The following text appeared after flashing:

Recovery system v1.3.28

Formatting DATA:...

Formatting CACHE:...

Formatting uDisk...

Formatting PAGECACHE:...

Reboot

You're right, system partition is full (see attachments). Now, it just bootloops, so i can only control it with adb (poweroff) to reflash.

Is there any way to format /system before flashing?

Hi! Szia!

I flashed my tab with another rom and it's work. I am not at home now, i think i can help, but just tomorrow.
[Android Software/Hacking General [Developers Only]] fun_:
please show me parameter file in your update.img.

please tell me list of files in /cache too. it should be almost empty.
[Android Software/Hacking General [Developers Only]] lisovszki:
So.

First of all I downloaded this Yarvik image (it's have the same hardware like your, and mine Alcor e-pad):

Unofficial CyanogenMod7 port for RK2818 tablets packaged for yarvik tab210 v2 (29082011)

And replaced the boot.img and system.img with the 20111013 boot.img, system_xy.img

Its works for me, so I hope it will work to you too. Or try the Alcor rom.

Another Rk2818 project:

[Android Software/Hacking General [Developers Only]] Ziyan:
I attached the contents of update.img, without the images.

I'll check /cache later today.

lisovszki:

Thanks, i may check them out when we find a solution :D

[Android Software/Hacking General [Developers Only]] fun_:
which ver. did you try? did you modify system.img?
[Android Software/Hacking General [Developers Only]] wetware05:
Hello, I have a problem that I cannot have the control of the directory for system.

Cause can't system put on his directory in rewritable?, How can it be done?

I have installed Superuser, but that does not work to give privileges of being able to write on this directory

Thank you very much.

What happens if I press the "Erase IDB" (IDB = ID Block i think) button in RKAndroidTool? Would it format /system, or what?

system.img form 13 of oct...gapps added
[Android Software/Hacking General [Developers Only]] ^BatVanko^:
The system partition in this ROM is cramfs formatted which means it's readonly. You cannot modify the filesystem while it's mounted.

There are few alternatives that can be used to make the system writable:

1. Use a layered filesystem such as: UnionFS, aufs or mini_fo, Which run on top of the readonly filesystem. These filesystems allow you to modify your readonly fs by storing modifications on another writable fs. There are some performance concerns related to them.

2. Change the system image format to some writable filesystem such as: ext2, ext3, yaffs or yaffs2, jffs2 etc.

The common requirement for both solutions is that you need to have a kernel support for the filesystem (module or built-in). The current rk2818 kernel supports only ext2, ext3 and cramfs (correct me if I'm wrong). This is not a big problem as long as you have the kernel sources and you can build a kernel module for the filesystem support.

Here comes the other obstacle - there are some platform limitations/checks which doesn't allow you to use ext2/3 or yaffs filesystems. I'm not very familiar with them and maybe fun_ has more experience and give us the details.

Cheers,

BatVanko
[Android Software/Hacking General [Developers Only]] fun_:
I guess it erases protected area which stores bootloader.

if you really want to solve your issue, don't rush, don't do random things blindly.

how about /cache contents?
[Android Software/Hacking General [Developers Only]] fun_:
if no gapps added, i.e. flash my system.img w/o change, wifi works?

I remembered truncated uid/gid issue, which doesn't happen on my N2, but you may need to change permission... anyway, please check step by step.
[Android Software/Hacking General [Developers Only]] fun_:
I have no info about kernel config on all rk2818 tablets. but probably "ext2/3 or cramfs" is almost correct.

I'm not sure detail but MTD driver is something strange. /dev/mtd/* don't work correctly. so I guess any file system sit on raw MTD device e.g. yaffs2 will not work correctly.

everything are just my guessing. it should be confirmed carefully. but I have no time & rw /system is not so important for me.
[Android Software/Hacking General [Developers Only]] Ziyan:
Ok, i'll slow down :D

Now, i've deleted some unnecessary apps from system/app, like livewallpapers, camera, sound recorder, etc.

After flashing, and pressing 2 or 3 Force Close button, they disappeared, so i calibrated the screen. After reboot, only one FC appears, but I cant close it, because it appears again, instantly... :confused:

As you said, I also checked /cache, not sure if I did it right, please check the attached zip. From what i understand, it's trying to store dalvik-cache on /cache, which is full, not on /data, which has lots of free space.

I see this text in logcat when i press Force Close:

Well, i'm a beginner in Android, so i may be totally wrong :D
[Android Software/Hacking General [Developers Only]] fun_:
/system should be enough large. cramfs is always displayed as 100% full.

20MB /cache is too small with current configuration. partition size can be changed by editing HWDEF and parameter. but using /data for dalvik-cache also solve your problem.

if you want to change dalvik-cache location, add following line to build.prop

dalvik.vm.dexopt-data-only=1

probably many other rk2818 tablets has enough /cache (e.g. 116MB on my N2) and smaller /data.
[Android Software/Hacking General [Developers Only]] Ziyan:
Adding that line to build.prop fixed everything!

Big thanks fun_, my tablet is now flying :D

Well, I have one more problem, but it's not too important ;) WiFi only works if I set manual ip, gateway, etc. in the settings, otherwise it freezes at getting ip address, so I think DHCP is broken. I only use wifi at home, to install apps, so it's not a big problem for me, but some people suffer from this problem too. I attached a bit of logcat, recorded while trying to connect to my open network, so you can check if you find something useful in it if you want :)

it seems "black screen on resume" happens if USB is connected to PC. I'm not sure it happens on other than ONN N2. anyway, workaround is easy, disconnect USB :)

I uploaded 20111029 as regular(?) release. changes/site update will be done later.

I have a RK2818 based tablet (ONN N2), and I need the pl2303.ko module in order to get a usb-serial interface up. Where can I download the kernel sources to compile it with the module enabled?

words on sunday

I think the world is not divided in dev-people and non-dev-people. Thats too easy fun_, there are lot of colours in between. Nice speech, but who do you think that really cares about your words for a sunday church. Don't be so arrogant to think, that all look at you.

Most of us are here for the fun or the challange to get a better rom and talking to friendly people, somestimes evil jokes/black humor are included.:D Some devs maybe try to get their business running here - okay. Some want to ask stupid questions - feel free.

But the most important thing is, keep a sense of humor. There are lot of cultures around here, working good together and we have to accept that fun_ will maybe never laugh about himself. Maybe its a difference in culture.:rolleyes:

currently GPS module(software) is not exist in my image. I'm thinking to add it which supports NMEA from serial. there is simple source for SDK emulator, and probably better one in android-x86 (originally from freerunner project).

or you use serial tty node directly from app?

This is not fair. First of all: read the forum etiquette and read all topics around the web about forum etiquette.

Please realize that we have a forum here that is used by many people for whom english is not the native tongue.

As a result of that: due to (sometimes huge) differences in language structure and culture, the "so delicate and subtile" jokes that are made on this board are indeed not funny to others and even insulting, whereas jokes "native to them" might be very funny to them but definitely not to you.

That's exactly why these forum etiquettes/rules have been put in place that tell you to keep away from "humor" in forum discussions.

Please keep that in mind and keep the discussions clean.
[Android Software/Hacking General [Developers Only]] DaremoS:
Ok I accept what you say and I ask to be forgiven...

but if your read this contribution maybe you could understand why I don't feel happy with this person fun_... arrogant, offensive and despising the work of others.
[Android Software/Hacking General [Developers Only]] surfer63:
Well: this is going to be a long post.

I have seen it and even though you seem right, I can imagine why he said it. Currently it seems that he is the only one really compiling the stuff for the RK2818 tablets and trying to improve it with here and there a patch from a helpful user. You can't imagine how much time it costs to do this developments and have to test your changes over and over again. Time that is actually his free time as he most certainly has a study or job during the day time.

I have been a long time maintainer for several MacOSX Open-Source packages and still am for three. I spent hours and hours and days on it trying to improve it (and I can fully imagine it's the same for fun_). Many users wanted to help and some did, but most did it as test users, which is also extremely useful and appreciated but it still keeps the development part on your shoulders.

But: some users "demand" you to do things you are working very hard for, but simply can't get to work or not yet. It's not a paid job. It's all voluntary! Asking for new features is not a problem. It sometimes gives you even new ideas about things to implement or solve other issues.

And: other users even blaim you for stopping or slowing down certain developments and that's really very frustrating and demotivating if you spend so much time on trying to improve it.

Again: The post you refer to might indeed not be very communicative but it is coming from that same frustration, disappointment and demotivation: so yes, I understand and I am thankfull that despite all the criticism and "jokes" he keeps going on (for the time being).

And be honest: who can take over his work at this moment? It's not arrogance (or maybe a little), it's a fact at the moment. A lot of the more technical users can take over but it also means that they have to spend an awful lot of time in getting there.

To finish with: I know that most users are simply thankfull for the work, also the ones that joke a little about it or have some criticism.

(And yes: english is not my native language either).

Not 1:1, but with some tweaks certainly.

Someone made already a custom rom for the Arnova 10. See here and as far as I know the 10 and 10b are equal (or not?)
[Android Software/Hacking General [Developers Only]] JDfense:
Thats tough speech surfer. Forum without any kind of humor to keep the discussions clean. This is cruel. Why are you so straight like the forum police? In the forum rules I haven't found your politics so strictly, but of course you're right in one point: We have to be careful with words and it is not easy to hold the borderline. Personal rights are very important, but without humor life will be a piece of ****.

The forum rules said:

»Tolerance is a two way street.« Give us a bit air to have some fun. And fun_ could talk for himself, when he wants to come out of the crying corner.

[Android Software/Hacking General [Developers Only]] DaremoS:
You are absolutely wrong if you believe that this guy is the only one doing ROMs for RK2818... you can go here http://xdaforums.com/showthread.php?p=13503105 where there are many like me doing thing, most of them before him... we have succeeded making companies take our work and use it for their products like bqreaders and all their line of Froyo for their products..

You can go to Archos Forum and you'll find the same. There is hvdwolf and some others.

Or you can go to http://www.yuandaocn.com/BBS/ where are lots of developers dealing with Gingerbread 2.3.1 for RK2818.

What fun_ do was to port CyanogenMod CM7 for RK2818, obtaining a partial success as the ROM is incomplete as it's not capable of play movies: This is the core of this arguing: people is asking for this as a normal request, it's supposed that a ROM should be capable of play movies.

No offence, no battle... just a request... a very normal request.

On the other side are we: the non-devs (as pompously call us Mr FUKAUMI Naoki (fun_)), researching, investigating, testing... and failing some times as it's to make this CM7 or my CM7.1 play movies.

Trying to get our "glorious goal" as sarcastically said mr. fun_ (he indeed believe he have reached such goal)... and that's his problem.

we aren't searching for a goal!!!

We want our devices playing videos in a very good version of android as it's 2.3.4 and above (supposedly written from scratch by Google)... we have noticed this in version 2.3.1 which is very good and we expect that is even better in 2.3.7.

No glory!.. no money!... no fame!... no stupid and false pride... just our devices with the best (no idea what is talking fun_ about donations... this is for us a hobby).

Is Mr. fun_ who is searching for such glory and recognition... is he who have been fighting and posting everywhere that some people is stealing his creation... when in fact he is also part of chain that tries to not re invent the wheel. I recall some Leferdedieu walking the same road.

As he recognize that he being a dev (developer) won't succeed trying to play movies in 2.3.5... we, the "non-dev", try to do our best... and we surely know how much efforts and time take this. We don't have time to refute Mr. fun_ or claim that he stole our work... what for?... why we gonna do this?... he has the glory... we intend to play movies. :)
[Android Software/Hacking General [Developers Only]] surfer63:
I fully agree with that!

As such I also agree with that. Like you say: »Tolerance is a two way street.«

That's what I'm striving at and that's why I mentioned that mis interpreted humor can break that as tolerance comes with understanding (each other). I definitely mean mis interpreted humor, certainly not humor with bad intentions.

Yes. Peace :)
[Android Software/Hacking General [Developers Only]] JDfense:
Daremo there is nothing more to add. You got the point.:)

Maybe we get back to solve the video problem or figure out some small issue in the cm7 for rk2818. But one day we will find the trick.:rolleyes:
[Android Software/Hacking General [Developers Only]] surfer63:
I agree with you.

Next to that: I'm hvdwolf on forum.archosfans.com but I didn't want to mention that here. surfer63 is just a very old synonym from the glorious days* when I really spent many hours on my surf board.

[Android Software/Hacking General [Developers Only]] fred61:
hi!

i have got an arnova 8 and flashed this firmware at the end of september i think.

the only reason i did it was that in my rooted 2.1 rom the market didn't work. my feeling was that it was much slower than my old 2.1 rom.

- i wasn't able to get access to the internal storage of my device

- there was always less free ram than with 2.1 rom

- youtube and videoplayer didn't work

- orientation didn't change

- usb flash drives weren't recognized

etc. etc.

Please don't get me wrong. I don't want to say that this rom was useless but my old rom was more handy. so i flashed back to the old rom. at this time arctablet announced that there will be a froyo rom with working market for arnova 8 soon.

but arctablet is so busy in producing new roms at the moment that there is no froyo rom to date.

now my question: shell i try this Gingerbread Rom another time or shell i wait for arctablet's Froyo Rom which is especially made for the Arnova 8?
[Android Software/Hacking General [Developers Only]] JDfense:
Your question isn't easy.

This cm7 should be fast and stable on your tablet and the access to the internal flash should be no problem.

If you need video, you have to wait until someone solve this problem. Have you tried fun_'s advices about accelerometer axes for the touchscreen?
[Android Software/Hacking General [Developers Only]] birdiebnl:
I synched the sources yesterday (gingerbread branch) and now the build gives an useless rom, everytime the "black screen on resume" happens, also when not connected USB to PC. Only way to get out is using the "hard reset". This is on my Archos HT7V2. Very frustrating... Anyone else experienced the same problems? (or knows a solution?)

Probably some things have changed around sleep and resume?

As fare as I understood your discussion about synchronisation, you mean the profil sync over an Google E-Mail account?

Anyway here is my experience to that point. With fun_'s rom I have learned to switch off the google profil sync option, because sometimes I got a unstable rom installation as result.

I don't know how to fix it and it is in my opinion a small failure.
