Emcraft Releases Linux BSP for NXP i.MX RT1050 Cortex M7 Evaluation Board

NXP iMX RT series is a family of ARM Cortex M7 processors clocked at 600 MHz, making the solution a “crossover embedded processor” bridging the gap between real-time capabilities of micro-controllers and the performance of application processors. This week, NXP provided some benchmark numbers for i.MX RT1050 processor, which delivers a CoreMark score of 3020, DMIPS of 1284, and 20ns interrupt latency at 600 MHz, which means it could be a good candidate for embedded Linux, and Emcraft Systems has just released a uCLinux BSP for the NXP i.MX RT1050 EVK board. The BSP features U-Boot v2017.09-rc1, Linux Kernel 4.5 with relevant device drivers such as key I/O interfaces, Wi-Fi, SD card, LCD, etc…, and GNU development tools such as a GCC 4.7 toolchain, GDB, and so on. The company has made a demo with a GUI application designed with Crank Software’s Storyboard Suite, and running in Linux on the […]

Use your Smartphone as an IR Remote Control with ROCK USB Type C IR Remote Control Transmitter

A few years ago, I wrote about ZazaRemote transforming your smartphone into a universal IR remote control. ZazaRemote is a hardware and software solution that combines infrared dongles micro USB port or 3.5mm audio plug, and a mobile app that allows you to control all sort of devices (TV, aircon, etc…) from your smartphone. Over three years later, more and more phones are now deprived from the audio jack, and micro USB ports have given way to USB type C ports, so that solution does not work anymore on newer phones. Some of the recent phones like Xiaomi Mi A1 integrate an IR transmitter, but for others, Zazaremote’s developer (Tiqiaa) has apparently not come up with a USB type C version, but just sells micro USB to USB type C adapters, not the most convenient. Upon further research, I eventually found a USB type C IR transmitter for smartphone sold […]

Sonoff Wireless Switch Family Gets a $3 IP66 Waterproof Enclosure

ESP8266 powered ITEAD Studio Sonoff wireless switches have been popular because they are inexpensive, highly customizable thanks to work from the community leading to open source projects such as ESPurna and Sonoff-Tasmota, and come fully packaged so you don’t need to make your own case for it. That works well for indoor projects, but if you needed to control outdoors lights, gate, water pump, etc… you had to protect the device from humidity/rain. That may not be necessary anymore as the company is now selling Sonoff Basic with an IP66 waterproof enclosure for $7.75, or the case only for $2.90.Sonoff waterproof case: Ingress Protection Rating – IP66 Material – PC V0 Dimensions – 132.2 x 68.7 x 50.1mm (See details) Weight – 145.0g IP66 rating is not suitable for prolonged immersion, but it should be good to protect against rain or high humidity. The box ships with two standardized PG7 […]

iMX7-96 “Meerkat” ARM Cortex A7/M4 Development Board Launched for $109

If you have really good memory, you may remember that Freescale was working on a 96Boards compliant i.MX 7 development board in 2015 that was supposed to be released in Q4 of that year. Yesterday the board was finally launched and demonstrated on 96Boards OpenHours. i.MX7-96 board (aka Meerkat) is powered by an NXP i.MX 7 dual core ARM Cortex-A7 + 1x Cortex M4 processor, coupled with 512MB RAM, and complies with the Consumer Edition (CE) of 96Boards specifications. iMX7 96 board specifications: SoC – NXP i.MX 7Dual dual ARM Cortex-A7 processor at 1.2 GHz, with Cortex-M4 @ 200 MHz and 2D accelerator System Memory – 512 MB DRAM Storage – micro SD slot Video Output – HDMI Connectivity  – 802.11 b/g/n WiFi + Bluetooth 4.1 LE (LSR Sterling-LWB module) USB – 2x USB 2.0 hosts,  1x micro USB 2.0 OTG Camera – 1x  MIPI-CSI Expansion Interfaces 40-pin low speed […]

Linux Benchmarks – Intel J3455 Apollo Lake vs Z3735F Bay Trail vs RK3399 and Other ARM Platforms

Since I’ve just installed Ubuntu 17.10 on MeLE PCG35 Apo, I decided I should also run some benchmarks comparing with other ARM and x86 Linux platforms I’ve tested in the past.I was particularly interested to compare the performance of Intel Apollo Lake processors (Celeron J3455 in this case) against higher end ARM processors like Rockchip RK3399 (2x A72, 4x A53) since systems have a similar price (~$150+), as well as against the older Bay Trail processor to see the progress achieved over the last 2 to 3 years. To do so, I used Phoronix Benchmark Suite against Videostrong VS-RK3399 results (RK3399 development board):

The benchmark first issued a warning about “powersave” governor, but I still went ahead, and once completed I change it to “performance” governor:

…and ran the tests again. All results are available on OpenBenchmarking. Let’s address the governor results first. cpufreq-info reports that powersave governor […]

MeLE PCG35 Apo Apollo Lake Mini PC Review – Part 3: Ubuntu 17.10

I completed the review of MeLE PCG35 Apo with Windows 10 Home a few days ago, and as promised, I’ve now installed the freshly released Ubuntu 17.10 in the Intel Celeron J3455 “Apollo Lake” mini PC. I’ll start by shortly explaining the step to install Ubuntu 17.10 in the M.2 slot, although you could also install it to the internal eMMC flash replacing Windows 10, then show what works and what does, and finally include a video reproducing the tests I usually do in Windows 10. How to Install Linux in MeLE PCG35 Apo This partially follows the procedure I used to run (not install) Ubuntu 16.04 on MeLE PCG03 Apo mini PC. First you’ll need to download the ISO of your choice (ubuntu-17.10-desktop-am64.iso in my case), and prepare a bootable USB flash drive with the software of your choice be it Rufus, Startup Disk Creator or others. I did […]

RedRat-X IR, Bluetooth & RF4CE Box Can Control Multiple TVs and Set-top Boxes

IR blasters can be used to control multiple IR devices through infrared, or other interfaces, for example DVR can use such device to change the channel of a set-top box just before recording. RedRat-X is one of those devices for automating control of TVs, STBs and other infrared equipment, but it’s quite more versatile, as beside its built-in IR blaster, it adds 3 IR outputs were you can connect your own IR transmitters, as well as USB and Ethernet for remote controls. Furthermore, it can also take add-on modules to emulate  Bluetooth and RF4CE remote controls. RedRat-X specifications: IR blaster via the front of the unit. 0 mA to 250 mA in 100 steps. 3x plug-in IR jack sockets which can be used in two modes: Current mode (default): For use with plug-in IR flashers – 0mA to 100mA in 100 steps. Voltage mode: To interface to IR distributions systems, […]
