We successfully compiled and installed Android on the mini2440. The gui reacts once if we click on the slider but is very very very slow and hangs up if we start an application. Might this be a framebuffer problem. Is there anybody who uses the mini2440 with a 7'' display and android successfully or anybody who has experiences with the 7'' display? Regards Austin
can you tell me what is step to download android on mini2440 7" inch . where i can get the image for this 7" friendly arm for android ? i am having the zimage of 3.5" android but i m unable to compile it for 7" inch friendly arm regards Asad
I also have a mini 2440 with a 7" display...Please tell me how can I do to install Android...I found some information but still I can't install onto mini 2440... Thank you Carlos
Hi all, I have Anroid zImage for 7". I will try to upload and get the link for you. Its working but very slow as mentioned by Austin. Can you tell me how is the performance in 3.5". Regards Saravna
Performance for 3,5" is also poor, but you can make some experiments with create swap on SD card or try to play with zram driver (swap in RAM). This things should speed up android on mini 2440.
Yeah the whole Android thing on the 2440 is not great performance. Thats why I'm giving up now to look for answers getting cam130 to work in Android. I think the camera will just freeze the damn thing. But isn't the performance better with running the OS in nand? Is there someone who could tell me that? Or maybe a temporary fix is to lower the resolution of the 7inch lcd, I dont know. Oh and the originial android 1.5 does not support such high resolutions I think, so...Im just coming up with ideas, my knowledge isnt so great to give solutions... Regards (maybe I should change my name just for the convenience lol)
Yes, Carlos. I also started work on driver to enable FM radio (AR1010) with android in Mini.( Just to have diversion since got bugged up with fine tuning Android in Mini). Hi Open-Nandra, I tried and enabled Swap with my SD Card. But Android uses it very little. So no improvement. Let me explore zram and see. Let me know if some interested in 7'' Image .( Working but slow) I will spend time to upload. Regards Saravana.
Hi Sarvana, I'd like to try android on my mini2440 7". Please upload the zImage somewhere. Kind regards Luc
Hi Luc/All, Below is the link to get 7inch Android working Image for mini2440.(But Slow) http://androidport.blogspot.com/2010/09/mini2440-7-android-image.html try it and give feed back if it works. Regards Saravana
Hi Saravana, I've left you a msg on your blog, the file is corrupt I think. And how slow is it, because I've seen a video on youtube about a guy who made it work. it went from 30sec reaction time to about 1sec if I remember correctly, so just wondering.
Hi Carlos, I re-uploaded the zip file. Can you check and let me know. Regards Saravana
So...I tested your images. Still the same question in my head: what is the reaction time? It seems an eternity, really. Or is the touchscreen mirrored?(seen that before) I cant see, because everytime I boot Android, I get an error msg about the settings proces. I can't click that away, so I cant do jack in the system to test it out. At least the screen looks good and sharp :P ..ok I started tapping round the whole screen and got the msg away, testing right now..still can't figure it out, guess its too slow, cause I tap so much I cant see where it worked. Could you tell what exactly you've changed? Regards
Hi Carlos, Yes.. Even I got setting message but i'm able to click it away.I even able to play mp3s. I'm booting from SD Card. How is your setup. You can also try kill the process from the command prompt. Regards Saravana
Hi Saravana, Yes I can see the homescreen and even slide the screen across the 3 homescreens. But I'm only able to click the clock, in the right-top-corner! (While I'm still seeing it in the middle of the screen.) So I havent figured out yet how to click on icons...anyway, we need to fix this. My setup is just like yours I guess, booting from SDcard. Anyway, I still have to figure out how to compile a working uImage, I tried it once now and the system didnt boot Android, it showed the linux-logo and stayed there. (terminal saying: ...booting linux. STUCK) What am I doing wrong? Regards, Carlos M.
Carlos, Did you get the Calibration screen at First Login. My Guess is your 7 inch is not calibrated correctly. If you haven't done calibration recently I suggest to do it first. To invoke calibration at boot up, you have to delete(or rename for safety) the file "/etc/shine/pointercal". Let me know how it goes. I used different point from Below two links to compile http://androidport.blogspot.com/2010/09/mini2440-7-android-image.html http://code.google.com/p/friendlyarm/wiki/Linux_Tutorial If I get time I will try give in steps in my blog. Regards Saravana
Hi again, Hm I'm no pro at this, on the contrary, I just followed the stepbystep tutorial(s) and got Android running. And started to dive into the code a little. I have different folders with the android fs, but I never see pointercal. I DO have another folder somewhere, called something-mini2440-master where the file IS available. What are those files for exactly, do I need those? How else do I get the calibration screen... (I think its still calibrated for the 3.5" because when I tested the 7", only half the horizontal resolution worked. Or is it maybe something else I have to change, except the images?) Carlos M.
Hi Carlos, or try to find within /system/etc/shine/pointercal.
Hey Saravana, I have no pointercal, folder or file. I have 3 files within ../shine: - myInit.rc - net.conf - wpa_supplicant.conf P.S. I downloaded this archive a while ago where the file is in. Could you tell me what these files are for? --> http://gitorious.org/android-mini2440/android-mini2440 Because I see files in there which arent in a default Android fs.
Ok..Let me double check where "pointercal" file (its not a directory)..and get back to you. To answer your question (as far as I know) ... myInit.rc will executed when adroid boots ..you can set Path etc..here. net.conf has your network configurtion like IP address etc..wpa_supplicnt.conf must be for WIFI password I guess. Regards Saravana
Yes I kinda figured that out myself, but I ment the other files from the link I gave. I can see a pointercal file in there, but its not on my sdcard along with many other files. I think I have never seen pointercal in all my 'versions' of the Android fs. Carlos M.
Hello friends I have mini2440 with 7" TFT I have installed android OS which come with Board DVD. but it is working very slowly, so is there any solution to make it fast? - Regards, - Himanshu
hello, I have installed the 7" version of Android as described here: http://androidport.blogspot.com/2010/09/mini2440-7-android-image.html But the LCD (A70) remains dark after power up. On the terminal it says: U-Boot 1.3.2-mini2440 (May 25 2010 - 19:15:21) I2C: ready DRAM: 64 MB Flash: 2 MB NAND: 128 MiB Found Environment offset in OOB.. USB: S3C2410 USB Deviced In: serial Out: serial Err: serial MAC: 08:08:11:18:12:27 Hit any key to stop autoboot: 0 MINI2440 # but that's all. The SD card is inserted of course. Any ideas or suggestions? Thank you for your help! Mathias Tantau
Did you hit any key and stop autoboot? Or, it that all that happens after powerup?
hello davef, even if I do not hit any key, there is no further output via RS232 and the LCD doesn't display anything.
> even if I do not hit any key The word <even> here implies that normally you stop the autoboot process, which I think it not what you want to do. However, considering your problem . . . are you trying to boot the kernel from a SD card? If so, how did you set that up? Dave
Hi Dave and others, I have got further now: It starts booting! For all who face the same problem, follow the description here: http://mini2440.spaceopera.org/site/developmentenviroment/stepbystep/ind... The next hurdle now is this error: Failed to execute /linuxrc. Attempting defaults... Kernel panic - not syncing: No init found. Try passing init= option to kernel. Allthough mentioned in other threads, I couldn't manage to solve it. In easy words please, what to do?
Mathias, I quickly read through the link . . . it is quite long and I see he does NOT describe how to partition the SD card. So, again I ask how did you do this and are you sure it is working correctly? Dave
hello Dave, to prepare the SD card, I created three partitions with gparted: Partition 1: LINUX-SWAP Partition 2: EXT2 (UIMAGE files) Partition 3: EXT3 (Android and Kernel files) this is described here: https://sites.google.com/site/belina76/android-booting Again, booting works fine up to the point, when this error message appears: Failed to execute /linuxrc. Attempting defaults... Kernel panic - not syncing: No init found. Try passing init= option to kernel. What to do? Mathias Tantau
Mathias, Ah, reading closer I see gparted will do this for you. I used a script, probably because I couldn't get gparted to work! Failed to execute /linuxrc was a common error message in many past posts. No clues found searching this site? Dave
