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 […]

Rikomagic MK22 Octa-core Android TV Box Review – Part 1: Unboxing and Teardown

Rikomagic became a much better known company when they launched MK802 TV stick in 2012, and over the years they’ve kept introducing new products, and I’ve just received a review sample of their latest Rikomagic MK22 octa-core Android TV box powered by Amlogic S912 processor. I’ve posted photos of the device and its accessories, and check out the hardware design in the first part of the review, before testing Android 6.0 firmware in the second part in a few weeks. Rikomagic MK22 Unboxing I received MK22 in its black and white retail package. The back of the package details the main features, and the hardware specifications. Instead of printing a user’s manual that anybody will hardly read, the company instead printed a QR Core to MK22 user’s manual download link. The TV box ships with a 5V/2.5A power supply, an HDMI cable, and an IR remote control that looks the […]

R-Box Pro is just another Amlogic S912 TV box, except it comes with up to 3GB RAM, against 2GB for most other models on the market. Kingnovel sent me a sample with 3GB RAM to check it out, and today I’ll start by taking photos of the devices, and perform a teardown mostly to find out how the 3GB memory design is implemented. R-Box Pro Unboxing The retail package is minimal black box with “OTT TV Box Amlogic S912” and “R-Box Pro” markings and Kodi logo.

The day I received the sample the top cover looked to have many scratches, but after removing the plastic film on the […]

Rockchip RK3399 Benchmarks Appear on GeekBench

Rockchip RK3399 hexa-core processor with ARM Cortex A72 and A53 cores and a Mali-T860MP GPU will soon be found in TV boxes, development boards, tablets, Chromebooks, virtual reality headset and more, and is widely expected to offer a significant performance boost against previous Rockchip processors, including RK3288, and outperform SoCs from competitors like Amlogic and Allwinner. We can have a first clue about the performance as Rockchip RK3399 boxes and one tablet are now showing up on GeekBench. The box is clocked at 1512 MHz, while the tablet is limited to 1416 MHz, but overall single-core score is about 1350 points, while multi-core score hovers around 2,550 points. I’m not that familiar with GeekBench so number don’t tell me anything. Let’s compare it against RK3288 which CPU-wise is the fastest processor I known of from Chinese silicon vendors targeting TV boxes. There’s a significant single-core performance boost (+73%), and lower […]

TV Box Market Data (for China): Weekly Sales, Average Prices, Most Popular Devices & Streaming Services

I’ve recently seen a tweet from IloveRockchip twitter account about the weekly sales data, and market share of octa-core, quad-core, and other OTT TV boxes. The chart below shows 108,000 Android TV boxes were sold on the 37th week of 2016 (September 12 – 18), and that while quad core TV boxes still held 77% market share that week, octa-core sales grew by 108%. The downside is that the data is only for the Chinese market. But I still found interesting to investigate whether I could get more information. The research company, All View Cloud, will release weekly data to their paid customers, but a free sample report for Week 21 (16-22 May) can be downloaded from their website (N.B.: The link does not work in Firefox for me, but it does in Chrome). “SALES” must be the quantity, roughly between 100,000 and 150,000 units sold per week, and if […]
