Apparently I still need a little help. I am not sure of two things.
1.) Which mk802 I have. Mine has a barcode on the back that says "MK802A-1" Which kernel should I download for that?
2.) I following the installation instructions to the letter, using the two partition option. /dev/sdb1 is FAT32 500MB /dev/sdb2 is EXT4 7.12GB
no errors were generated. I used the mele kernel rather than the mk802ii.
When I put the micro SD into the MK802A-1 and powered up it booted straight to Android (which performs miserably on this device). Should I try the kernel for the MK802ii and if, so do I need to redo the uboot step or just swap the files out? Sorry it took me so long to get back to this project, I don't have consistent access to the device as my wife is generally using it to stream music or video when I have time to work on this.


There seem to be at least three different mk802 models:

mk802
mk802-1gb
mk802_A10s

Can you tell us if your model has 512mb or 1gb memory?
Can you take a look inside and check if your mk802 has a A10 or a A10s cpu?
With this i can build you specific script.bin and uboot for your device

Have you tryed booting alpha 3 iso?

Here is the link to what I bought on Amazon:
http://www.amazon.com/gp/product/B008H3B736/ref=oh_details_o09_s00_i00?ie=UTF8&psc=1
It does have a label on the back of the device that says "MK802A-1" I don't think I can get it open without breaking it. I definitely has the 1GB of RAM listed in the specs at Amazon.
Sorry it took so long for me to get back to this.


I made a image for mk802_1gb. it comes with mele kernel and mk802_1gb u-boot/script.bin. It's a 1gb image. Just write the image to a sd card and try to see if it works.

Exynos rocks!

If you have a spare $100 (and an HDMI telly) get an odroid-u3. I mean it.

This is damn fast... and I mean it makes my athlon 2100+ look like the POS it is.

It was a bit of a challenge to get working because there was some problem with the uboot-u2.bin so I had to overwrite that with a blob from this site.

EDIT: Only a matter of hours after making this post, jamesbond fixed the uboot image and provided new instructions in the README for dd command and I can confirm it works!

Sound,video and all work BUT I had to force module loading (in rc.local) and it didn't work from uEnv.txt, maybe PEBKAC error. I have this:
Code:
loadmodules=fuse,ipt_MASQUERADE,iptable_nat,nf_conntrack_ipv4,nf_defrag_ipv4,nf_nat_ipv4,nf_nat,nf_conntrack,ip_tables,x_tables,bridge,bnep,stp,llc,smsc95xx,mousedev


I translated that to a loop to load on startup then connect to the net manually once I bring up eth0.

I did have res problems on my crappy old aldi HDMI enabled panel TV ("vivid" 21") but managed to add this to uEnv.txt:
Code:
video=video=HDMI-A-1:1280x720M@60

Still has some overscan (underscan? Well it's a little too big for the display, that is I can't see all of top, bottom, left, right for only a few pixels, quite usable though).

I tested sound, works through HDMI. Yay! One thing we could not get to work with raspberry pi. I tested an html5 (webm encoded) video and picture is fine, no sound. I think its either a bug or a config miss in seamonkey. For the record, Slacko (32) Firefox-17.11 plays sound with said video, compiled by PV, and he is a stickler for keeping things "free", good on 'im too. Its a shame same can't be said about Samsung, Broadcom and all the other ARM vendors.

Did I mention this is fast?

pedro, thanks for helping.

You need to put the "loadmodules" parameter in "extras=", e.g:
Code:
extras=loadmodules=blah blah blah[

... but, there is a limit on the length of the line; if the line gets too long it gets ignored by uboot. Exactly how long - I'm not in the mood of reading uboot source code yet, but I have on occasion exceeded this limit and wondered why it didn't have any effect Smile

PS: smsc95xx is compiled as built-in, so you don't need to load it.

For the TV, I used "JustScan". I still get some lost pixels in console, but in Xorg, everything looks intact.

For HTML5 sound - it can be made to work. Let me know how it goes.

Yes, you did, this just an example: seamonkey took 15-18 hours to compile on the original Mele; it took a wee over 2 hours on this thing. It is *unbelievably fast* for a chip the size of your thumbnail and runs without fan.

Hmmm.. maybe I should have figured that (re extra=) Embarassed

Ok Smile .. I was just going off a list I made in ubuntu.. may have missed some. However it does seem like module loading is somewhat hampered.

Yeah.. works with Sammy.. Aldi(='vivid' model)? Nah!

Yes..! Works. Apologies for presumptuous crap in previous post.

It sure is impressive!

HTML5 is very impressive, as long as you don't go fullscreen. (YouTube etc). This seems to be a limitation of the video driver. Not much can be done there.

I plugged my ucv webcam and after installing mplayer seems to work ok, a bit of latency. Dunno how to work it Xine. Which brings me to a bug. Xine works perfectly playing many formats, but as soon as you go fullscreen it crashes.
Code:
root:~/smb/Video/Cloud_Babies# xine "Cloudbabies Sun's Very Own Sunset.mp4"
This is xine (X11 gui) - a free video player v0.99.7.
(c) 2000-2010 The xine Team.  ##### PRESSED "F"

Note the "PRESSED "F"" comment.. mine.

Mplayer is just no good. Too slow. Doesn't crash (even full screen) but can't keep up. Explains my latent webcam result.

Now.. ffplay is perfect! (Yes, I am playing over network.. shouldn't matter). once upon a time I worked out how to play a DVD in ffplay.. but there is so much variation in the proprietary crap they put on DVDs that that avenue is definitely not worth pursuing.

This command works perfectly for webcam:
Code:

It will take a while though as it is a full rebuilt. (No, I don't just change glibc). Meanwhile, alpha4 is very usable. In fact I'm building the beta using alpha4 Smile




Hi!!
Does your kernel for the Allwinner A10 support f2fs ??
Thank you!
J.




WELL...
I THOUGHT THIS WAS A FAIRLY SIMPLE AND EASY QUESTION...
BUT IF NOT EVEN 007 IS ABLE TO ANSWER IT, I JUST HAVE TO APOLOGIZE FOR ASKING....
PROBABLY I AM TOO DUMB!
THANK YOU ALL !!

jota no reply from JB007 ? That can be a good sign. He usually only post where there is compiling issues I suspect since that is a filesystem most needed in ARM systems and would not have any issue compiling.
I fully expect that that file system would be default image by final, my SDcards are already showing the slowdown problems caused by over use of key areas and the remapping behind.

On ODROID kernel...

Code:
root:~# gunzip -c /proc/config.gz|grep -iE f2fs
# CONFIG_F2FS_FS is not set


So that would be no. I don't know about other kernels.

if you guys get a chance pop over to geexbox and see if you can follow how they got the hardware blob from android to decode video In mele hardware, sound like they are supporting like hardware for the ARM as we are...
also they have a hybrid boot with EFI for 64bit. I can't hunt around there anymore Its too easy to hit a download link. And GeexBox is no longer tiny like they once where... now down to vapors on data plan.. If I suddenly disappear from the forum u know why !

Just curious, what packages work with this? If I can afford it, I might get an MK802-II off eBay and start playing with this.

Also, is a 2gig microSD card big enough to do anything useful? That's all I have right now Sad may be able to get an 8gig from WalMart but no promises... it depends on what price it is when I have a little money again.

@ 01micko, Ted Dog

Thank you!

I myself tried to compile the A10 3.10-experimental kernel from linux-sunxi.org, but did not manage to make it work.

What I find very strange is the owner of this topic - 007, did not bother to answer my question... maybe we could have exchanged some ideas and progress a little further.

But now I will rest my Cubie and do other stuff, at least until I have new ideas to try to make f2fs work.
J.

Here is a very simple wall paper setter with preview in ~54 lines. Should be able to handle spaces also.

Just add some wallpapers to /usr/share/backgrounds.

Code:
gunzip wallset-0.1-noarch-1_FDA.tbz.gz
then install with

installpkg wallset-0.1-noarch-1_FDA.tbz

Very happy that tunneling X over ssh logged in as 'mick' (oh yes multiuser is working quite well) is working perfectly. I'm on my slacko64 box typing this on seamonkey running on the odroid. Very fast actually (probably because there is next to zero network latency). Zero lag in typing this message, probably attributed to the speed of both systems as well as the close proximity (network wise).

Razz

(ha.. while typing this had to scp over the screen cap Wink )

The reverse is also true with the brand new slacko64-5.8.8 which includes dropbear server/client. Smile

That's xine for you. Try to change the video output modules; try XVideo, SDL and XShm. XShm usually always works. I'll try to build vlc next time.

Firstly, I was away on a mission and secondly, what you asked is highly classified. I could tell you but then I would have to kill you. I would rather not do that Laughing
But you can rejoice now, the powers that be have decided to de-classify them after somebody leaked that vital information. Rolling Eyes

Here is the answer you seek:

No, none of the FatdogArm kernels support f2fs at the time being. For odroid, it's rather easy enable f2fs - flick the configuration item and recompile the kernel. For Cubie/Mele, it is a bit difficult because f2fs support isn't there; I will have to backport the patches for 3.4 kernel that 01micko gave me a while ago. That being said, please read the last comment on this page: https://github.com/nowcomputing/f2fs-backports/issues/1.

What usage scenario do you have in mind? Some of us can probably help to compile the packages you need.

It depends on what you plan to use it for. I used 1GB card and 40GB external harddisk to build FatdogArm Alpha from the scratch (that 40GB disk is 10+ years old).

General desktop use was what I had in mind, just fooling around to see what performance is available from an MK802-original. (Performance is something I have to gauge for myself. What's slow for you is often fast for me Wink )

Basically:

Chrome or Chromium (with full capabilities including flash and extension support -- I'm on Chromium31+Pepperflash right now, off these very forums)
LibreOffice (or a nearly identical substitute)
Some sort of professional vector art program (better than Inkscape, needs to support Corel *.cdr files)
Printing support for Canon and HP printers (including printing 11x17 paper for Canons; the HP is an all-in-one)
Scanning support for HP and Xerox scanners (the HP is that all-in-one, and the Xerox is oooooold but works nicely)
Wine would be super amazing but I'm not expecting it... although if it were there and performed reasonably well, it'd take care of the vector art program requirement Wink
Music player
Picture viewer (I like Viewnior, a lot -- hint, hint)
Support for USB flash media (not bootable, just for files)
IceWM support would be nice (but I realize that it's not likely either). It's pretty Razz (I'm an artist. Pretty matters.)

Mostly I'm a web-browsing and email dude. I do write stuff occasionally, and I do vector art occasionally. I listen to music a lot. I'd like to see if I can do everything I use an x86 system for, on ARM.

I'd get an ODROID but I don't have the money and I don't really have a way of saving up Sad (that was my ulterior motive in asking you a while back what would become of the ODROID you have, once you're done with it -- I was hoping to get it for a song, but I realize now that it's not happening.)
