Moto Hell - The Motorola Modding Community

Hi every body.
I'm coming from E398 World and i've got a brand new rokr e2.

The first thing i've done with my new phone was experience flashing and the linux embedded OS.
I've also manage to install the sdk provided by lasly. Everything sounds really good.
Now i'm ready for a further step in my investigations/research.
I don't know if somebody could provide a detailed specification of the QT classes used and/or an sdk for our embedded OS (openezx i think). Since QT implementations differs from device to another, these would be very helpful if somebody want to convert existing applications such are those related to this project (Opie) :http://opie.handhelds.org/cgi-bin/moin.cgi/Applications (http://opie.handhelds.org/cgi-bin/moin.cgi/Applications).
Anyway, someone got news of feasability of porting this project to our Rokr e2? I know that someone is working on the motorola A1200 porting; Since this device is very similar to our (OS, screen, etc...), i wonder if you guys know if the porting could be envisaged in a near future.

Sorry for my bad english, i'm originally french speaker.

Oh, one last thing, don't hesitate to fwd this topic onto another forum if you think it could help. Just pm me if it's the case.

Cheers.

Most (or all) of the developers are currently located in China and Russia. They do not share a lot of information for their work - just suddenly releasing some gui application...

I don't think that the mentioned project is researched yet. Our E2 SDK is very new discovery (it was released just few weeks ago). We will need some time :)

;D no, it's not suddenly, just you don't know he is doing on that
and, actually, in it168, we post the applications with full source

Can you repost some of them here? Currently the English tutorials are not very complete

unfortunately, it168 is a chinese site, so international contribs are quite difficult.

But i'm sure those guys have lot of stuff they can or wanted to share. Since we are on a GNU/Linux OS, i think it would be benefit for everybody to share their knowledge.

For example, can you ilove3d provide if you have it , the QT library documentation you use to provide all show** modules?

i plan to work on a pdf viewer for our phone, and i would like before starting to collect all needed developpers stuff. This is why i started this topic. but shhhh... it's still a secret   ;)

Keep it up guys.
E2 rox

I know how to use those modules/binaries; I could make a guide or something.. but... let's wait for 3d's answer ;)

all the source code of show* you can find here : http://moto.it168.com/viewthread.php?tid=110918
or see the attach:

Those QT modules are from official QT/Embedded or a fork?
If it is from Qtembedded library, then i am sure that not all classes are implemented. My problem is that i want to know what is usable and how to use them.
A sort of class diagram for the graphical layer of our phone i mean.

ps: @houhq - it168 is in japanese isn't it?  :P (i mean i dont understand a word in chinese, and the google auto translation is ... berk )

*EDIT* Found this on trolltech web site: http://trolltech.com/products/qtopia/qtopiainuse/qtopiadevices
 I will try to download the Qtopia core phone edition and related stuff. Will tell you later  if something interesting can be extracted from these.

no, motorola modified the qte libraries of E2, it's not offical qtopia ones

lasly has did a non official E2-EZX-SDK

you can download from the internet, learn about the source of the show*** or other non official qt apps' source, I think it's easy enough to build our own qt apps by lasly's SDK

i have shared all source which i wrote. they are to simple...but easy to understand.

Moto have modified many classes in QT 2.3.8 include QWidget, and it is a hard work to find out which class can be used on E2.

the E2's native sdk has lots of weak but it can be used to build some base app.

i think the header files is easy to understand by their name, and i have not enough time to write a document to descrip how to use it except anyone can help me.

sorry for my poor english. ;D 

Hi Lasly, nice to meet you here

Your sdk is very good - some people already use it around. We (or I) will be happy to contribute into project for documenting the work with the SDK. Please let us know what is needed from our end?

if you have read the header of the sdk include files, you may notice that the include files is mixed by qt 2.3.8 's header file and some i wrote(named by "E2_...").

some qt header files can't work or maybe to cause link error, and "E2_..." files have a lot of notes block(the "/*....*/" block). the functions in block is existed but i don't test their usage, or include some another classes i don't crack.

maybe we can start at test the unused qt header( if it can link by couldn't work, means need to modified), and find out the usage of the functions which are in block...

emm....

Hey lasly, I'm glad to read you here ;)
hmm... that must be a team work; it's too much for only one person
but still I need to read and practice a lot to be useful  u.u'

Hi Lasly.

nice to meet you. I've already downloaded your sdk, and as you said, it is a very good point to start (although it is a little painful to get a working cross sompilation environment). As you noticed, and i was almost certain that motorola would not completely open its firmware. So, we are in a situation where only reverse engineering could help us to get a complete sdk with low level primitives.
As i said in a previous post, i will try each class of the qtopia core library (i've downloaded v4.3)  and see if it work on E2. It's a long job so, i'm not sure i could provide results, but hey .. life is not easy isn't it?

Anyway, thank you for your shares guys.

C Ya!

hi, hotus

your work could do base on qte 2.3.8,which is e2 used...

We can post updates in this thread for each discovery. It is stickied

I have tried opie on my E2 and obviously, it doesn't works...
I tried the one designed for EZX and here is what happened:
The 64mb swap file was created successfully but nothing seems to happen after that... A folder called opiehome was also created...

This is the log file:
Creating swap file /mmc/mmca1/opie/lib/swapfile (will only do it once)..
/dev/loop0 /ezxlocal/opie cramfs rw 0 0
/mmc/mmca1/opie/lib/swapfile file 65528 3808 -1

Here are the files you need:
http://cyph.ath.cx:8080/downloads/ezx-opie.zip
http://cyph.ath.cx:8080/downloads/opieproxy.tar.bz2

wow!
Really great news sjj.
stop me if i'm wrong, but the ezx version of opie wasn't designed for A780?? As they have diff. hardware parts,  i think  we have to recompile the kernel including hardware drivers dedicated to e2.
I checked at openEZX.org (http://www.openezx.org/) and the completing status  for E2 is very very low.

Althought due to lack of time, completion status is 0% for retro ingeneering QT implementation of motorola E2. :(. Hope i'll be more productive in the next days.

It was designed for the e680i and the author said it was not tried on other EZX phones...
I didn't expected it to work anyway...

Hi!

Anyone experienced cross-compilation with cygwin?
Since i've lost my pc at home, i'm not able to use native linux in order to build/test progs/classes.
So i'm trying to create a working environment with cygwin, but since now , i wasn' t abe to make it work.

Regards.

LZ you can go to     moto.it168.com   and you will saw a big family   Again where you can enjoy the full opensourse  of happiness

nice ads :)

 :( and for those who doesn't read/understand chinese??.
If you got the answer , please tell it here, don't send people to unknowns lands.

dion, from motofan.ru told me that there a way to run QT4 apps on ezx phones, he did it on e680i and can make it work on e2 too, but he is busy now... maybe he will share the way :-)

Hey,I don't know...but i think we can use Brew SDK to build applications for E2???

You can try that and tell us if it works...
