Linux 5.2 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linux 5.2 Changelog

Linus Torvalds announced the release of Linux 5.2 last Sunday: So I was somewhat pre-disposed towards making an rc8, simply because of my travels and being entirely off the internet for a few days last week, and with spotty internet for a few days before that [*]. But there really doesn’t seem to be any reason for another rc, since it’s been very quiet. Yes, I had a few pull requests since rc7, but they were all small, and I had many more that are for the upcoming merge window. Part of it may be due to the July 4th week, of course, but whatever – I’ll take the quiet week as a good sign. So despite a fairly late core revert, I don’t see any real reason for another week of rc, and so we have a v5.2 with the normal release timing. There’s no particular area that stands […]

Top 5 Raspberry Pi Alternatives in 2019

Raspberry Pi Alternatives 2019

The Raspberry Pi boards are great little Arm Linux SBC’s with a low price and great community support. But the Broadcom processors used in the boards are also fairly old so they may not be suitable for some projects. If your application needs or would benefit from modern features such as memory over 1GB RAM, an actual Gigabit Ethernet port, USB 3.0 port(s), 4K video output, or H.265 hardware video decoding you’ll have to find Raspberry Pi alternatives. I’ll point out 5 alternative single board computers in this post from the point of view of existing Raspberry Pi users, who will want good software support and a board with the same or similar form factor as Raspberry Pi 3 Model B/B+ in order to reuse their add-on boards and/or enclosures. Price has to be competitive as well, so nothing above $80 will be mentioned. The boards are not listed in […]

Geniatech ATV1660K TV Box Supports Dual HDMI Output, HDMI Input

Android TV Box Dual HDMI Output

There are many applications that may benefit from dual display support from digital signage to healthcare to retail or entertainment either to provide access to two different output for the service provider and customer or simply to mirror content.  Most Android TV boxes only come with one display output however, so in most cases, you’d have to switch to an Intel mini PC or add a USB-C display adapter if supported by the hardware. Geniatech ATV1660K TV box supports dual HDMI output out of the box, as well as HDMI input. The Android 5.1 TV box is powered by the time-tested Rockchip RK3288 processor and comes with 2GB RAM and 16GB storage by default. Geniatech ATV1660K specifications: SoC – Rockchip RK3288 quad-core Arm Cortex-A17 processor at up to 1.8GHz, with Mali-T764 GPU System Memory – 2GB DDR3 (1GB optional) Storage – 16GB eMMC flash (4GB-32GB optional), full-size SD card slot […]

Linux 5.0 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linux 5.0 Changelog

Linus Torvalds has just released Linux 5.0: Ok, so the last week of the 5.0 release wasn’t entirely quiet, but it’s a lot smaller than rc8 was, and on the whole I’m happy that I delayed a week and did an rc8. It turns out that the actual patch that I talked about in the rc8 release wasn’t the worrisome bug I had thought: yes, we had an uninitialized variable, but the reason we hadn’t immediately noticed it due to a warning was that the way gcc works, the compiler had basically initialized it for us to the right value. So the same thing that caused not the lack of warning, also effectively meant that the fix was a no-op in practice. But hey, we had other bug fixes come in that actually did matter, and the uninitialized variable _could_ have been a problem with another compiler. Regardless – all […]

Spare TV Box Board Sold for MXQ-4Q / MXQPro DIY Repairs

Spare TV Box board

Once somebody asked me if spare TV box boards were available for purchase since his TV box died after a few months, and he wanted to repair it himself without having to purchase another complete TV box. Usually, such boards are not sold, except maybe on Alibaba, where you may or may not have to purchase in quantities. So I basically told him it would be hard to find, and buying a new or second hand TV box would be a better option. But I was recently made aware that at least one seller was offering spare TV box boards for MXQ-4Q and MXQPro on Aliexpress for $20.61 shipped in order to let people repair their boxes themselves. If your goal is to repair a TV box, I can only think of two reasons for buying a spare TV box board: saving money and/or reducing electronics waste. MXQ-4Q and MXQPro […]

Flashing Firmware to Rockchip Devices in Linux with rkdeveloptool Open Source Utility

Rockchip rockusb mode

It’s been possible to flash firmware to Rockchip devices in Linux with upgrade_tool command line tool for many years, but the utility is closed-source and only supports “RK Firmware” files that are also used for OTA firmware updates, but not “raw firmware” that you’d flash directly to micro SD cards for example. This week-end as I played with ROC-RK3328-CC board, I encountered some instability issues with micro SD cards, so I instead relied on an eMMC flash module. The only problem was that Firefly Team only releases “raw firmware” files, so I was unable to use upgrade_tool, and instead found out rkdeveloptool  open source utility was used to flash raw firmware images in Firefly’s Wiki. The first step is to connect a male to male USB  Type A cable (like that one on eBay)  between the board and the host computer, and connect a USB power adapter to the board. […]

Linux 4.17 Release – Main Changes, Arm & MIPS Architectures

Linus Torvalds released Linux 4.17 last Sunday: So this last week was pretty calm, even if the pattern of most of the stuff coming in on a Friday made it feel less so as the weekend approached. And while I would have liked even less changes, I really didn’t get the feeling that another week would help the release in any way, so here we are, with 4.17 released. No, I didn’t call it 5.0, even though all the git object count numerology was in place for that. It will happen in the not _too_distant future, and I’m told all the release scripts on kernel.org are ready for it, but I didn’t feel there was any real reason for it. I suspect that around 4.20 – which is I run out of fingers and toes to keep track of minor releases, and thus start getting mightily confused – I’ll switch […]
