Repo is : deb http://packages.efikamx.info/ maverick main universe

This is a signed repository which could be add in /etc/apt/sources.list after adding the genesi key like [[http://blog.efikamx.info/2011/03/maverick-installer-march-2011-package.html|that]]:

== Linaro ==

Linaro is a not-for-profit (NFP) engineering organization that works on Linux-based open source software and tools.
It provides aligned engineering and investment in upstream open source projects, a six monthly release of tools and software and support to silicon companies in upstreaming their system-on-a-chip (SoC) support.

Linaro is [http://blog.efikamx.info/2010_11_01_archive.html also working on the efika] but the support is not finished.

Tools form Linaro (such as kernel / toolchain )could be found here :

== Open the smartbook (and boot from SD) ==

http://www.genesi-usa.com/support/smartbook/tutorial/keyboard

Here are some instructing found on IRC.

Don't use knife, use a needle or so ... might work

- there are four small holes on the top of the keyboard
- put a tiny screwdriver in them and slowly remove the keyboard (pull it towards you carefully)
- also, when you manage to get the top side loose, be careful not to rip off the foilcable connecting the keyboard to the mobo
- when you manage, you will find the switch part (four switches on a single part) ... invert what's on them
- then you can boot from full-size SD card (NOT NEEDED ANYMORE ! use uboot update)

Switch are
1. mmc0 2. mmc1 3.pata 4. no_avaible

== Uboot-update ==
Before doing that, you should really know what you are doing!

Moreover, Genesi team prefer that you do **not** touch your firmware as you can easily break your device

<pre>
[00:25] <Neko> this is why we don't give out the u-boot source code
[00:25] <Neko> the SD card will *NEVER* load again on Smartbook
[00:25] <Neko> it has a "power off" command in it
</pre>

<pre>
[00:32] <Neko> the uImage on the card is specifically engineered to boot and flash the Smarttop, because this is the only file the old Smarttop U-Boot will load
[00:32] <Neko> the Smartbookk will load the boot.scr
[00:33] <Neko> once they are both flashed to new U-Boot they both load the boot.scr and therefore the uImage is ignored
[00:34] <Neko> okay, take the card
[00:34] <Neko> flash the original SD image over it
[00:34] <Neko> check if it has a space of 8MB or so before the first partition
[00:34] <Neko> if not, copy the files off
[00:34] <Neko> repartition it with 8MB offset
[00:34] <Neko> copy the files back on to a vfat partition
[00:35] <Neko> (it has to be >64MB)
[00:35] <Neko> then dd if=u-boot-2009.01-2.0.6-efikasb of=/dev/mmcblk0 bs=1024 skip=1 seek=1
[00:35] <Neko> pop the keyboard, reverse all dip switches
[00:35] <Neko> use the SD card to boot the firmware and hit the key to go into the prompt
[00:36] <Neko> you will find, by referencing the boot.scr on another machine, exactly how to load and flash the SB firmware
[00:36] <Neko> do it by hand
[00:36] <Neko> then, once you are done *wipe that damn SD card* and flip your DIP switches back when you are sure it has nothing but 0's on it :D

...

[01:26] <Neko> because the best way to get access to the u-boot file is from that vfat partition
[01:26] <Neko> your layout should be
[01:26] <Neko> MBR | 8MB free space | VFAT partition
[01:26] <Neko> the MBR is 512 bytes and the iMX boot ROM padding is 1024 bytes
[01:26] <Neko> seek=1 skip=1 will jump over the MBR and the padding in the U-Boot file, placing 160kb of data in that 8MB space
[01:27] <Neko> since the NOR is 8MB and U-Boot may expect that much space there.. it's safer to have that much space on the SD before the first partition
[01:27] <Neko> anyway you can read it with mmcinit; mmcprobe 1; fatload mmc 0:1 ${loadaddr} ubootsb.bin or whatever it is
[01:30] <Neko> hmm, checking boot switches..
[01:30] <Neko> 3 needs to be off
[01:31] <Neko> 2 needs to be off
[01:31] <Neko> 1 needs to be off
[01:31] <Neko> 4 needs to be on...
[01:31] <Neko> or off.. depending on chipselect for SD card slot
[01:32] <Neko> so (off off off [SD]) and (on on on off) as nor is active low
[01:32] <Neko> otherwise you are trying to boot from the PMIC :]
[01:33] <Neko> that's right from the schematic, it should work
</pre>

<pre>
[00:47] <Marex> zumbi_: you don't need that (JTAG) to test either mainline uboot or mainline kernel :)
[00:47] <zumbi_> Marex: well, at least i need to recover the functionality to boot from SD
[00:48] <Marex> zumbi_: just select the right switches :)
[00:48] <Marex> then write the mainline uboot with this command:
[00:48] <Marex> dd if=u-boot.imx of=/dev/mmcblk0 bs=1024 seek=1
[00:48] <Marex> to the card ... and boot :)

== OOo4kid ==
By Ericb2

untar it, and after, cd en-US/ooo4kids1.2/program and launch it : ./soffice

http://ftp.educoo.org/home/OOo4Kids/Linux_ARM/smartbook_efika/en-US/

== Drivers ==

2d,3d, xv acceleration all require binary blobs, there is a fbdev driver which is quite fast and free, but doesn't offer xv accel

== Kernel ==

Neko and steev and rtp do lots of kernel work

Some information about the last kernel could be found [http://www.powerdeveloper.org/forums/viewtopic.php?f=2&t=2696 on the forum]

more informations [[Efika mx kernel|here]]

== Memory Usage ==

The free command rapport "only" 400mo of Ram on 512, why ?

In actual fact what we reserve is 32MB for the IPU (which is the thing that handles the display) and 32MB for *both* GPUs. We are looking at revising these values, but it will stay around ~64MB.
== 2D/3D ==

http://www.powerdeveloper.org/forums/viewtopic.php?t=1944

== Gentoo ==
Steev did some doc about installing Gentoo on the MX

[http://dev.gentoo.org/~steev/efika/arm/install.xml Steev's page]

== Fedora ==

There's a Fedora image at https://fedoraproject.org/wiki/Architectures/ARM/F18/Remixes/Genesi_Smartbook?rd=Architectures/ARM/Genesi_Smartbook with a recent kernel release and uses Barebox http://wiki.barebox.org/doku.php?id=boards:efikasb

== Arm hardfp ==

Check with zumbi and Markos
<code>
easy to test: debootstrap --foreign --arch=armhf http://ftp.debian-ports.org/debian/
</code>

* Debian with kernel 3.8 thanks to markos: http://www.freevec.org/content/efikamx_updated_wheezy_and_jessie_images_available

== Change SSD ==

<pre>
(02:57:56 PM) Sleep_Walker: is it posible to attach (somehow easily) PATA HDD instead of SSD?
(02:58:37 PM) Sleep_Walker: I don't have my efika opened yet and I can't see this info on google
(02:58:44 PM) Sleep_Walker: Marex: btw. hi ;)
(02:59:09 PM) markos_: Sleep_Walker, nope, but in the smarttop you could replace the internal pata one with a bigger one -but they're expensive
(02:59:48 PM) Sleep_Walker: it's not some common connector? like 2.5" HDD?
(03:01:20 PM) markos_: no, it's an ssd chip with a small pata connector, wait
(03:03:43 PM) markos_: the smarttop uses this: http://www.getpartsonline.com/sdpa3cd-032g.html (well the 16GB version anyway)
(03:03:53 PM) markos_: $49 wow, that's cheap
(03:05:31 PM) Sleep_Walker: nevermind, I'll use NFS/NBD/iSCSI instead
(03:05:39 PM) Sleep_Walker: thanks for answer :)
(03:06:05 PM) markos_: er, wrong, the smarttop uses 8GB
(03:06:21 PM) NekoXP [~matt@cpe-67-11-135-209.satx.res.rr.com] entered the room.
(03:06:58 PM) markos_: and $99 for the 64GB version here, nice http://www.cpi-inc.biz/servlet/the-1428/SANDISK-64GB-LIF-SOLID/Detail
(03:07:03 PM) markos_: I'm tempted
(03:07:21 PM) Sleep_Walker: I hope that next version will use some standard connector
(03:08:00 PM) markos_: it's a PATA SSD module, used a lot in industrial embedded applications
