Rockchip RK6321 Dual Core Cortex A5 SoC Targets Wearables with WiFi, Bluetooth, 3G and GPS

Rockchip and Intel started to work on a platform called XMM6321 last year. It featured a dual Core Cortex A5 processor, 3G connectivity, WiFi, and GPS, which was aimed at entry level 3G smartphones and tablets. Fast forward to 2015, Rockchip showcased their RK6321 processor at the Hong Kong Electronics Fair, with very similar specifications compared to XMM6321, but instead it targets wearables such as smartwatches, or children and elderly tracker. So I’ m not quite sure whether Intel XMM6321 and Rockchip RK6321 are the same processor with a different name, or Rochchip tweaked RK6321 specifically for wearables. Key features of Rockchip RK6321 processor: CPU – Two Cortex A5 cores up to 1GHz with 32KB L1 D-cache, 32KB L1 I-cache, and 512KB L2 cache GPU – Supports OpenGL ES 2.0 Memory and Storage I/F – 16-bit LP-DDR2 SDRAM, 8-bit  eMMC, 16-bit NAND Display I/F – MIPI DSI up to FWVGA […]

Linux 4.2 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.2 last Sunday: So judging by how little happened this week, it wouldn’t have been a mistake to release 4.2 last week after all, but hey, there’s certainly a few fixes here, and it’s not like delaying 4.2 for a week should have caused any problems either. So here it is, and the merge window for 4.3 is now open. I already have a few pending early pull requests, but as usual I’ll start processing them tomorrow and give the release some time to actually sit. The shortlog from rc8 is tiny, and appended. The patch is pretty tiny too. Go get it, Linus Some notable changes made to Linux 4.2 include: File systems New features for F2FS including per file encryption CIFS support SMB 3.1.1 (experimental) Cryptography – Jitter Entropy Random Number Generator, Chacha20 stream cipher and Poly1305 authentication (RFC7539),New RSA implementation.

Rockchip’s Light Work OS Makes Android Look Like Windows

Android is not exactly great to use as a desktop PC, so there’s been various attempts to improve this for Android boxes, tablets, and laptops for example with Remix OS, bringing a more desktop-like user experience. Rockchip showcased multi-window supports in some tablets a while ago, and now they have “Light Work OS”,  an operating system based on Android 5.1 that feature a start menu and multiple windows support. PiPo even decided to use a background image with Windows logo in their PiPo X9 tablet powered by Rockchip RK3288. The problem with Android used as a mini PC goes much further than the lack start menu or window mode, but copy/paste can be a pain, and things you take for granted on desktop, simply may not be available in Android apps: some graphics elements may not be clickable, some website features may not work properly (I’m thinking WordPress editing here..), […]

Rockchip RK3288 vs RK3368 Benchmarks Comparison

Rockchip RK3368 TV boxes are now shipping, and I’ve just reviewed Beelink i68, so it’s a good time to compare the latest octa-core Cortex A53 processor with its predecessor, RK3288, featuring four ARM Cortex A17 cores, as well as a Mali-T764 GPU. To compare both processors, I’ve used Antutu 5.x, Vellamo 3.x and 3DMark Ice Storm Extreme benchmarks results for Beelink i68 (RK3368) and Tronsmart Orion R28 (RK3288). The ratio divides the scores, and a ratio greater than 1 indicates RK3368 outperforms RK3288. Rockchip RK3288 Rockchip RK3368 Ratio CPU Quad core Cortex A17 @ 1.8 GHz Octa core Cortex A53 @ 1.2GHz GPU ARM Mali-T764 PowerVR G6110 Antutu 5.x Overall 36865 34171 0.93 Multitask 5753 4041 0.70 Runtime 1976 2949 1.49 RAM Ops 2475 2346 0.95 RAM Speed 3153 2601 0.82 CPU Integer (multi-thread) 2433 2973 1.22 CPU float-point (multi-thread) 3565 2930 0.82 CPU Integer (single thread) 1432 1536 1.07 […]

Kodi 14.2 Linux Ported to Rockchip RK3288 with VPU Hardware Decoding

Rockchip RK3288 is one of the most popular platforms for TV boxes, and while most boxes are sold with Android OS, it can also run various Linux distributions with two main caveats: 2D/3D GPU acceleration, and hardware video decoding by the VPU. It appears the last two have been worked on, as yesterday, I got tipped that Kodi 14.2 Linux was running on Ugoos UT3 and Radxa Rock2 Square. Since both hardware platforms showcased a Kodi port at the about same time, it’s probably safe to assume they use the same implementation (despite slightly different build dates May 29 vs June 6), which has been developed by “Marc” (or is it MAC?) using the Android libraries and libhybris for video decoding, raw2 device driver for 2D HW accelerated blitting and converting frames, and ARM OpenGL library, driver and examples, among other software packages. So let’s check the demos starting with […]

Arch Linux ARM Can Now Be Installed on Rockchip Based Hisense Chromebook

Hisense Chromebook C11 is one of the $149 Chromebooks powered by Rockchip RK3288 processor recently launched. So far, I could not find instructions to install any Linux desktop distributions on this type of platform, but now Hisense Chromebook (codename: veyron_jerry) appears to be the first Rockchip platform officially supported by Arch Linux ARM (ALARM). Hardware video decoding won’t work, 3D graphics acceleration is most probably not working either, and it’s not clear if all hardware parts are supported, and the built-in wireless module is said to break under high throughput, so a USB WiFi dongle or Ethernet adapter is recommended instead. But at least if you follow the installation instructions, you won’t modify your Chrome OS installation on the eMMC flash, as Arch Linux ARM will boot from external storage, either from an SD card or a USB flash drive, so it should be completely safe to try it out.

Rockchip RKi6000 WiFi SoC Promises Bluetooth 4.0 Power Consumption Levels

Rockchip has announced a new WiFi SoC for IoT applications claiming 85% lower power consumption compared to competing WiFi solutions, which allows cell-coin battery powered WiFi systems thanks to a power consumption equivalent to what you’d get with a Bluetooth 4.0 LE system. Rockchip RKi6000 is said to consume 20 mA (@ 3.3V) during Rx operations. The SoC has been developed with an unnamed third party, and can achieve a lower power consumption thanks to three improvements: Improvement of RF transceiver architecture. The architecture can greatly reduce the active power consumption of IoT smart devices during continuous data transfer. Ultra low power can be achieved both in work and standby mode. Dozens of international patents have been filed for this technology. Adaptive dynamic power control technology. Power efficiency is optimized in different working modes and the total power consumption is reduced greatly in different application scenarios by adjusting the chip’s power […]
