VideoStrong is better known for their Android set-top boxes with digital TV tuners, but they are making other hardware too, and their latest design is a Rockchip RK3399 development board named VS-RD-RK3399.

The company will offer support for both Android 7.1 and Linux, but when asked about the SDK I was told that “SDK could be down load from our indicating link”. If you are confused, so I was, but after deep mediation, I saw the light, and it probably means that they’ll provide download links for the SDK to their customers only.

The kit comes with an acrylic case, and antennas for WiFi and Bluetooth. I don’t have any confirmation about the price, but the board is listed on Alibaba for $149.99. We’ll soon find out more as the company intends to send a sample for review.

> System Memory – Dual channel DDR3-1866/DDR3L-1866/LPDDR3-1866/LPDDR4
Surely its only one of them and not a mix of all?
Does it have 4GB of RAM?
ı think any closed source code binaries makes this useless
according to the alibaba link : 4GB/32GB and dual channel LPDDR3-1866
They have yet another page with a few extra photos and details

@crashoverride
I used the specs in the doc file. No memory capacity, just supported memories.
But it looks like it’s 4GB LPDDR3-1866 as per other comments. You can probably ask them to put other memory type / capacities if the board supports it.
their site is down.
don’t even know if this “closed source binaries” made it useless, or hordes of open sourced fans. xD
As I have switched to Armbian from a companies effort for another product, I will avoid closed efforts now if possible.
Too much on this for a small development team
@Fossxplorer
4GB+32GB
and 2GB+16GB optional
Went to the Videostrong website.
The VS-RD-RK3399 webpage mentions RK3288 several times. And also Mali-T764 and Mali-T760.
Downloads section is empty.
And the Community/forum is in Chinese only.
I gave up.
What am I missing ?
@Robert
You’ll find a few more document @ https://www.cnx-software.com/2017/08/18/videostrong-vs-rd-rk3399-development-board-review-part-1-unboxing-kit-assembly-sdk-and-documentation/#vs-rd-rk3399-board-sdk-and-documentation
and a test of Debian @ https://www.cnx-software.com/2017/09/25/checking-out-debian-and-linux-sdk-for-videostrong-vs-rd-rk3399-board/
But AFAIK, there’s not really a community around that board, so you may have to rely on Firefly-RK3399. VS-RK3399 is probably better suited to companies with a specific project that work directly with VideoStrong.
@cnxsoft
Thanks for the links. I checked them out.
I was actually hoping to download source code of (patched) drivers to compile clfs and Arch Linux Arm.
I’m positive that I can get AOSP to compile (not all hardware is needed).
Is Mecool a Videostrong label, or maybe the other way around ?
I can’t find a Mecool website (only Gearbest), so I guess that it’s a Videostrong label.
You’re probably right though, that Videostrong is not targeting lone developers and tiny companies.
I’m probably better of with a Rock960 or a HiKey 960. The HiKey 960 is my first choice of all these boards. But no RJ45 Ethernet functionality on the HiKey 960 board still ticks me off. I would have to buy an adapter like the TP-Link UE300/UE330 to add wired local network and wired internet.
@cnxsoft
Forgot this. Firefly is ignoring me big time. I sent them a tweet that I’m not getting the email with verification code to register at their website : https://twitter.com/BobbyBabes/status/955463979811426304 But it received no response.
Then, 2 days ago, I sent them an email through their website’s contact form. Again no response.
Eight hours later, I also sent emails to the email addresses starting with sales@ and service@ at their “Contact Us” page. Again no response.
This doesn’t look good.
