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 over. That was what happened for 4.0, after all. As …

Allwinner T2 is a Rebranded Allwinner A20 Processor Operating in Industrial Temperature Range

Allwinner-T2-SoM

Last month, Allwinner unveiled A40 and A60 industrial and military grade processors leveraging IP blocks from the old-but-popular Allwinner A20 dual core processor. This is good news for software support, as A40 and A60 should hopefully become supported in U-boot and the Linux kernel without too many efforts, as well as for companies or makers requiring wider temperature ranges in their products. However, those new processors were not pin-to-pin compatible with Allwinner A20, so a PCB redesign would be required. That’s where Allwinner T2 comes into play, as reported by Olimex, it is a rebranded Allwinner A20 dual core Cortex A7 processor with an industrial temperature range (-40 to +85 °C) that makes it suitable for automotive infotainment. I actually covered Allwinner T2 back in 2015, but at the time Allwinner did not mention anything about temperature range, and SATA support – found in A20 – was not shows in any of the documents.  The latest T2 block diagram clearly …

Linux 4.15 Release – Main Changes, Arm and MIPS Architectures

Linus Torvald has released Linux 4.15 last Sunday: After a release cycle that was unusual in so many (bad) ways, this last week was really pleasant. Quiet and small, and no last-minute panics, just small fixes for various issues. I never got a feeling that I’d need to extend things by yet another week, and 4.15 looks fine to me. Half the changes in the last week were misc driver stuff (gpu, input, networking) with the other half being a mix of networking, core kernel and arch updates (mainly x86). But all of it is tiny. So at least we had one good week. This obviously was not a pleasant release cycle, with the whole meltdown/spectre thing coming in in the middle of the cycle and not really gelling with our normal release cycle. The extra two weeks were obviously mainly due to that whole timing issue. Also, it is worth pointing out that it’s not like we’re “done” with …

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 is the “leaking_addresses” perl script, which is actually under active …

Olimex TERES-I DIY OSHW Laptop Now Up for Sale for 240 Euros

Olimex has been working on their open source hardware TERES-I DIY laptop since last year. The laptop is supposed to come in kit form, so that you can build it yourself.

Olimex Introduces 40 Euros iCE40HX8K-EVB Board with Lattice ICE40 FPGA

Last year, Olimex launched their first FPGA board with iCE40HX1K-EVB. The board is very cheap at 22 Euros, but what you can do with it is limited since it only comes with 1280 logic cells. The company has now introduced an upgraded model called iCE40HX8K-EVB with 7680 logic cells, and more I/O headers. Olimex iCE40HX8K-EVB specifications: FPGA – Lattice Semi iCE40HX8K-CT256 FPGA with 7680 logic gates, 960 Logic Array Blocks, and 128 Kbit memory System Memory – 256Kx16 SRAM (512KB SRAM) Storage – 2MB serial flash Expansion 34-pin connector to access FPGA I/Os 4x 40 pin connectors for GPIOs Debugging / Programming – 10-pin “PGM” connector Misc – 2x user buttons, reset button, 2x user LEDs, power & programming status LEDs Power Supply – 5V via power jack Dimensions – 67×65 cm The board is open source hardware with the KiCAD schematics and PCB layout, BoM, and Gerber files available on Github. Lattice IceCube2 or Project IceStorm can be used …

Olimex Launches 22 Euros ESP32-GATEWAY Board with Ethernet, WiFi and Bluetooth LE

Olimex has just launched ESP32-GATEWAY board, as cost-down version of their ESP32-EVB board, still with Ethernet, WiFi, and Bleutooth LE, but without any relays, CAN bus, nor IR control, less I/Os, and a smaller footprint. Olimex ESP32-GATEWAY specifications: Wireless Module – ESP32-WROOM32 module with 802.11 b/g/n WiFi and Bluetooth LE Wired Connectivity – 10/100M Ethernet with RJ45 jack (via LAN8710A) External Storage – micro SD slot Expansion – 20-pin GPIO connector USB – 1x micro USB port for debugging (CH340T) and power Misc – Reset and user buttons Power Supply – 5V via micro USB port Dimensions – 62 x 50 mm Another change is the lack of a LiPo charger to run the board from batteries. Just like most Olimex boards, ESP32-GATEWAY is open source hardware with KiCAD design files available on Github. The software directory is still empty, but Ethernet demo code using ESP32-IDF has been pushed for for ESP32-EVB board, and is likely to run with minor …
