Mele file storage
Exactly the same issues as v1.2. I can not see anything new, nobody should run this.
However, TMerle has taken this image and made it english, removed the annoying apps, and added Google Store. Huzzah!
If you want to replace the kernel, with the NIC patched kernel, do this:
# wget http://lundman.net/ftp/mele/mele.v1.3.nandc-new # dd if=/dev/nandc of=original_nandc.bin bs=65536 # Use /dev/block/nandc if on Android # dd if=mele.v1.3.nandc-new of=/dev/nandc bs=65536
Now, when I boot, the wemac NIC doesn't work any more (link stays down). But if I replace the script.bin it works again. I do not know which part of script.bin needs to be fixed. Someone with time could look into this. There are only about 20 lines when you diff them, but none in emac area.
# wget http://lundman.net/ftp/mele/mele-1.3-script-fixed.bin # mount -t vfat /dev/nanda /mnt # cp /mnt/script.bin /mnt/script-original.bin # cp mele-1.3-script-fixed.bin /mnt/script/bin # umount /mnt
For those of you who also wishes to make advantage of the ZFS in the kernel, you additionally need to get:
# wget http://lundman.net/ftp/mele/zpool_builtin-1.3 # wget http://lundman.net/ftp/mele/zfs_builtin-1.3 # mount -o remount,rw /system # busybox cp zpool_builtin-1.3 /system/bin/zpool # busybox cp zfs_builtin-1.3 /system/bin/zfs # touch /etc/mtab # zpool import -d /dev/block yourpoolname
Personally, I also recommend:
# cd /system/media/ # mv bootanimation.zip bootanimation.zip-orig
This does not include Google Market/Play Store. Has a strange launch screen that appears not trivial to replace. It is loaded with chinese apps and ad/malware. I would not recommend anyone to run this.
Current status with the Mele A2000, Allwinner A10.
Official release: Android 4 ICS, 4.0.8. Kernel: 3.0.31+
- Video playback 1080p
- MKV playback
- TS playback
- Android market and Games (Angry Birds etc)
Network StreamingFixed. NIC has been patched to allow smooth 1080p steaming
- Audio. The settings; CODEC no sound, but probably on RCA. HDMI choppy sound, unusable. If made to work, only stereo on HDMI. SPDIF not working, does not turn on. (No red light)
- Bitstreaming; Unconfirmed since SPDIF is not functional. But can the hardware bitstream TrueHD, and DTS-MA ?
- 10bit video does not play (not supported by hardware, CPU too slow for software)
- AVI/XviD does not play (not supported by hardware, CPU too slow for software)
Currently, it is no good for mediaplayer. But if all you want is a toy to play youtube, some android games, and only stereo sound, it is definitely capable.
Android 4 ICS wired NIC patch
I have been working on trying to improve the wemac NIC driver in the Mele A2000 Allwinner A10 hardware, which will stutter when playing 720p/1080p over network. The current patch makes it much better, such that I think it is usable now. There is a mynewerimage.img image in the storage area, that you can dd to the nandc device. I will work on submitting the patch upstream.
For example, if you boot miniand image:
# modprobe nand # nand.ko on my storage area too # wget http://lundman.net/ftp/mele/mynewerimage.img # dd if=/dev/nandc of=mele_nandc_backup.bin bs=65536 # dd if=mynewerimage.img of=/dev/nandc bs=65536 # sync # reboot -f
And take out the SD card to boot Android again. If you do this using Android, the device node is /dev/block/nandc
Android 4 ICS official Mele image
The official Mele Android ICS image is out, called Mele_HTPC_Android_4.0_V1.rar which you need to use PhoenixCard to "burn". Once installed, you can use audiopatch1.3.apk to enable some sound features. Otherwise it seems quite similar to A10 firmware.
For those not using Windows, I also made a dd image: Mele_HTPC_Android_4.0_V1.ddimg.bin.bz2  Just dd the whole thing to your raw device.
Android 4 IceCreamSandwich
Update: the non-beta release of ICS4 came out (for the A10, not Mele's release), which has settings/display, and lets you chose resolution
For Unix and clones:
wget http://www.lundman.net/ftp/mele/homlet_4.0_v1.0_20120609_dd.img.lzma 7z x homlet_4.0_v1.0_20120609_dd.img.lzma sudo dd if=homlet_4.0_v1.0_20120609_dd.img of=/dev/sdX bs=1M sync
Where you need to replace X in /dev/sdX by the correct letter for your SD card reader. Now insert the SD card in your Mele, and wait until the LED stops blinking, remove the SD card and restart the device. Et voila! (Read more: ) See I kept the paste URL cos I'm nice! :)
There is also an audiopatch for the ICS4 image to get sound to work. Copy over audiopatch1.2.apk (adb, or physical media) to your ICS4, install and run.
Not convinced it makes any difference for me. Audio appears not to work still.
It appears the contents on audiopatch1.2 is pretty much just libswa.so. Not entirely sure what it thinks to do with it, but if I do a find from root, there is no such library, before and after running patch.
I copied the file by hand:
busybox cp /data/data/com.android.audiopatch/files/libswa.so /system/lib/
and I get sound playing videos with some audio formats now. Like, TV MKV releases.
I purchased a MeLE A2000 from Tom over at aliexpress, and been playing around with it as well. First I wanted to install ICS4, to do that I downloaded the android_4.0.img file from the 'net. Alas, there is a large volume of confusing information on what to do with this.
For the MeLE A2000, I also downloaded PhoenixCardV303(win7) and installed that in my VirtualBox Win7 system, forwarded the OSX USB drive and told it to install android_4.0.img.
After that, I inserted the SD card into Mele, and rebooted.
The power LED will blink RED + BLUE for a while, then power LED will turn off.
Take out SDcard, and reboot MeLE. It will now boot ICS, but only on HDMI@720p.
I can confirm BubbleUPNP + 2160pPlayer will play 1080p MKVs over network. Nice!
I installed one of the Terminal programs, and told adb to use TCP (haven't bothered to open my mele yet). Using adb and the instructions found allwinner a10 scripts I loaded Google Market/Play to the mele.
This refers to the Beta ICS4. Probably is not useful any more, but I will leave it here for reference.
Changing resolution can be done by modifying the boot time scripts that the A10 uses. Usually done on a separate boot partition. For example, the Mele image has the files:
mount /dev/mmcblk0p1 /mnt ls -l /mnt/ evb.bin
git clone https://github.com/amery/sunxi-tools cd sunxi-tools make ./bin2fex /mnt/evb.bin > evb.fex
Edit the file any odd way you want, changing screen0_output_type and screen0_output_mode. See modes here: 
./fex2bin evb.fex > /mnt/evb.bin
If you are running the Android 4 (ICS) Beta that was released, to change the resolution to HDMI 1080p, you can do this. Using either a terminal program on Android (ConnectionBot for example) or the USB Console (if connected).
On the mele root shell
setprop service.adb.tcp.port 5555 stop adbd start adbd netstat -na # Check that it is listening on port 5555
On remote adb machine
adb connect 192.168.xxx.xxx # Put in the Mele's IP adb shell adb> mount -t vfat /dev/block/nanda /mnt/obb adb> exit adb push script-HDMI-1080p60.bin /mnt/obb/ adb shell adb> cd /mnt/obb adb> busybox cp script-HDMI-1080p60.bin script.bin
If you don't want to edit the script file yourself, you can download my prepared one: script-HDMI-1080p60.bin
Since I added ZFS to u-boot for CuBox, and also patched in Samsungs EXT4 patches, I built hno's u-boot to test.
wget http://lundman.net/ftp/mele/sunxi-spl.bin dd if=sunxi-spl.bin of=/dev/sdc bs=1024 seek=8 # Obviously, sdc is my SDcard, change device to applicable. wget http://lundman.net/ftp/mele/u-boot.bin dd if=u-boot.bin of=/dev/sdc bs=1024 seek=32 # Obviously, sdc is my SDcard, change device to applicable.

I wanted to replace the ICS4 kernel with my own, for the nic fixes. These are the steps I took:
git clone https://github.com/amery/linux-allwinner git branch lichee-3.0.8-sun4i make sun4i_crane_defconfig
Check that .config has
CONFIG_MODVERSIONS=y # CONFIG_MODULE_SRCVERSION_ALL is not set
The wemac nic was panicing on boot everytime, until I changed this:
drivers/net/sun4i/sun4i_wemac.c #define PHY_POWER 0 /* was 1 */
From android, I used ConnectBot to make a copy of the 'boot' partition, nandc.
adb shell adb> dd if=/dev/block/nandc of=/mnt/sdcard/nandc bs=65536 adb pull /mnt/sdcard/nandc
Then split it up into kernel and ramfs, you can find split_bootimg.pl my storage area (url above)
# ./split_bootimg.pl nandc Page size: 2048 (0x00000800) Kernel size: 8410564 (0x008055c4) Ramdisk size: 975609 (0x000ee2f9) Second size: 0 (0x00000000) Board name: Command line: Writing nandc-kernel ... complete. Writing nandc-ramdisk.gz ... complete.
The idea is to make a new kernel, that looks roughly the same as nandc-kernel, and re-use the nandc-ramdisk.gz
Once the compile has finished, we make a new image. According to the nandc ANDROID! header, the base address for Mele is 0x40000000
# mkbootimg --base 40000000 --kernel arch/arm/boot/Image --ramdisk ../nandc-ramdisk.gz -o ../mynewimage.img
Now I boot into Miniand image on SD card, use my nand.ko to load the device for /dev/nand*. You can find my Miniand kernel uImage and nand.ko in the storage area too. The default Miniand kernel did not come with nand driver.
# modprobe nand.ko # dd if=mynewimage.img of=/dev/nandc bs=2048 # sync # reboot
and remove the SD card to boot Android. If you want to undo, and go back to ICS4, put nandc file instead of mynewimage.img in the dd line above.
Mele's Wired Network Interface
The wired nic in the Mele is a wemac from Davidcom. It is unfortunately quite poor. You will get decent 100MB speeds from it, but it uses the CPU. If you do any transfers while trying to watch video (including watching video over network) it will stutter for 1080p. Interestingly if you use SD, or USB while watching, it has no problem.
The WIFI driver sits on the USB bus and is not affected by this.
Using a USBEthernet dongle (I tried an Apple brand) also works without issues.
ZFS on Android
I have already ported ZFS to ARM, so that should just work if you compile ZFS with your kernel. But I also wanted to see if I can get ZFS to work with Android. The modules do load ok, but execution does not work:
# cd /mnt/sdcard/ # insmod spl.ko && insmod zavl.ko&&insmod znvpair.ko&&insmod zunicode.ko&&insmod zcommon.ko&&insmod zfs.ko&&insmod zpios.ko&&cp zpool /mnt/obb/&&chmod 755 /mnt/obb/zpool # cd /mnt/obb # strace -f ./zpool create melepool /dev/block/sda1 open("/dev/block/sda1", O_WRONLY|O_EXCL|O_LARGEFILE) = 6 write(6, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4096) = 4096 fdatasync(6) = 0 close(6) = 0 open("/melepool", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|0x80000) = -1 ENOENT (No such file or directory) ioctl(3, ITE_GPIO_IN
and it hangs.
djmount for Android
So one option is to have a mediaplayer with UPNP ability, like that of BubbleUPNP or PlugPlayer. However, both of these do poorly with Mele's remote control. With Bubble you can not click on Directories to enter them, but have to Mouse-Mode in/out to do so.
So one option is to mount all UPNP devices as a directory. Since Mele's kernel already comes with FUSE, I compiled djmount for it (patched version with >2GB size fixed).
% adb push djmount /mnt/obb % adb shell # cd /mnt/obb # chmod 755 djmount # ./djmount -o allow_other /mnt/sdcard/Pictures # No reason to pick "Pictures" I just wanted an existing directory # ls -l Pictures/ -r--r--r-- root root 49 2000-01-01 20:00 devices dr-xr-xr-x root root 2000-01-01 20:00 llink-daemon UPNP Media Server (MediaServer) : 1 # ls -l Pictures/llink-daemon\ UPNP\ Media\ Server\ \ \(MediaServer\)\ \:\ 1/ dr-xr-xr-x root root 2000-01-01 20:00 DVD dr-xr-xr-x root root 2000-01-01 20:00 Game of Thrones dr-xr-xr-x root root 2000-01-01 20:00 Music dr-xr-xr-x root root 2000-01-01 20:00 Video -r--r--r-- root root 14010368 2000-01-01 20:00 movie.m4v
And indeed, if you use the File browser in ICS4, you can just enter that directory, and play any video. Note that djmount is pretty slow on listing directories, and I think we might want to look at speeding that up if we are to use it long term. Also, increase the cache timeout from 60s to something much higher, like 10 minutes.
I wanted to see if the PS3 Eye would work with Mele, and Skype.
# insmod gspca_main.ko # insmod gspca_ov534.ko videomode=13
That makes the camera work with Skype and Zoom Camera app. When I tried one of the 640x480 modes it just hangs, so currently it is 320x240@60.
No idea. The device shows:
# cat /proc/asound/cards 0 [sun4icodec ]: sun4i-CODEC - sun4i-CODEC sun4i-CODEC Audio Codec 1 [sun4isndhdmi ]: - sun4i-sndhdmi sun4i-sndhdmi 2 [CameraB409241 ]: USB-Audio - USB Camera-B4.09.24.1 OmniVision Technologies, Inc. USB Camera-B4.09.24.1 at usb-sw-ehci-1.3, high sp 3 [sun4isndspdif ]: - sun4i-sndspdif sun4i-sndspdif
And we get the device nodes:
# ls -l /dev/snd/ crw-rw---- system audio 116, 0 2012-07-03 14:12 controlC0 crw-rw---- system audio 116, 32 2012-07-03 14:12 controlC1 crw-rw---- system audio 116, 64 2012-07-03 14:12 controlC2 crw-rw---- system audio 116, 96 2012-07-03 14:12 controlC3 crwxrwxrwx system system 116, 24 2012-07-03 14:12 pcmC0D0c crwxrwxrwx system system 116, 16 2012-07-03 14:12 pcmC0D0p crw-rw---- system audio 116, 48 2012-07-03 14:12 pcmC1D0p crw-rw---- system audio 116, 88 2012-07-03 14:12 pcmC2D0c crw-rw---- system audio 116, 112 2012-07-03 14:12 pcmC3D0p crw-rw---- system audio 116, 33 2012-07-03 14:12 timer
But no idea how to tell Android to use the USB device as the main microphone.
# setprop usb.audio.cap.device pcmC0D0c # setprop media.audio.in.mode usb
Neither of those work.
