Getting Started with B&T RTL-00 RTL8710 Module – Serial Console, AT Commands, and ESP8266 Pin-to-Pin Compatibility

The announcement of the ultra-low cost ARM based Realtek RTL8710 WiFi modules for IoT applications generated quite a lot of buzz since they can potentially compete with the popular ESP8266 modules. The main problem at the time was documentation and software support, but after some searches we could find that RTL8710 was part of Realtek Ameba family, and found some documents and an SDK for RTL8710/RTL8711/RTL8195. ICStation also kindly provided one B&T RTL-00 module for review, which costs $3.55 shipped per unit, and as low as $2.85 if you purchase 10 or more. The question here is how to get started? The answer can be found in page 8 of the Chinese datasheet for the module with GB0 and GB1 pins used for Tx and Rx to access the serial console. Time for some soldering… For the first test, we’ll just need Tx (GB1), Rx (GB0), GND and 3.3V, and […]

M12N Amlogic S912 TV Box Benchmarks

Since Shenzhen Shiningworth MXQ Plus M12N is my first TV box powered by Amlogic S912 octa-core processor, I’ve decided to write a separate post to show system information with CPU-Z, and benchmark results with Antutu 6.x, Vellamo 3.x, and 3Dmark Ice Storm Extreme. Please note that it may not be representative of all Amlogic S912 boards, as mentioned in the teardown post, there are some concerns about the thermal design of M12N TV box. M12N / Amlogic S912 System Info I’ve merged CPU-Z’ SOC, DEVICE and SYSTEM data into a single table. The app correctly detects an 8 core Cortex A53 processor @ 100 MHz to 2.02 GHz with an ARM Mali-T820 GPU. The brand for this particurlar device is MXQ, and Model m12n. Frame buffer resolution is 1920×1080, and memory and storage data are both OK for a box with 2GB and 16GB flash. The device runs Android 6.0.1 […]

How-to Setup a DLNA/UPnP Server in Linux for Smoother Video Streaming with Kodi and Other Media Players

I’m normally playing videos from a SAMBA share installed in a Ubuntu PC to play files from Kodi in Android TV box reviews, but sometimes when I use 10/100 Ethernet, or worse WiFi local “streaming” may not be as smooth as possible. SAMBA is convenient because of access control and read write operations, but if you want to get a bit more performance, you may switch to NFS instead, or like I’ve going to show you here to a DLNA / UPnP server to stream videos locally from Kodi 16.1. There are several options, but MiniDLNA is lightweight compared to MediaTomb, so it will also run on lower end hardware like cheap ARM Linux development boards like Raspberry Pi, Orange Pi, or NanoPi NEO without taking too many resources. Installation is very easy in Debian / Ubuntu distributions, and I supposed this should also work with Windows Subsystem for Linux […]

4K VP9, H.265 and H.264 Video Playback in Amlogic S912 M12N TV Box

I’ve received my first Amlogic S912 TV box with MXQ Plus M12N TV box this week-end, and I’ve decided to start testing by showing the media capabilities of the platform that is supposed to support 4K VP9 up to 60Hz, 4K 10-bit H.265 up to 60Hz and 4K H.264 up to 30 Hz. I connected the device to Onkyo TX-NR636 A/V recevier itself connected to  LG 42UB820T 4K UHD TV, set video output to 2160p @ 60Hz, and played several 4K video samples from a USB hard drive using the pre-installed version of Kodi 16.1: 4K Hawaii Sunset _ GoPro Hero 4 Black [email protected] (Downloaded from YouTube) – OK Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265 @ 30 fps – No audio) – OK big_buck_bunny_4k_H264_30fps.mp4 (H.264 @ 30 fps – MPEG1/2 and AC3 audio) – OK big_buck_bunny_4k_H264_60fps.mp4 (H.264 @ 60 fps – MPEG1/2 and AC3 audio) – Video a bit choppy, large audio delay.

GOLE1 mini PC Tablet Review – Part 2: Android 5.1 and Windows 10

GOLE1, also called GOLE1 F1, is an interesting device because it’s quite difficult, it’s like the offspring of a mini PC and a tablet with a smallish  phone-like 5″ capacitive touch screen. It also dual boot Windows 10 and Android 5.1. I’ve already discussed about the hardware, and taken picture of the device, accessories, and motherboard, in the first part of the review, so today I’ll report my experiences with Windows 10 and Android 5.1, as well as the potential use cases. Since I’ve already reviewed Intel Atom x5-Z8300 mini PCs, as well as a dual boot Windows and Android Intel mini PC, I’ll focus on what makes GOLE1 different in this review. GOLE1 Dual Boot and Use Cases I normally check my emails on my smartphone while having breakfast in the morning, but one day the charging micro USB cable was not connected properly to my phone, so I […]

MXQ Plus M12N (Amlogic S912) TV Box Review – Part 1: Specs, Unboxing, and Teardown

Shenzhen Shiningworth has just sent me the first Amlogic S912 Android TV box for review with their MXQ Plus M12N model. The first part of the review will focus on specifications, accessories, and hardware design, and in the second part I’ll connect and boot the device to make a thorough review of the firmware. MXQ Plus M12N Specifications The specifications are pretty standard and comparable to the ones of yet to launch Amlogic S912 TV boxes: SoC – Amlogic S912 octa-core ARM Cortex A53 processor @ up to 2.0GHz with ARM Mali-820MP3 @ up to 750MHz System Memory – 2GB DDR3 Storage – 16GB eMMC flash and SD slot up to 32GB Video Output – HDMI 2.0a up to 4K @ 60Hz with CEC and HDR support, and AV port (composite) Audio Output – HDMI, AV (stereo audio), and optical S/PDIF Connectivity – Fast Ethernet, dual band WiFi 802.11 b/g/n/ac, […]

Multiple Videos Encoding and Decoding in Android on Firefly-RK3288 Development Board

Some applications like digital signage and video surveillance may require simultaneous video playback, and encoding to send over the network. ARM platforms may not be powerful enough to achieve those tasks with the processor only, but luckily many ARM SoCs include powerful video processing unit (VPU) capable of doing both hardware video encoding and decoding, leaving the CPU cores mostly free for other tasks. Firefly team has demoed such capabilities on their Firefly-RK3288 development board by displaying 7 videos on a single screen, including two previews from two USB cameras attached to the board, which are then encoded and decoded on the fly and displayed on the screen. The last three videos are played from 3 different files. So that means that 5 video decode and 2 video encode are running simultaneously.  The board can achieve 26 to 30fps with 720p videos, and around 13 to 15 fps with 1080p […]

How to Resolve Slow Boot Times in Ubuntu 16.04

I’ve recently upgraded my machine from Ubuntu 14.04.4 to Ubuntu 16.04.1, but while my computer used to boot in about 40 seconds, after the upgrade boot times increased considerably to 2 to 3 minutes. The first easy check was to look at dmesg:

There’s a bit 87 seconds gap between checking for the floppy, and VirtualBox drivers loading. So there’s definitely an issue here, but the log does not exactly give a clear queue. I’ve read you could use systemd-analyze to find which process(es) may be slowing down your computer at boot time:

Two processes are taking close to 8 seconds, but those 16 seconds still do not explain why it takes 2 minutes more to boot…Eventually, I realized systemd-analyze has a few more tricks up its sleeves:

The first command shows there’s no problem with the kernel itself, and something is slow in user space. The […]
