will GTA04A5 have 512 MB or 1GB of RAM?
In shop, there is 512 MB stated, but on order tracking, there is a

"3. good news: we participated in the risk buy of Samsung 1GB RAM+512MB
NAND chips (as planned for the Neo900). So you will get 1 GB RAM and
faster NAND! Twice as much RAM as the GTA04A4 has. It has already been
tested by reworking a BeagleBoard XM and modifying the OS."

So, what amount of RAM will be soldered as PoP package?

> === Software ===
> First of all we already have a lot of software available:
> * boot system
> * kernel 3.7, kernel 3.12, ongoing kernel 4.3, 4.4-rc2 and later
> * Debian Wheezy / Jessie images (X11 w/o or with LXDE, XFCE or whatever you apt-get install)
> * Replicant for GTA04 with access to the F-Droid App-Store
> * QtMoko (may not run 100% on GTA04A5 because it needs adjustments)
> * whatever you like to install
> But we know from experience that especially the kernel is a very crucial component
> and if the kernel is buggy and does not get fixes and updates it can easily make the
> device practically unusable with sufficient reliability and operation time from battery.
> Therefore we have added a software development funds in the price.
> With this money we want to continue to work on kernel improvements, especially
> power management, and fixing significant bugs.
> Our ultimate goal is that this list becomes empty: <http://projects.goldelico.com/p/gta04-kernel/issues/>
> And remains empty because everything for the GTA04 can be found at kernel.org
> This is tough work and is not possible to get done by pure volunteers. Volunteers cherry-pick
> what they see the biggest fun and are happy if it works for them. They usually do not
> do the less funny bug fixes. Especially if they need a lot of tedious work (compile, test,
> fix cycle) or review by kernel maintainers is involved.
> Therefore we think it is the best way that you as the users of the hardware (and software)
> pay a little amount that we can use to hire freelancers and tell them what has to be fixed asap.
> Nevertheless, volunteer contributions are also very welcome.
> === Timing ===
> The shop has opened now and you can place your orders now.
> Production is expected to need 6-8 weeks but depends a little on delivery
> times of components and PCB production. And of course there are quite some
> upcoming holidays (X-Mas in 4 weeks, N-Y in 5 weeks, Chinese N-Y beinning of Feb).
> And, we have to test the devices and if anything is not working as expected, we have
> to repair. So please do not expect that we can ship before end of Feb 2016.
> === New Features ===
> The new features of the GTA04A5 (compared to GTA04A4) are mainly:
> * WL183x WLAN+BT module with 802.11a/b/g/n and BT4/BLE
> * the GPS receiver can provide a 1 second impulse interrupt to the CPU
> * the (different) infrared receiver can be independently powered off to save some more mA (it was alternatively powered with RS232 before) 
> * some sensors have been upgraded to non-obsolete versions (e.g. BMA180 is out of production)
> * WLAN/BT power controlled through a GPIO (so that VAUX4 is now free for other use)
> * 10-pin FFC connector for external keyboard or other I2C devices
> * the GPS antenna switch has been redesigned to switch more reliable
> * improved headset detection hardware (GPIO instead of ADC)
> * CPU will be always 1 GHz and Memory 512MB RAM / 1GB NAND
> We will update the GTA04 manual to describe everything. Final Schematics will
> also become available (this time as searchable PDF).
> So again here is the link to the shop:	<http://shop.goldelico.com/wiki.php?page=GTA04>
> Thats it. Did I forget anything important? If yes, please ask.
> Finally, I would like to say thank you for your patience with this long-running project.
> BR,
