Add RK32XX: Pipo P4 – 4.4.4 Edition 2014/08/18 update
We’ve already got a long list of upcoming Rockchip RK3288 based Android media players, but no low cost development boards have been announced to date. We can certainly expect a Radxa Rock 2 board with the Cortex A17 processor, but it might not be the only one, as Firefly-RK3288 development board powered by Rockchip RK3288 is currently being developed by another Chinese team.

The developers told me it would be an open hardware project, but I’m not sure it will be 100% open source hardware, but at least they seem committed to release the hardware schematics, component’s placement file, and components’ datasheets. Hardware design and debugging have just been completed, and they have not reached the mass production stage just yet, which also means there’s no price information either. They will support Android 4.4 and Ubuntu for the board, and the SDKs, tutorial and hardware files will all be available from their website in August.
That website is not online yet (and I don’t even know the domain name), but the board can be found on oschina, and the development followed on TeeFirefly’s Twitter and Facebook accounts.
Rockchip RK3288 Specifications Released
Somebody working for a Chinese manufacturer informed me Rockchip RK3288 specifications have been released on rk3288.com. We’ve already known the application processor was based on a quad core Cortex A17 processor with a Mali-T76X GPU, but this website provides some more details which appears to have been taken from RK3288 technical reference manual. I can’t confirm the source nor the accuracy of the data, but I doubt somebody would have just put up something with detailed fake information.

The CPU frequency has not been mentioned, but earlier reports indicate the four Cortex A17 core should be clocked at up to 1.8 GHz. The GPU is allegedly Mali-T760 or T-764, the latter does not exist yet, or has not announced yet. However, numbers previously leaked showing 300 MTri/s triangle rate and 2.4Gpix/s fill rate conflict with the 1390Mtri/s, and 11.2Gpix/s listed on ARM Mali-T760 page. My guess is that Mali-T764 does exist, but it has not been announced, and provides a lower cost and performance alternative to Mali-T760. There’s new “article” about Mali-T764 by Enybox, one manufacturer of TV box and HDMI TV sticks.
There are some nice features from the specifications like LPAE support for up to 8 GB RAM, Gigabit Ethernet support, HDMI 2.0 for True 4K2K up to 60 Hz, 4K2K decoding, but the lack of support for SATA and USB 3.0 is a little disappointing.
Rockchip RK3288 Beta Firmware Release for Unnamed Android TV Box
The whole activity around the upcoming media players based on Rockchip RK3288 is pretty interesting, or some would say amusing. First, many companies started to release pictures of their boards a few months before their products are actually ready, and now we’ve got a beta Android 4.4 firmware for Rockchip RK3288 for an unknown TV box released viaGeekbuying Blog. I’ve read rumors about a Tronsmart Orion R28, so it might be that one, but who knows.
Before investigating the content of the firmware, here are the features that we know about the hardware:- Based on Rockchip RK3288 quad core Cortex A17 processor
- System Memory – 2GB RAM (Samsung)
- Storage – 8GB flash (Kingston)
- Wi-Fi - AP6330 Wi-fi module
The firmware is based on Linux 3.10, the build number is rk3288-eng 4.4.2 KOT49H eng.ant.20140721.164453 test-keys, and the software version RK3288_R_BOX_Android 4.4.2-SDK_v1.0.0_140613.
Most people won’t need this, but if developers want to checkout the content of the firmware, go ahead and download Geekbuying_RK3288 BETA__AP6330_20140721.zip.
After you unzip it, you’ll get a single Geekbuying_RK3288 BETA__AP6330_20140721.img file, which you might be able to extract with img_unpack and afptool utilities for RK3188 (TBC, I haven’t tried yet).
The firmware is for the device with:
- 2gb ram (samsung)
- 8gb rom(kingston)
- ap6330 wifi module
the kernel version is
- 3.10.0 ant@ubuntu01 #55 Mon Jul 21 15:51:46 cst 2014
