)

Regarding the filesystem I made good progress. I'm now using my hack for everyday use and it seems to work reliably (rw /, got rid of most of sharp garbage). I'll try to have that posted too, but I'd best like to release everything at one (big 64M partition + rw /). I hope we can create something cool for most needs (X, qtopia on flash, qtopia on SD)

PS: could anyone send me a "strings" binary or ipk ? My net access is problematic at the moment (I'm deep in southern France - villeneuve d'aveyron in aveyron)

Asd I said I had "flattened" much of the sharp qtiopia. Now, I'm thinking that If (and I'll play w/ this for the next couple of days) cacko lite could be adopted (I'll know if it's too much of a headache pretty quick, I suspect) that w/ basic xqt2 might be wedged into the 64meg nand w/out insane linking.. either way, I should have some basic thing done with a normal linux tree within the week--it just requires drudgery..following the links, putting the files back where they belong, removing the mystery subdirs (like /home/root/modules --why anyone would feel that to have been necessary....!)

Then again, kdrive doesn't look like too much of a problem to compile...... decisions, decisions.
Probabky I should just get working and see what I can actually make work

edit: RW / would make use of devfs workable, right? that would be a real improvement in the way things are done...

adf · « **Reply #154 on:** March 23, 2005, 01:24:43 am »

the modules (and some completely useless stuff... sorry, I didn't get it all cleaned out) are uploaded as linux-2.4.18-rmk7-pxa3-common-20041002.tar.gz. 2 kernel variants are there too.
good luck

guylhem · « **Reply #155 on:** March 23, 2005, 03:27:19 am »

Thanks ads - will put the module on externe.net if you're ok. But don't lose time on the root filesystem- I already have that working, I'm currently working on the 64 Mb partition before releasing it.

I've only done some links only for var and tmp to avoid useless flash wear (they are sharing a shm partition)

adf · « **Reply #156 on:** March 23, 2005, 01:07:32 pm »

can you send me a loadable 64meg? nand image? Woking w/ the 64 meg might make life easier.

I'll get on it asap (been kinda sick the past few days)
By all means post... what I uploaded is crufty and undocumented... can be sorted easily though.
Going cacko will be work..will stay with sharp for now.

edit: er.. did you mean you alreeady got the rootfs setup? (lots of cold medicine)

guylhem · « **Reply #158 on:** March 24, 2005, 10:30:45 am »

I got a correct rootfs, mostly fixing up etc and root. I'm manually checking everytinh - it's at least a couple of days away from a release, but if you want I can send it to you.

It fits on 32Mb because I'm still experimenting with the 64 Mb partition part (found where I had to make changes !) - it could cause total data loss if I don't find a way to fix at the same time the the normal and the rescue kernel (cause one would want to make 2 32Mb parts, the other one 1 64 Mb part - boot one kernel the other kernel and you'll kill your part).

Fixing both at the same time is not a problem, making sure everything will perfectly work at once is, because I won't get a second chance if things go bad - can you say "bricked" :-)

So I'm carefully studying all that.

adf · « **Reply #159 on:** March 24, 2005, 11:07:41 am »

PLease do.

32 meg should be fine for a base fs anyway.

I had wondered about problems w/ that 1st kernel.

Mostly, I can do some drudgery and save you some time for the more difficult stuff. Also, I was kinda hoping to use devfs (if it works) If we are going to set things up from scratch maybe a standard kernel doing stuff like devfs (and w/ built in support for the hardware --might mean n, l, w versions) might be worth a look.
Have you got the image somewhere that I can ftp it from?

guylhem · « **Reply #160 on:** March 25, 2005, 05:42:56 am »

PM me your ftp info and I will upload it.

Regarding devfs, you will have to change the /etc/rc.d/rc.rofilesys (which I already heavily changed)

I also removed the various .xxx_default.tar files that were taking approx 4 Mb just for offering a safe restore option. Reflashing is just as fast :-)

"Regarding devfs, you will have to change the /etc/rc.d/rc.rofilesys (which I already heavily changed)"

er... is this needed change likely to be self-evident? do your changes cover it ( I was assuming they did--that basically i just need /dev to be rw) do you have a suggestion

I guess I'll see this weekend.

ps.
Anything I should know re service menus, etc... if, for example, I decide to do a "q,t, reset" reset-to-sharp-default-from-cf will my Z suddenly become insane? same w/ "d,p,reset" restore form image?
Basically, are there any known problems in reset/restore/maintenance/diagnostic options?

What are the chances of this modified kernel and ROM hacks turning into something so straightforward and simple that an idiot like me could install it?

adf · « **Reply #163 on:** March 25, 2005, 04:31:11 pm »

My motivation is personal idiocy. I have a hard enough time doing "regular"linux. "sharprom embedix" is a relative nightmare. The idea is to make the system more manageable, more versatile, but most importantly more comprehensible. The wizardry here is on Guylhem's end, patching the kernel source and changing the NAND format structure and doing the SDL stuff. In the end there should be something that is quite simple to flash, and simpler to use and expand.

xjqian · « **Reply #164 on:** March 25, 2005, 06:50:33 pm »

Thanks guys. I'm looking forward to the "neat" rom and the instructions that i can understand. Let me know if anything I can help, usually limited to documentation and testing stuff

Shall we give it an official name?
