Ubuntu 12.04 Server ARMHF Image for Mele A1000/A2000

I’ve seen quite a few people who want to use the Mele A1000 – or its brother the Mele A2000 – media player as a server (Sacrilege!). Since recent ARM servers are running Ubuntu 12.04, and Tom Gall has (conveniently) posted the live-build config necessary to generate Ubuntu 12.04 Server image this week, I thought I’d give it a try on Mele A1000.

The image generated is a headless system running Apache 2 and sshd (openssh_server). I’ll detail the steps I followed to generate this image first, so if you just want to try the SD card image, scroll down at the end of the post.

The first step is to generate Ubuntu Linaro Server rootfs, by following the Live-Build instructions on Linaro website together with Tom’s live build config. I’ve followed those steps in a machine running Ubuntu 12.04.

Let’s install the required packages:

Configure the build and start the build:


After a while, you’ll get the rootfs with the file name binary-tar.tar.gz which I renamed to ubuntu-server-12.06-armhf.tar.gz . If you want to skip that step, you can download ubuntu-server-12.06-armhf.tar.gz (180 MB).

Now we want to build the hardware packs for Mele A1000 using the server config in order to get as much as memory as possible for Linux. For this purpose, I’ve created a new config (mele-a1000-server) that disables video output in order to increase the memory available for Linux.

First install the scripts:


Then build the hardware packs:


You just find the hardware pack in a patch similar to bld_a10_hwpack_2012.06.21/mele-a1000-server_hwpack_2012.06.21.7z. Here’s the binary which you can also use for another server distribution.

Now you can create an SD card running Ubuntu Server as follows:


At this stage, you’ll need to a serial terminal to use the image, because eth0 is not enabled by default and sshd keys are missing. Let’s complete a few more step so that it can be used with the serial adapter.
Insert the SD card in Mele A1000, connect to the terminal via Putty / Minicom and once you get to the prompt, edit /etc/network/interfaces and add:


The other “issue” is that although sshd is running, it can’t be accessed because the keys haven’t been generated. Running those commands will generate the keys:


or simply run:


That’s all. We now have a (fully?) functional Ubuntu precise server running in Mele A1000 with 435 MB total memory, 106 MB used and 328 MB free:


[Update: It is possible to get the full 512MB memory for Linuxby adding “mem=512M” to extraargs in u-boot. The changes have been committed to github. Here’s the hardware pack for 512MB memory]

As promised at the beginning of the post, here’s the server SD card image (Nearly 1GB 121 MB*) that you can copy to an SD card using dd or Win32DiskImager. As long as you have a DHCP server running on your LAN, you should be able to login to the Mele A1000 via ssh using linaro user with the password linaro.

* After using the command


on the ext4 partition of the SD card, I managed to reduce the compressed size of the SD card image from ~1 GB to ~120 MB!

hey if the wifi, and gpu can be switched off in the kernel/fex it will make a great low power low cost replacement for my little plugs … hopefully running debian wheezy .. come on A1000 boards arrive at my house soon soon !!!

As i understand it as it stands the A1000 is pretty useless for anything meaty linux video wise until decent drivers are available .. prob. months away …

Is this platform really practical for a server? What kind of Iperf performance have you seen using ethernet?

It’s amazing no one has yet made a image that burns into the main device memory. A stage that will need to be crossed to gain speed increases.

@ Mark

The big pitfull is 32bit. No mainstream ARM chip yet 64bit.

A server running say PHP is nice to have 64bit integers for speed, constants and other computation reasons.

ARM wont be big in server fields until they are 64bit.

“To use this image, you’ll need to a serial terminal, because eth0 is not enabled by default.”

Other words you need a device connected to the USB? A UART Dongle some have made or been supplied by Mele reseller.

Others words if you don’t have an UART Dongle then don’t download this.

you can get these for $20 incl shipping from the guy on Aliexpress) from ebay … comes via HK post so far better than china post .. so in my case I paid GBP 1.78 (uk ebay) for the item plus cables incl shipping and it works perfectly (i ordered a couple extra at this price as spares 😉

Thanks for running those iperf benchmarks. It’s about what I expected. I briefly tested a gigabit USB->ethernet adapter on an A10 tablet and got even lower @ ~25 Mbit/sec.

How was the CPU usage during your tests? Was it maxed out?

I had to add explicit “mem” option to get all memory, otherwise it was using only 448M for some reason.

@ cnxsoft
Yes, I did it in kernel config, since I don’t know how to change cmdline in bootloader.

CONFIG_CMDLINE=”[email protected]
# CONFIG_CMDLINE_FROM_BOOTLOADER is not set
CONFIG_CMDLINE_EXTEND=y

AFAIK the upper 64M are reserved for MALI GPU, if it is disabled there should be no problem in using them. Still have to test it more extensively.

I found a way with sudo -su passwd to change the root password.

And now my next question. Is it possible that there no drivers for usb and/or sata in the Image?

I can’t see my Stick on the usb port and also not my FAT32 formatted Sata-HD in the doc.

I tried to install samba. It works but no drives where found.

Thanks in advance

I have similar experience (I waited 46 iterations).

It might be useful to completely disable drivers which need reserved memory (and related). Because now Mali reserves memory only implicitly (in boot parameter) and loading the driver is likely to crash the system. G2D seems to be quite broken, because it does not reserve memory at all, while it should take about 16M.

CONFIG_SUN4I_G2D
CONFIG_VIDEO_SUN4I_CEDAR
CONFIG_MALI
CONFIG_LYCHEE_LCD_SUN4I
CONFIG_LYCHEE_HDMI_SUN4I
CONFIG_SND_SUN4I_SOC_HDMIAUDIO

and all video-output related (maybe I missed some)

Ah, sorry I missed the custom kernel commit.

CONFIG_SND_SUN4I_SOC_HDMIAUDIO is hidden under CONFIG_SOUND and CONFIG_SND_SOC

It also might be a good idea to disable some android modules. I disabled these in my config (which is based on yours)
# CONFIG_ANDROID_BINDER_IPC is not set
# CONFIG_ANDROID_LOGGER is not set
# CONFIG_ANDROID_TIMED_OUTPUT is not set
# CONFIG_ANDROID_LOW_MEMORY_KILLER is not set

Especially ANDROID_LOW_MEMORY_KILLER is not something anyone would like to see on a server machine.

Module sw_ahci_platform.ko not loading automatically,
If you want the module SATA loading automatically then edit /etc/modules and at the sw_ahci_platform in a line.
But in this case does not always happen automount, and build a new kernel with built-in SATA module, now all ok.
Sorry for my english.

Hi there

I’m compiling myself a debian root kernel / fs and it works well. The only problem I have is that I can’t get the 512 MB ram (or maybe less) but I just end up with about 320 MB ram available.

Could you point out what exactely is needed to change?

hi,

i have a stable headless (not tested sata yet) debian wheezy armhf running now which i compiled from scratch and have only about 360MB total mem .. i have used my own armhf kernel/rootfs and boot.scr/script.bin

what do i need to modify to get 512MB RAM or as close to it as possible .. presumably i need to change whats selected/settings in the compilation process ?

thx

Hi,

I have the same question as mac me. Yet I would like to run X. Do you have a mele-a1000 config where 512MB are available? I tried to find the correct file yesterday but could not grep to the correct spot. Now I read you edited the server.config. HDMI would be a sweet thing. 🙂

Greetings, Frank

.. i read from the comments here where there was too’ing and fro’ing over kernel config changes and I wondered if there was a final kernel config fully optimised for the 512mb .. hence my qu.

.. i did try just just for fun adding the extra mem512MB uboot change but as expected it made no diff

.. i’ll have a try next at using the mele deb arm hf as a build machine to setup and build hopefully a 512 lean headless setup with the kernel config as guide

thx

The harddisk is moved back into the cover and connected to the Mele over the USB port.
So I can share via Samba.

When something new happens, I’ll try again.

Has there been anyone have experience? Or where there is a tutorial for it?

hi,

was there a resolution to the sata drive bug ? .. i have the same issue with an old 60GM toshiba 2.5″ that ive been using to test with … unless the mobo limits the power the drive gets (this drive is pretty low power) i cant see it being a power issue (usually if theres a power issue anyway the 2.5 inch drive no longer spins at full speed) .. ive swapped out the sata cable in the mele with 2 different known working ones and still the same error issues .. so maybe a driver issue ?

Stanislav Sinyagin

well, looks like it’s not only my machine that makes the problem.

every time I start from “mkdir dirforbld”, then “sudo lb build” is stuck in a forefer loop, with the last messages as follows:

All runlevel operations denied by policy
invoke-rc.d: policy-rc.d denied execution of stop.

then I do “sudo lb clean; sudo lb build”, and the procedure finishes successfully.

First thank you for this great build. It’s exactly that I was looking for.

I can’t get it to work on the Mele A2000. I put the SD card on the A2000, power on, and it don’t seem to work, at least it’s not making dhcp requests to the router. As I have no console access, I can’t do more. Is it possible that the Ethernet hardware is different on the A2000 than the A1000? I tried an ubuntu desktop build with VGA (made for the A1000), and it starts but says no ethernet.

Thanks in advance for any help.

Yes, I got a big file “ubuntu-precise-server-linaro-mele-a1000.bin” with 3.7 GB, transferred it to the 4 GB SD card with Win32DiskImager, and then tried to boot the A2000 with that card. The device don’t do anything, even the ethernet lights don’t blink, nor the router receives request.
This night I will try to redo the card with the makeSD script, that seems to be more precise than the disk imager.

I got from there the sun4i-spl.bin and u-boot.bin for the 1.7, but now I have a long road until I could rebuild it all. It seems so much tricky

I was thinking the same, but I don’t know what the offsets are. I tried to dd the new .bin files with the same offsets as stated in the a1x-media-create.sh script, that are:

sudo dd if=sun4i-spl.bin bs=1024 of=/dev/sdb seek=8
sudo dd if=u-boot.bin bs=1024 of=/dev/sdb seek=32

The result is that the device ignore the SD and boot on Android.

By the way, what serial cable/software do you recommend to obtain a terminal window on the PC? Is it RS-232 or USB?

http://rhombus-tech.net/allwinner_a10/a10_image/

This system boots perfect, except some details:
– It uses the HDMI output, and I would prefer the VGA (as my HDMI port is usually busy with the PS3 🙂
– The screen size is bigger than my TV, so I can’t see the menus on the desktop
– The network don’t work (not ethernet nor wifi) (major problem!!)

Any tips to hack the image and change this settings?

Thank you for the info.
My primary goal is still to use the server system described in this page. The VGA, screen size, etc. is secondary for me. The networking is the major issue.
I will try to merge both images, i.e. the boot section from the lucid image and the rest from the precise server image.
At least I will try it, before I receive the serial cable and proceed to the ugly hacks. 🙂

Finally I managed to boot this ubuntu server! Yeah!
I keep the image untouched and at some point it decided to boot and get IP. I don’t know why. I think that all the issue was that the system works only one of every 5 or 6 tries, so is some sort of random problem. It was confusing me.
I’ve done several reboots and it works (or doesn’t work) eventually.
I will do more tests when I have the serial cable.
Thanks for all the support.

I got the USB-UART bridge:

I connected it to the Mele and all I get is garbage characters. I think that I’m wrong with the settings. What are the right settings on speed/data bits/stop bits/parity/flow control?

Thanks!

I swap Tx and Rx and… voila!! I have now console access. Thank you very much for your help.

This server changes etherhet’s MAC address every reboot. My router changes the assigned IP and it’s a mess for me. How can I set up a static MAC?

I finally found how to set up MAC address in /etc/network/interfaces. No worry 🙂

is it possible to run linaro 13.02 on a10/a20?

according to this https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/LiveBuild
the steps described here to build the live system are outdated, but the allwinner is not in the list of supported hardware. thus it would be nice if you could update this article with instructions how to build a linaro 13.02 filesystem for a10/a20 – thanks

@Jean-Luc Aufranc (CNXSoft) thx, by adding several config files i managed to run linaro 13.02 (as i am running a headless server i did not installed the hardware pack), however the old way to build the base system was imho better as it was possible to select packages. using the prebuild system requires to uninstall stuff you dont want (like apache and mysql – running those apps on single core is no good idea…) and installing ssh-server (so serial connection is required) – i did not try the usual way to upgrade ubuntu to a higher version – does work… Read more »

ok, i will check the nano images next time

with upgrading i do not mean upgrading packages (apt-get upgrade) – i mean ‘do-release-upgrade’ – if this works with linaro it would be much easier instead of reinstalling. i have not tested this as i did not want to break my running system so it would be interesting if anybody tried this with this image or any other linaro systemn and performed a successful release upgrade

Hi. I’m planning to install a new Mele A2000 firmware to update android system. My question is: Installing a new firmware can break the loading of the Ubuntu system from SD?
Thanks

Many thanks. I was almost sure that it won’t break, but is good to confirm.
I have so many services running in the ubuntu server that I can’t live without it. The Mele A2000 is a rock and it’s running for years 24×7 without a faint. Wow!
