I use the revA dtb from the CoreELEC distribution.
Here is the file you asked dtb.img.gz (60.4 KB) .

Ray, can you let me know which iperf command you’d like me to run for testing RW over the Gb ethernet connection ?
I get this when using the GT-King as server:

wouldn’t it make sense to reformat the HDD with proper ext4 (I’m running CoreELEC exclusively)?
Yes, please try this speed test of the internal HDD:
Be sure test file is removed before and after speed test:
rm -rf /var/media/android/test.speed
Write speed test:
echo 3 > /proc/sys/vm/drop_caches
dd if=/dev/zero of=/var/media/android/test.speed bs=1M count=1024
Read test:
echo 3 > /proc/sys/vm/drop_caches
dd if=/var/media/android/test.speed of=/dev/null bs=1M
the HDD is a Hitachi HUS724040ALE641
the controller is an ASM1156-PM from ASMT
CoreELEC:~ # rm -rf /var/media/android/test.speed && echo 3 > /proc/sys/vm/drop_caches && dd if=/dev/zero of=/var/media/andro

the 271MB/s seems pretty high for such a HDD, I increased the amount of data written to get a better picture:

I also try the Netflix Add-on to check for temps, but I cannot find a way to select a fullHD stream, it stays at 960p max.
As for spotifyd, it just works !
I’m using the port from @jant90 available here : Release: Spotifyd addon for CoreELEC
I’m not sure about the dac stuff. I used the headphones jack located on the dac board, but the sound seems saturated 
On the other hand, the RCA outputs deliver a good sound

That’s slow. 17.3mbit/s?
If you can please create a samba share on the internal disk. Then try to transfer a big file from Windows using Gigabit Lan. I would like to know the speed.
I guess yes, but I would need another server for proper testing (I was using the GT-King for the iperf server).
If you have a laptop with Windows, linux or Mac then you don’t need another server. Iperf is not very reliable anyway
I’ve just tried the gs-king wlan and results are much better:

I also retried using the gb lan connection (with another server that the gt-king) and it worked better too.

Still not even close to gigabit
indeed.
Regarding the transfer speed using samba on the HDD, I have an average write speed of 40MB/s.
Writing back from the GS-King to my computer is slow
I’m wondering why the network speed varies over time so much.
That’s not good.
Well, this a pre-production sample with the very first version of the firmware. I informed bee-link about this issue, we’ll see what they can do about it. I also said that the leds were too bright when using the box next to the tv-set.
It seems that I’m not the only one to be annoyed by the brightness of the front leds:
http://www.bee-link.com/forum.php?mod=viewthread&tid=68677&extra=page%3D1
Decrease (or completely eliminate) a LED’s brightness is not a rocket science…
You can unplug it, put a resistor, paint it with black paint, cover with sticker, there are endless DIY solution.
My favorite method is the use of black insulator tape

For sure, but Bee-link can also change this on their side, or offer some options to change it, to avoid DIY on the user side. Don’t you think ?
My DIY solution involved a book
Just make the GS King some sunglasses.
