sorry to keep adding posts lol -

just wanted to mention, in case someone else wants the various nand tools, compiled binaries of mtdutils (yes I was too lazy to cross-build it myself) I got from here:

aaaand a little more spam from me:

so I got nanddump sorted with oob, but dumping the mtd nodes still mostly looks like garbage (ok it's not pure FFFFFFFF content, I see some pointers here and there to UBI filesytems - great...)

also tried using yaffsexpert (as mentioned a couple months ago by vicinc in another thread) - hoping it might "do the right thing" with the mtds - but the resulting images look no different than dumps using dd, dump_image, nanddump. blah.

fed up with it again (and it's late here), but when the irritation subsides I guess the next step is seeing if the dumped images (or the mtd nodes themselves) can be mounted as ubifs.

have you looked at the bluepanther development I mentioned before. seems same platform, same s... cpu etc...

(I suspected I could get the internal sdcard flashed with a dingo upgrade, but wasn't thinking)

Open to brilliant ideas... or this might be a "lab device" which sits torn apart so I can get to everything.

How good are you with a soldering iron?

Just remove the old switch and replace with a new one.

If you go the replacement route make sure you have a temperature controlled iron and it has a fine point tip, that way you are much less likely to damage the circuit board and bridge tracks.

Anyone know the part number of the switch or a compatible replacement part? I've been trying to get a replacement, but do not know what I can replace it with. That way I can get my other PE back in rotation instead of being on injured reserve

I feel your pain.

Been looking for a replacement switch too.

You need to go somewhere like this http://uk.rs-online.com/web/c/?sra=o...itch&x=22&y=14 and check through the descriptions to find something that will fit.

If you could supply a *good* photo I might be able to suggest something as a replacement - it is rather difficult to do without seeing the item in question.

I'll post a pic as soon as I can. At work now. I've been slogging though such sites looking, so hopefully a pic will be worth a thousand words and you'll be able to suggest something.

thanks... yes, it looks like you guys have already found out all the good infos... once again wasting my time and yours lol.

ok, obviously I'm late to the party here: you're right, the GM10/bluepanther does have the same (well very very similar) ubi fs layout as the Edge, rather than the more traditional android use of mtds. however, its recovery, while still a little lame vs what most users would want, is less "crippled" (to use someone else's word) than the Edge - you can replace uboot, for one!

given how different its recovery is, not sure how much its sdk will help us, at least not until our crazy serial ubooters have a better idea how the Edge boots up.

It looks like Edge's update.zip does replace u-boot.

tarvoke · 10-13-2011, 01:06 PM

oh good point, it's right there in update.sh ... I need to stop with the drugs ha...

JRANGER · 10-13-2011, 02:38 PM

Damn yall are smart on this..Im in IT (sys admin) and did VB programming....Where can I learn how to do this stuff? I want to help but at this time the only thing I can contribute is graphics for future roms, bug testing in the future and anything yall ask that i can research how to do on Google...Let me know how I can help

Just in case yall havent seen dudes post

Pocket Edge Hardware/software - LONG - TECHNICAL
I spent some time this afternoon poking around the guts of my Pocket Edge, this is what I've found.

The internal storage (all parts of it) is a single flash chip which appears to be 3.5 gig large.
Its broken into 4 pieces ubi:system, ubi:userdata, ubi:cache and ubi:storage

ubi:storage is mapped to /intstorage and is the 2.5 gig of free space.
ubi:system -> /system 322.2 meg
ubi:userdata -> /data 322.2 meg
ubi:cache -> /cache 322.7 meg

I think with a custom update (if we figure out how to do that) and if people move there storage to sdcard we can cut up the storage differently to increase app space. ubi:userdata is where our installed applications end up.

The really interesting stuff is in ubi:system
/system/app - all the APK's that the edge ships with
/system/bin - standard linux stuff
/system/esi - this is that holds the eink/annotation software system startup stuff

esijournal/esicalender/esireader applications attempt to connect to the WACOM DSU (most likely a WACOM 8001) which is a pen enabled touch sensor that goes under a display.

all 3 go through the same startup (and error out since I'm remote)
Connect to DirectFB (this is a low overhead display manager, probably to get the different tool bars etc)
Connect DirectFB to WACOM DSU (touch screen)
Connect FBDev - DirectFB (800x800 resolution)

GDK is also involved - this is a drawing kit for displays and probably provides the windows of the menus/toolbars - possible part of the annotation feature as well.

start_epd.sh
Turns on power save mode for the Marvell processor
init_wacdsu - drives the wacom dsu i'm guessing
sd8688.ko - Wifi/Bluetooth

Loads kernel modules
syscopyarea.ko - makes a bit copy of a FB - this is probably our save for annotation
sysfillrect.ko
sysimgblt.ko - makes an 8 bit source into a 32bit image (copy to lcd feature)
fb_sys_fops.ko - underlying frame buffer read/write to memory

ep3522fb.ko - (nonstandard - possibly eink display driver? referenced as EPD_MODULE) - this looks custom from the brief peak I've had.

bmm.ko - (nonstandard - unknown at this time google bmm_drv.ko shows up some stuff for Marvell Dove)

reference to thirdeye (there is also an application named this) and loads udlfb.ko
udlfb.ko is a driver for Displaylink (displaylink.com) which is a usb based monitor technology
this is our driver for useing a projector I see people talking about?

Another kernel module of note is galcore.ko driver from Vivante Graphics GPU

esi_init.sh calls fix_permissions.sh which is based on this blog post to fix some Android problem
http://blog.elsdoerfer.name/2009/05/...id-mismatches/

QCUdevScript.sh - looks for a 3G modem we don't have probably useful for external 3g modems.

Here are some photos of the power switch. Hopefully they will give you some idea of a replacement part.
