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 […]

Factory Prices of Some TV Boxes and Accessories

Some companies that contact me have not read the about section of the blog, and either tell me they can give me a good price for TV boxes, and some even send me their price list. And this morning, I’ve received a EXW (Ex Works) price list this of Amlogic S912/S905X/S905W and Rockchip based TV boxes, as well as some air mice, and Android projectors. The cheapest models are based on S905W and RK3229, with MXQ Pro 1GB/8GB going for $17.5 per unit for 200 pieces orders. For reference that models goes for around $26 shipped online before any discount coupon you may find. At the other end of the scale, you have TX2 model with 3GB RAM, 64GB flash going for $77.5 EXW for 200-unit orders, and sold online for $86 including shipping, again before coupon. Margin must be really low, or the prices above are not that competitive, […]

Linux 4.13 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has just announced the release of Linux 4.13 and a kidney stone…: So last week was actually somewhat eventful, but not enough to push me to delay 4.13. Most of the changes since rc7 are actually networking fixes, the bulk of them to various drivers. With apologies to the authors of said patches, they don’t look all that interesting (which is definitely exactly what you want just before a release). Details in the appended shortlog. Note that the shortlog below is obviously only since rc7 – the _full_4.13 log is much too big to post and nobody sane would read it. So if you’re interested in all the rest of it, get the git tree and limit the logs to the files you are interested in if you crave details. No, the excitement was largely in the mmu notification layer, where we had a fairly last-minute regression and […]

Rockchip Has Setup an Official Open Source Website with Software & Hardware Documentation, Source Code

As a young engineer, I first understood the importance of good documentation thanks to an incomplete Holtek MCU datasheet that made us waste weeks of development, and the value open source software thanks to Sigma Designs’ SDK that was full of binary blobs with our applications often crashing inside those, leading to software development delays, especially since we had access to limited support. More recently, if you ever worked with the most popular Chinese processors found in ARM Linux development board, usually made by Allwinner, Amlogic, or Rockchip, you must have gone through roadblocks due to a lack of documentation and software support. So far, Allwinner is purely relying on linux-sunxi community and “leaks” of their documentation and SDKs, while Amlogic has had their “open linux” microsite for several years, but you won’t find complete documentation like technical reference manual, schematics, and part of the source code requires you to […]
