Beelink GT1 TV Box Review – Part 2: Android Marshmallow Firmware

I’ve previously reviewed other Amlogic S912 TV boxes such as M12N MXQ Plus or Qintaix Q912, but Beelink GT1 has the advantage of being quite cheaper at $56 and up, but still come with many of the same features as more expensive devices. I’ve already posted pictures, and checked out the hardware design in the first part of Beelink GT1 review, so in the second part I’ll report my experience with Android, including video and audio capabilities, hardware features testing, and some benchmarks. First Boot, OTA Firmware Update, Settings, and First Impressions The device comes with two USB ports only, so I connected a USB hard drive to one of the port, and a USB hub to the other with the RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, as well as a USB keyboard to take screenshots. I completed the setup by adding […]

Test Widevine & PlayReady DRM, HDCP 1.x/2.x, 4K VP9 and H.265 in Android with Exoplayer App

I first heard about ExoPlayer in an Android TV Overview presentation at Linaro Connect 2014, but I never really looked into it. The source code is available on Github, and I’ve been given ExoPlayer.apk [Update April 2020: Exoplayer binary is now available on Apkpure] as it can be used to test UHD H265 support, HDCP 1.x, HDCP 2.x compatibility, PlayReady & Widevine DRM using different format and so on. So I installed it on Beelink GT1 Android TV box which I’m currently reviewing, and only include basic Widewine Level 3 DRM, and certainly does not support HDCP features. There are 9 sections in the app to test various videos and DRM schemes: YouTube Dash Widevine Dash Policy Tests (GTS) – Widewine with or without HDCP, with or without secure video path Widevine HDCP Capabilities Tests – NoHDCP, HDCP 1.0, HDCP 1.1, HDCP 2.0, HDCP 2.1, HDCP 2.2, and HDCP no […]

Zidoo X9S Android Media Center Review – Part 2: Android Firmware & OpenWrt (NAS Functions)

Zidoo X9S is more than a simple Android TV box, as it supports NAS function via OpenWrt running simultaneously with Android 6.0 and its USB 3.0 and SATA ports, as well as HDMI input function capable of recording and broadcasting videos, and supporting Picture-in-picture, so I find “Android Media Center” better fit the description for this device. I’ve already taken pictures of the Zidoo X9S and its board in the first part of the review, so I’ll test both Android 6.0 & OpenWrt firmware, and the most of the features in the second part of the review. Initial Setup and First Boot I connected the usual accessories and cables to the box including a USB 3.0 hard drive, HDMI and Ethernet cables, USB RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, and a USB keyboard to take screenshots. I also added a 1TB SATA […]

Zidoo X9S Android TV Box HDMI Input Testing – Video Recording, PiP, and UDP Broadcasting

One of Zidoo X9S media center‘s key features is its HDMI Input port with support for PVR, picture-in-picture, and video broadcasting over UDP. The company has come a long way since the implementation of HDMI input on Zidoo X9 TV box, which would only support PVR function, and exclusively work in the foreground. For this review, I connected K1 Plus T2 S2 Android TV box to the HDMI input of Zidoo X9S, and started HDMI In app.The first good news is that HDMI input does work, as we can see K1 Plus user interface preview inside Zidoo X9S’ HDMI IN app. Before testing all features, let’s go through the options for Video, Audio, and Output. You can select various video resolution up to 1080p, but I left it to Auto, which for this test meant 1080p. Framerate cannot be changed and is set to Auto, while bitrate ranges from 1M […]

How to Write ESP8266 Firmware from Scratch (using ESP Bare Metal SDK and C Language)

CNXSoft: This is a guest post by Alexander Alashkin, software engineer in Cesanta, working on Mongoose Embedded Web Server. Espressif’s ESP8266 had quite an evolution. Some may even call it controversial. It all started with ESP8266 being a WiFi module with a basic UART interface. But later it became clear that it’s powerful enough for embedded system. It’s essentially a module that can be used for running full-fledged applications. Espressif realized this as well and released an SDK. As first versions go, it was full of bugs but since has become significantly better. Another SDK was released which offered FreeRTOS ported to ESP. Here, I want to talk about the non-OS version. Of course, there are third-party firmwares which offer support for script language to simplify development (just Google for these), but ESP8266 is still a microchip (emphasis on MICRO) and using script language might be overkill. So what we […]

Hacking ARM TrustZone / Secure Boot on Amlogic S905 SoC

Amlogic S905 processor used in many Android TV boxes and ODROID-C2 development board implements ARM TrustZone security extensions to run a Trusted Execution Environment (TEE) used for DRM & other security features. However, Frédéric Basse, a security engineer, worked with others and managed to bypass secure boot in one Amlogic S905 powered Android TV box, namely Inphic i7, but any other device based on the processor would have made the same thing possible. He explains the steps they went through and how they managed to exploit vulnerability to bypass secure boot in a detailed technical blog post. They first started by looking for info in Amlogic S905 datasheet, but most info about TrustZone had been removed from the public version. So not that much help here except a potential address for BOM Root (ROMBOOT_START 0xD9040000). The next step was to connect the UART pins in order to access the […]

Routers, IP Cameras/Phones & IoT Devices can be Security Risks even with the Latest Firmware, and a Strong Admin Password

I’ve just read an interesting article entitled “who makes the IoT things under attack“, explaining that devices connected to the Internet such as router, IP cameras, IP Phones, etc.. may be used by Botnet to launch DDoS attacks, and they do so using the default username and password. So you may think once you’ve updated the firmware when available, and changes the default admin/admin in the user interface, you’d be relatively safe. You’d be wrong, because the malware mentioned in the article, Mirai, uses Telnet or SSH trying a bunch of default username and password. That made me curious, so I scanned the ports on my TP-Link wireless router and ZTE ZXHN F600W fiber-to-the-home GPON modem pictured below, and installed by my Internet provider, the biggest in the country I live, so there may be hundred of thousands or millions of such modems in the country with the same default […]
