Meet NXP i.MX8 Processor Families: i.MX 8 for High performance, i.MX 8M for Audio/Video & i.MX 8X for Low Power

Freescale and then NXP have been talking about i.MX8 processors for several years, and this spring unveiled i.MX 8 Multisensory Enablement Kit without giving much details about the processor except it would include both Cortex A72 & A53 cores. But NXP put out a press release yesterday about “Multisensory Automotive eCockpit Platform to Advance Multimedia Experiences in Future Cars” which appears to be the same news but with different words, except the content of the PR has more interesting bits such as: The new family, which is based on up to six 64-bit ARMv8-A technology processor cores and includes a HiFi 4 DSP, LPDDR4 and DDR4 memory support as well as dual Gigabit Ethernet with audio video bridging (AVB) capability, is designed to advance automotive dashboard graphics such as instrument clusters, infotainment visuals, heads-up displays, rear-seat screens and more. Capable of driving four HD screens with independent content or a […]

VoCore2 WiFi IoT Board Launched with Audio, PoE & “Ultimate” Docks (Crowdfunding)

Vocore WiFi IoT board was popular at its launch in 2014 because affordable WiFi boards with I/Os were not common at the time, and it came with an Ethernet dock making it a complete router within a tiny and cute cube. The developers have been working on VoCore2 (aka Vocore V2) with a faster processor, more memory, a lower power consumption, a better WiFi signal, and more I/Os for several months, and have now launched the board on Indiegogo aiming to raise at least $6,000 for mass production. Vocore2 board specifications: SoC – Mediatek MT7628AN MIPS processor @ 580 MHz System Memory – 128 MB DDR2 Storage – 16MB NOR FLASH, 1x SDXC via I/O pins Connectivity WiFi 802.11n 2T2R up to 300 Mbps with either 2 u.FL connector or 1 u.FL connector + on-board chip antenna (Max signal output >19.5dbm peak) 2x 10/100M Ethernet interfaces via I/O pins I/Os […]

V-Bridge Muses Digital TV Modulator Boards Let You Broadcast Your Own TV Channel for $199 and Up (Crowdfunding)

I wrote about VATek VMB8202D Enmoder SoC handling both DVB, ATSC, DTMB and ISDB modulation and H.264 hardware encoding earlier this summer, and at the time, the company also planned to launch a crowdfunding campaign for two open source hardware DTV modulation boards in a couple of weeks. Weeks turned into months, but finally V-Bridge Muses boards and video input & RF daughterboards have now launched on Kickstarter where you can get your own live video broadcasting board for $199 and up. MUSES-α board MUSES-α board is the cheapest of the two boards, and features a header for the RF daughter board, and a USB port to connect to a computer. MUSES-α board specifications: SoC – VATek A1 32-bit RISC modulator chip Storage – SPI flash (unclear whether it can be accessed/modified by user) Modulation – DVB-T/C, ATSC/QAM, DTMB; RF header Video Encoding – N/A (handled by PC via USB […]

Xtream Codes IPTV Panel Review – Part 2: Movie Data Editing, Security, Resellers, Users and Pricing Management

Dear readers, after part 1 of Xtream Codes Panel v.2.2.0 EVO review, here is part 2. I tried hard to get all in two parts, but “to be exhaustive” there will also have to be a part 3… Movie Editing Section As we can see, it’s only possible to assign a movie into a single category, a SELECT BOUQUET Option under the Category would be more then useful. So while Movie Editor Section is useful right now, it still needs improvement. Also taking each movie by hand for editing, after, for example, a Main server crash or changing the Main, is really something, a waste of time. Some of the issues / possible improvements include: No mass edit of movies to bouquets If changing the category of a movie, I found no working method to change in a bulk.. Even if I tried to delete the “content” of a bouquet, […]

Linux 4.8 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has officially released Linux 4.8 last Sunday: So the last week was really quiet, which maybe means that I could probably just have skipped rc8 after all. Oh well, no real harm done. This obviously means that the merge window for 4.9 is open, and I appreciate the people who already sent in some pull requests early due to upcoming travel or other reasons. I’ll start pulling things tomorrow, and have even the most eager developers and testers hopefully test the final 4.8 release before the next development kernels start coming 😉 Anyway, there’s a few stragging fixes since rc8 listed below: it’s a mixture of arch fixes (arm, mips, sparc, x86), drivers (networking, nvdimm, gpu) and generic code (some core networking, with a few filesystem, cgroup and and vm things). All of it pretty small, and there really aren’t that many of them. Go forth and test, […]

How to check HTTP Header and Connection Stats from the Command Line

A few days ago, I discussed with somebody whether a file was cached by Cloudflare or not, and this involved getting the HTTP header, and checking for CF-RAY field to see if data is going through one of Cloudflare data centers. This can be done with curl:

curl -svo /dev/null http://www.cnx-software.com
* Rebuilt URL to: http://www.cnx-software.com/
*   Trying 104.28.19.95...
* Connected to www.cnx-software.com (104.28.19.95) port 80 (#0)

In the command above, -s stands for silent so that curl does not show the progress meter, -v stands for verbose to show the header, and -o /dev/null is used to discard the packet load. You can also use -I option (fetch the HTTP-header only) with curl, which – if all you need is the HTTP header – provides a cleaner output:

curl -I http://www.cnx-software.com

I also came across httpstat Python script recently via n0where, doing much of the same thing, except it also adds transfer statistics. It can be installed by downloading httpstat.py, or better using pip:

sudo pip install httpstat

Gumstix Nodana 96BCE 96Boards Compatible Baseboard Takes Intel Joule Module

96Boards is an initiative from Linaro, an engineering organization focusing on ARM development, to define some hardware and software specifications for development boards. But since 96Boards specifications are open, Gumstix decided to create the first x86 board compliant with 96Boards CE hardware specifications with Nodana 96BCE baseboard powered by Intel Joule Module. For obvious reasons, this will never be an officially supported 96Boards.org platform. Nodana 96BCE board specifications: SoM – Intel Joule Module based on Intel Atom T5700 or T5500 processor with up to 16GB storage, 4GB RAM. External Storage – 1x micro SD card Video Output – 1x HDMI port USB – 2x USB 3.0 ports, 1x USB 3.0 type C port Expansion Headers 96Boards Low Speed connector with I2C, SPI and UART 96Board High Speed connector with MIPI DSI and USB 2.0 Power Supply – 8 to 18 V (if it follows 96Boards CE specs) Dimensions – 85 […]

Review of Allo Vana Player Linux HiFi Audio System with Max2Play, SqueezeBox and Kodi

Last month I showcased what I called “Allo Sparky Audio Kit” with a DAC board (Piano), an amplifier board (Volt), and usually hard to find reclocker and capacitance multiplier boards (Kali & CM), all connected to Allo Sparky ARM Linux development board powered by Actions Semi S500 quad core Cortex A9 processor, and running Ubuntu 12.04. In the first post, I just described the boards, and showed how to assemble the kit, but now that I have received the user’s manual, it turns out the kit is actually called “Vana Player” and the provided Ubuntu firmware image runs Max2Play Browser based system that’s also available for Raspberry Pi and ODROID boards. Before starting the kit, you’ll need to connect speakers to Piano DAC board and/or Kali board, as well as a 19.5V power source such as a laptop power supply to connect to the CM board. I connected some USB […]
