I’ve already measured power consumption running Antutu and playing a 4K video on Rockchip RK3288 and Amlogic S812 platform, as described in “Power Consumption of Amlogic S812 and Rockchip RK3288 TV Boxes“, and now that I have an Intel Bay Trail-T mini PC running Android 4.4 with Wintel W8, I was interested in comparing its power consumption to the ARM platform. [Update: I forgot to mention measurements have all been done @ ~5V.] The test normally consists in several steps: Boot the device Run the latest Antutu benchmark Connect a USB hard drive Play a 4K video in Kodi from the hard drive Diconnect the hard drive Power off the device But since the current draw was a little to high at times, I got a few issues with my setup. First, I had to boot twice hence the “Power On 1” and “Power On 2” strings on the chart, […]
Linux 4.0 Release – Main Changes, ARM and MIPS Architectures
Linus Torvalds “Ima Sheep” released Linux Kernel 4.0 on Sunday: So I decided to release 4.0 as per the normal schedule, because there really weren’t any known issues, and while I’ll be traveling during the end of the upcoming week due to a college visit, I’m hoping that won’t affect the merge window very much. We’ll see. Linux 4.0 was a pretty small release both in linux-next and in final size, although obviously “small” is all relative. It’s still over 10k non-merge commits. But we’ve definitely had bigger releases (and judging by linux-next v4.1 is going to be one of the bigger ones). Which is all good. It definitely matches the “v4.0 is supposed to be a_stable_ release”, and very much not about new experimental features etc. I’m personally so much happier with time-based releases than the bad old days when we had feature-based releases. That said, there’s a few […]
Open Hour Chameleon RK3288 TV Box Gets (Partial) DTS-HD and Dolby TrueHD HDMI Pass-through Support
People owning AV receivers capable of outputting 7.1 channels or more have had a hard time finding Android TV boxes that supports HD audio pass-through via HDMI. Many devices can pass through 5.1 codec like DTS or Dolby Digital (AC3 / E-AC3), but so far, none of the boxes I’ve tried could manage content with DTS-HD (MA / HR) and Dolby TrueHD with 8 channels properly. The one that came close was Zidoo X9 with support for Dolby TrueHD 5.1 and 7.1, but it downmixes 7.1 channels to 5.1 channels. So the only cost effective options to get proper 7.1 channel pass-through were Intel based mini PCs running Linux such as Asus Chromebox M004U or Intel NUCs. But recently, I’ve seen some progress. For example, yesterday Cloud Media released a new firmware for their Open Hour Chameleon media player based on Rockchip RK3288 processor. Their Android 4.4.2 firmware (version 1.0.23) […]
Asus Chromebit Chrome OS TV Stick to Sell for Less than $100
Google has just announced Rockchip RK3288 Chromebooks, and also quickly mentioned Chrombit Chrome OS dongle, but with very few details. However, several large US blogs like Engadget and Gizmodo got a sample (mock-up?), and shared more details. So now we have the technical specifications of the dongle, which unsurprisingly also feature RK3288 processor: SoC – Rockchip RK3288-C quad core Cortex A17 processor with ARM Mali-T764 GPU. System Memory – 2 GB DDR3L SDRAM Storage – 16 GB eMMC Flash Storage Video Output – HDMI Connectivity – Dual band Wi-Fi 802.11 2×2 (MIMO) a/b/g/n/ac, Bluetooth 4.0 USB – 1x USB 2.0 host port, 1x micro USB OTG port Power – 5V via micro USB port Dimensions – N/A Weight – N/A It’s quite likely the Rockchip processor won’t run at full speed, at least not for a long period of time, as it’s likely to overheat in such small form factor, […]
$149 Rockchip RK3288 Chromebooks by Haier and HiSense Launched
Just ten days ago, Asus C201 Chromebook powered by Rockchip RK3288 processor was spotted on a product catalog. Today, Google unveiled two Rockchip Chromebooks, except the Asus Chromebook is not there yet, but instead Haier Chromebook 11 HR-116R and Hisense Chromebook both available for pre-order for $149 respectively on Amazon US and Walmart. Both laptops have very similar specifications: SoC – Rockchip RK3288-C quad core Cortex A17 processor @ 1.8 GHz with ARM Mali-T764 GPU. (Wallmart claims a 2.5GHZ processor frequency, but this has to be an error). System Memory – 2 GB DDR3L SDRAM Storage – 16 GB eMMC Flash Storage + micro SD slot + 100GB Google drive storage, free for 2 years Display – 11.6” HD wide screen LED-backlit display; 1366 x 768 resolution Video Output – HDMI Audio – HDMI, stereo speakers, headphone jack, Connectivity – Dual band Wi-Fi 802.11 2×2 (MIMO) a/b/g/n/ac, Bluetooth 4.0 USB […]
Radxa Rock 2 Square Beta is Now Available for $99 (In Limited Quantities)
Radxa Rock 2 Square is the low cost version of Radxa Rock 2 Full development board. Both board are based on Rockchip RK3288 quad core Cortex A17 processor, but the former has not quite as many features as the full version. The good news is that about 90 samples of Rock2 Square Beta can now be purchased for $129, with the price dropping to $99 with ROCK2^2BETA coupon (to be used after login to Paypal). The price include a Radxa RK3288 system-on-module with 2GB RAM and 16 GB eMMC, but a 4GB/32GB version is also planned for later. Rock2 Square board specifications: Processor/Memory/Storage – Via Rock2 SoM including Rockchip RK3288 quad core Cortex A17 processor, 2 to 4 GB RAM, and 16 to 32 GB eMMC. External Storage – SATA and micro SD slot Video Output – HDMI 2.0, LVDS connector Audio I/O – HDMI, headphone jack, built-in microphone, and […]
Radxa Rock 2 Square is a Rockchip RK3288 Development Board for Hobbyists
When Radxa Rock 2 was first unveiled, it became clear it was not aimed at the hobbyist market, as it includes lot of features such as SATA, 3G modem, dual Gigabit Ethernet, up to 4GB memory and so on, and is likely to cost a few hundred dollars. The company is now working a cheaper baseboard called Radxa Rock 2 Square leveraging the same Radxa Rock 2 SoM used with the full-featured baseboard (now also called Radxa Rock 2 Full), but with less features and at price point that should be more affordable to individuals. Preliminary Rock 2 square specifications (derived from picture above): Processor/Memory/Storage – Via Rock2 SoM including Rockchip RK3288 quad core Cortex A17 processor, 2 to 4 GB RAM, and 16GB eMMC. External Storage – SATA and micro SD slot Video Output – HDMI, LVDS connector Audio I/O – HDMI, headphone jack, built-in microphone, and optical S/PDIF […]
Asus C201 Chromebook to be Powered by Rockchip RK3288 Processor
If you’ve been following this blog, you should know that Rockchip is working with Google on Chrome OS, so it was just a matter of time before a Rockchip powered Chromebook or Chromebox sees the light of the day. The first Rockchip RK3288 chromebook might end up being Asus C201 Chromebook with apparently a custom version of the Cortex A17 processor dubbed Rk3288-C, as OMG Chrome found out in Troxell’s 2015 brochure for K-12 education. So far we only know a few details about the specifications: SoC – Rockchip RK3288-C quad core Cortex A17 processor @ up to 1.8GHz System Memory – 2 to 4 GB DDR3 Storage – 16GB eMMC Display – 11.6″ display with 1366×768 resolution Webcam – VGA resolution The exact model name should be C201PA. Rockchip RK3288 should provide performance quite similar, and in some cases even better, to Intel Atom Z3735F, except possible when it comes […]
