H2-RK3229 is a Rockchip RK3229 TV Box with a 2.5″ SATA Drive Bay

Rockchip RK3229 is a quad core Cortex A7 for entry-level 4K TV boxes, and usually found in the cheapest TV boxes with factory price (MOQ) starting at around $18, and the bare minimum of 1GB of RAM, and 8GB of storage. Sometimes, it’s also found in higher quality models, for example Zidoo X1 II, and some models have more memory and/storage such as R-Box 4K. So I was a little surprised when I saw H2-RK3229 TV box with comes with 2GB RAM, 16GB storage, and a SATA bay for 2.5″ drives, that’s sold for around $61 shipped on Aliexpress. H2-RK3229 specifications: SoC – Rockchip RK3229 quad core ARM Cortex A7 processor @ 1.5 GHz with  ARM Mali-400MP2 System Memory – 2GB DDR3 RAM Storage – 16GB eMMC flash. 2.5″ SATA bay, micro SD slot Video & Audio Output – HDMI 2.0 up to 4K2K @ 60 fps & AV port […]

More Details about Goldmont Plus Microarchitecture (used in Gemini Lake Processors)

2017 was the year of systems based on Intel’s low power, low cost Apollo Lake processors, and provided Intel does not suddenly decide to cancel yet another product, they will be replaced by Gemini Lake processors in 2018. The former is based on Goldmont microarchitecture, while the latter relies on the updated Goldmont microarchitecture. Intel has now released a document entitled “Intel 64 and IA-32 Architectures Optimization Reference Manual” where you’ll find more gritty technical details about Goldmont Plus in chapter 16 “SOFTWARE OPTIMIZATION FOR GOLDMONT PLUS, GOLDMONT, AND SILVERMONT MICROARCHITECTURES”. The enhancements over Goldmont include: Widen previous generation Atom processor back-end pipeline to 4-wide allocation to 4-wide retire, while maintaining 3-wide fetch and decode pipeline. Enhanced branch prediction unit. Improved AES-NI instruction latency and throughput. 64KB shared second level pre-decode cache (16KB in Goldmont microarchitecture). Larger reservation station and ROB entries to support large out-of-order window. Wider integer execution […]

More Low Cost ARM Linux NAS Platforms Coming Soon: Popcorn Hour Transformer (XL), ODROID-HC2

Last summer, Hardkernel launched ODROID-HC1 Home Cloud 1 taking a single 2.5″ hard drive, and based on a modified version of their popular Exynos 5422 powered ODROID-XU4 board where they removed HDMI, and added a SATA interface (via USB 3.0), but based on the initial announcement, we also knew the Korean company was working on ODROID-HC2 supporting 3.5″ drives instead. The device is not available yet, but guys at Armbian got an early unit, so we should not be waiting too long. Hardkernel will also have some competition for their ODROID-HC1 NAS, as Cloud Media (and Pine64?) are working on Rockchip RK3328 based Popcorn Hour Transformer & Transformer XL with support for 2.5″ and 3.5″ drives respectively. Hardkernel ODROID-HC2 ODROID-HC2 preliminary specifications: SoC – Samsung Exynos 5422 octa-core processor with 4x ARM Cortex-A15 @ 2.0 GHz, 4x ARM Cortex-A7 @ 1.4GHz, and Mali-T628 MP6 GPU supporting OpenGL ES 3.0 / […]

Linux 4.14 Release – Main Changes, ARM & MIPS Architecture

Linus Torvalds has announced the release of Linux 4.14: No surprises this week, although it is probably worth pointing out how the 0day robot has been getting even better (it was very useful before, but Fengguang has been working on making it even better, and reporting the problems it has found). Sure, some of the new reports turned out to be just 0day doing things that just don’t work (ie KASAN with old gcc versions, but also doing things like loading old ISA drivers in situations that just don’t make sense – remember when you couldn’t even ask if the hardware existed or not, and just had to know), but even then it’s been all good. The appended shortlog is obviously only for the (small) haul since rc8, and it really is tiny. Not very many commits, and they are small. The biggest thing that stands out in the diffstat […]

Olimex Introduces Universal Systems-on-Module with 204-pin SO-DIMM Edge Connector

Olimex has designed several system-on-modules (SoM) over the years for on various processors such as Rockchip RK3188, TI AM3352, or Allwinner A20, and each time they focus on exposing as many pins as possible from the SoC. That’s nice for some application, but it also means SoM with different processor are not compatible, and you can’t simply design a single baseboard for all those SoMs. Olimex then realized many customers wanted an upgrade path for the SoM without having to redesigned the baseboard, and most were using the same common interfaces, so a family of compatible SoMs was needed. While there are already many system-on-module standards available, the company decided to roll their own SoM form factor based on the 204-pin SO-DIMM edge connector. The first SoM based on the standard will be A20-SOM204 powered by the popular Allwinner A20 processor. All SoM following this standard will expose the following […]

Upgrading Sonoff Stock Firmware to Sonoff-Tasmota – USB to Serial, and OTA Update Methods

This post was initially supposed to be part 2 of Sonoff B1 light bulb review, where I would have explained how easy it was to use OTA mechanism to update to Sonoff-Tasmota open source firmware, and shortly show about its features and capabilities. However, it took me over 10 hours to make that work, mostly due to misunderstand in the documentation, and time spent to configure routers. I also failed the first time with Sonoff B1, so I used the serial console method, and instead managed to use SonOTA method with Sonoff POW switching from stock firmware to Sonoff-Tasmota without having to solder or tear down anything. Updating software with a USB to Serial Board Using a USB to serial board is the most common method to switch from stock firmware to open source firmware such as ESPurna or Sonoff-Tasmota in Sonoff devices or other ESP8266 based devices. It’s quite […]
