Official Rockchip Github Account and Wiki Launched

Following the popularity of RK3066 and RK3188 processors in 2013, a community of developers for Rockchip Linux and Android development was created with corresponding linux-rockchip github account, mailing list and #linux-rockchip IRC channel, and now most of the information can be gathered from development board manufacturers like Firefly. However, I’ve just been pointed out to some VA-API driver for Rockchip RK32xx processor, on rockchip-linux (not linux-rockhip) github account, with the following tagline: An open source software for Rockchip SoCs, This site maintained by Rockchip The only person currently registered to this account, Jacob Chen (陈豪), is a software engineer working for Rockchip, so it does indeed look to be official. The github account also links to rockchip.wikidot.com with links to communication channels established by linux-rockchip community, and lots of entries about Linux, Android, U-boot, and so on, most of which are currently placeholders. So it still looks like work in […]

Xiaomi Mi Box 3 Enhanced / Pro (Mediatek MT8693) Benchmarks and System Info

Xiaomi Mi Box 3 Enhanced is the first TV Box I’ve tested with a processor featuring ARM Cortex A72 cores, so I’m very eager to see how its performs, and I’m expecting it to be quite faster than Rockchip RK3288, but still not quite matching Nvidia Tegra X1 processor found in Nvidia Shield Android TV box. But first let’s check the system information with CPU-Z app. First, it looks like CPU-Z does not detect big.LITTLE processor very well, as it detect a six core ARM Cortex-A72, instead of a six core processor with two Cortex A72, and four Cortex A53 cores. The clock speed ranges between 507 MHz and 1.57 GHz, but that’s likely the number for the Cortex A53 core, as the marketing materials report the Cortex A53 cores run at up to 1.6 GHz, and the Cortex A72 cores up to 2.0 GHz. Antutu info reports the frequency […]

Rockchip PX3 and PX4 Processors Are Designed for Automotive Infotainment & Dashboards

Rockchip PX2 processor, similar to Rockchip RK3066 but targeting industrial and automotive applications, was launched in 2014. Rockchip now has at least two new member in their PX family with PX3 and PX4 specifically designed for automotive infotainment and car dashboards thanks to dual display support, at least according to one article on Elezine. Rockchip PX3 is definitely confirmed with its own page on Rockchip website, and features a quad core Cortex A9 @ 1.4 GHz with a Mali-400MP4 GPU, and while there’s no info about PX4 yet on the company website, the SoC should come with a quad core Cortex A53 processor @ 1.3 GHz with a Mali-T722 GPU, as well as HDMI 2.0 video output, and H.265 video decoding. The article also lists 7 key function of Rockchip solutions: “Quick startup and fast revert track” Navigation system with free updates HD video recording (car DVR) Advanced ADAS algorithm […]

Rockchip RK3229 based MXQ 4K System Info and Antutu Benchmark

Since MXQ-4K TV box is not working well enough, even after a firmware update, I’ve decided not to do a full review. But since this is the first Rockchip RK3229 device I’ve received, I’ll still share some system information (CPU-Z) and Antutu benchmark results. Rorkchip RK3229 is detected as a quad core Cortex A7 processor between 408 MHz and 1.46 GHz with a Mali-400MP GPU. CPU-Z does not know about it, so it only detect RK3066, meaning the manufacturing process (40 nm) is wrongly reported, and RK3229 is manufactured using a 28nm process. The model us MXQ-4K (rk322x) with the board simply called rk30sdk. They’ve also set the framebuffer resolution to 1280×720 probably due to the limited performance of Mali-400MP GPU. Internal storage is shown to be 3.81GB large, but that’s because I modified the firmware, and it’s now 1.44GB with the latest firmware. Rockchip RK3229 does not support Android […]

MXQ-4K RK3229 TV Box Firmware Update – March 8, 2016

MXQ-4K is one of the first TV boxes based on Rockchip RK3229 processor, and while it promised a lot with regards to high bitrate 4K H.265, H.264 and VP9 videos, it failed it deliver when I tested some videos from a USB hard drive, and its Antutu score varies from 12,000 to 19,000 depending on the ambient temperature…  The company has now released a new firmware, albeit without any changelog. The build number is rk322x-eng 4.4.4 KTU84Q eng.hotack.2016.03.08.102208 test-keys meaning it was build on March 8, 2016. There are about three apps for OTA firmware update in the January firmware, but none of them worked, so I had to update firmware using the “USB OTG” method, meaning all your settings and apps will be wiped out, so if you don’t have a backup, be prepare to re-install everything. So first, you’ll need to download the firmware (MXQ-4K_ota_20160308.zip), and extract it. […]

Linux 4.5 Released – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.5 on Sunday: So this is later on a Sunday than my usual schedule, because I just couldn’t make up my mind whether I should do another rc8 or not, and kept just waffling about it. In the end, I obviously decided not to,but it could have gone either way. We did have one nasty regression that got fixed yesterday, and the networking pull early in the week was larger than I would have wished for. But the block  layer should be all good now, and David went through all his networking commits an extra time just to make me feel comfy about it, so in the end I didn’t see any point to making the release cycle any longer than usual. And on the whole, everything here is pretty small. The diffstat looks a bit larger for an xfs fix, because that fix has […]

How to Resize Partitions and Update Firmware in MXQ-4K TV Box (Rockchip RK3229)

Since I’ve received MXQ-4K Android TV box yesterday, I have started to play with it, and so far I can’t say I’m impressed, as while the device automatically detected the maximum resolution (3840×2160 @ 60 Hz) for my television, I could not play any of my 4K samples smoothly with either the pre-installed Kodi 15.2, Video and Video Player apps, there’s no power off mode (only standby), and the “internal partition” is only 0.96GB large which can quickly become an issue if you plan on installing several apps. Since GeekBuying has released the stock firmware, I decided to try to adapt the method to resize the partitions for GeekBox (RK3368) to MXQ-4K. Rockchip RK3229 Firmware Modding I’ve used a computer running Ubuntu 14.04, and assume you have most tools pre-installed. The first step is to download the firmware (MXQ-4K_ota_ok_20160127.img update.img), and install the tools to extract it :
