Many Linux command line tools, such as ls or du, have a “human” option to make it more readable by… humans. When you want to get the kernel log, to find otu potential problems, you’d usually run dmesg, which dump the complete log in one go and looks like: [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Initializing cgroup subsys cpuacct [ 0.000000] Linux version 3.11.0-15-generic (buildd@roseapple) (gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu8) ) #25-Ubuntu SMP Thu Jan 30 17:22:01 UTC 2014 (Ubuntu 3.11.0-15.25-generic 3.11.10) [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-3.11.0-15-generic root=UUID=9c042788-fa75-4fc4-9b12-598c809410e8 ro quiet splash [ 0.000000] KERNEL supported cpus: [ 0.000000] Intel GenuineIntel [ 0.000000] AMD AuthenticAMD [ 0.000000] Centaur CentaurHauls [ 0.000000] e820: BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009f7ff] usable [ 0.000000] BIOS-e820: [mem 0x000000000009f800-0x000000000009ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000000f0000-0x00000000000fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x00000000bfd9ffff] usable [ 0.000000] BIOS-e820: […]
AllWinner Linux-sunxi Community Presentation and Status Report – FOSDEM 2014
Oliver Schinagl, a member of linux-sunxi community working on open source kernel and bootloader for AllWinner SoCs, has given a presentation of the community at FOSDEM 2014 to give an overview, and show what progress has been made to date. I’ll write a summary in this post, but if you want to watch the video and/or access the slides scroll down at the bottom of the post. After explaining what sunxi is, and introducing himself, he gave some information about AllWinner and their SoCs: Founded in 2007 in Zhuhai, Chiang now with 550 employees including 450+ engineers 15% market share in 2013 for tablet SoCs, only behind Apple. Products: F-series SoC (2010), A10 (2011), A13, A10s (2012), and A20 (2013). (cnsoft He skipped A31(s) and A80 here as they are not really supported by the community). They list “Open Source Source” and “GPLv3” in their marketing materials although they clearly […]
Applied Micro X-Gene X-C1 ARMv8 Server Development Board is Now Available for Pre-order
Applied Micro X-Gene is the very first processor to use ARM 64-bit architecture (ARMv8), not Cortex A53 or Cortex A57, but a custom implementation, and last year we’ve seen the company’s ARMv8 development board running 4 Linux virtual machines via KVM. The platform, called X-Gene X-C1, can now be pre-ordered to develop private cloud, public cloud, and enterprise applications. There’s limited public information for now, but I could derive specifications from a few places on the web and available pictures: SoC – Applied Micro X-Gene eight core ARMv8 processor @ 2+GHz System Memory – 2x DDR3 memory slots Storage – 4x SATA 2/3 ports + SD card slot Connectivity – 3x 10 Gb Ethernet ports USB – 2x SuperSpeed USB 3.0 ports, 1x mini USB port Expansion – PCIe Gen 3 Monitoring DB9 Serial port Power – ATX I don’t know what’s the metallic connector with holes between the two […]
IGEPv5 OMAP5432 Development Board is Now Available for 149 Euros
ISEE IGEPv5 development board announced in October 2013, and powered by Texas Instrument OMAP5432 dual core Cortex A15 + dual core Cortex M4 SoC, POWERVR SGX544MP2 and Vivante GC320 GPUs is now available for as low as 149 Euros. There are two versions: “IGEPv5 OMAP5432 Communication Edition” for hobbyists with limited support, and “IGEPv5 OMAP5432” directly supported by ISEE. There’s also “IGEPv5 Custom Design” if you have specific requirements for your product. Hardware specifications are shared by both versions but with significant differences (CE = IGEPv5 OMAP5432 Community Edition, ISEE = IGEPv5 OMAP5432): SoC – Texas Instruments OMAP5432 dual core Cortex A15 up to 1.5 GHz (CE) or 2 GHz (ISEE), dual core Cortex M4, with POWERVR SGX544 dual-core GPU, Vivante GC320 GPU, and TMS320DMC64x DSP System Memory CE – 1GB DDR3 @ 1066 MHz ISEE – Up to 4 GB DDR3 RAM expandable to 4GB Storage CE – No eMMC, […]
Intel Bay Trail Z3700 Series Overview, Benchmarks, Hardware, Documentation and Linux Support
After seeing the discussion about ARM vs x86 (Bay trail) for the future Dragon Pyra open source game console, I’ve realized many people, including myself, do not know about the different resources available to develop hardware and software for Intel Bay Trail SoCs for tablets such as Atom Z3740 and Z3770, so I decided to have a look. Intel Atom Bay Trail Z3700 Series Overview Intel Z3600 series and Z3700 series are respectively dual core and quad core Bay Trail-T SoCs for Android and Windows 8 tablets. There are 4 quad core models: Z3740, Z3740D, Z3770, and Z3770D, and 2 dual core processors: Z3680 and Z3680D. The dual core versions are reserved for Android only, and there’s no product page on Intel for now, so I’ll focus this post on Z3700 series only. I have no idea what the “D” in Z3740D is for, except it;’s not related to Desktop, […]
How to Convert Your HDTV into a Massive Touchscreen Enabled Android Tablet
Thanks to Android mini PCs, it’s now very easy and cheap to run Android on your HDTV, but most of the time touchscreen functionality is missing. There are already full products such as AIO Android PCs, and Smart Displays that brings Android to large display with touchscreen, and PQ Labs iStick A200 HDMI TV stick supports directly their overlay touch frames so you can “touchscreenize” your TV with their mini-PC and correct frame connected via USB. If you’d rather use another model of infrared touch frame for your TV and own Android device, Hardkernel has just explained how to do in the February edition of ODROID magazine using their ODROID-XU development board. In the magazine, they explain some details about the difference between capacitive and infrared touchscreens, and provide instructions to choose the right IR touch frame, how-to modify the software if necessary, and how to connect the touch frame to […]
Keepod Unite Aims to Bring Computer Access to Africa with $7 USB Sticks and Refurbished Laptops (Crowdfunding)
The Raspberry Pi foundation has done a great job to bring to market $25 and $35 computers for kids to learn programming, but they have many other uses including hardware “hacking” and bringing low cost computers to developing countries. Keepod and NGO LiveInSlums have thought of an apparently more cost effective way to bring computing access to people living in slums in Nairobi, Kenya, by providing USB sticks (about $7) to boot refurbished laptops. This is absolutely NOT a $7 PC as a few other websites have mentioned. The goal is to facilitate NGO communication, the spread of knowledge and economic development in a way that’s personal and secure. The USB flash drives will belong to one person, and contains a Linux based operating systems with all files saved in the stick, and no modifications on the host computer which does not even need an hard drive to work, and […]
DragonBox Pyra Open Source Handheld Game Console To Feature TI OMAP5432 SoC.. or AllWinner A80, or Intel Bay Trail, or Qualcomm Snapdragon…
Pandora is an open source handheld console which development started as far back as 2007. The project has had ups and downs, and some people have yet to receive the device they pre-ordered. As many components are now more difficult to source, Pandora has reach end-of-life, as Pandora 2 is now being developed with a subset of the original team, but has been renamed to DragonBox Pyra to start afresh. The new version aims to take to the good aspects of the original Pandora, and improve on the bad ones, so that DragonBox will have a faster hardware with a better looking case and better control. Here are the specifications listed on the project website: SoC – Texas Instruments OMAP 5432 SoC with 2x ARM Cortex-A15 @ 1.7Ghz with NEON SIMD, 2x ARM Cortex-M4, Imagination Technologies PowerVR SGX544-MP2 GPU for 3D graphic, and Vivante GC320 GPU for 2D graphics System […]
