NXP i.MX RT106F & RT106A/L Cortex-M7 Processors Target Offline Face Recognition & Smart Audio Applications

NXP i.MX RT crossover processors combine real-time capabilities of microcontrollers with the performance of application processors thanks to an Arm Cortex-M7 core clocked at 528 MHz and more. The performance is indeed impressive as shown by Teensy 4.0 benchmarks, but so far NXP i.MX RT processor targeted general purpose applications. The company has now introduced three new crossover processors designed for AI applications. NXP i.MX RT106F is designed for offline face recognition and expression Identification, while RT106L and RT106A are made for local and cloud-based embedded voice applications. NXP i.MX RT106F Processor Highlights of the processor: CPU – Arm Cortex-M7 @ 600 MHz (3020 CoreMark/1284 DMIPS) Memory – 1 MB On-Chip SRAM plus up to 512 KB configurable as Tightly Coupled Memory (TCM) External memory interface options – NAND, eMMC, QuadSPI NOR Flash, and Parallel NOR Flash Real-time, low-latency response as low as 20 ns Industry’s lowest dynamic power with […]

FriendlyELEC ZeroPi is a Tiny Allwinner H3 SBC with Gigabit Ethernet & USB, an Optional SPI Flash

Several years ago, FriendlyELEC launched NanoPi NEO board with Allwinner H3 quad-core Cortex-A7 processor followed by NanoPi NEO2 upgrading to the Allwinner H5 64-bit Arm Cortex-A53 processor. Both boards target low-cost headless applications with I/O headers, USB and Ethernet, but while the NEO2 comes with Gigabit Ethernet, NEO SBC only features 10/100M Ethernet. The company has now been working on a new family of boards called ZeroPi that’s very similar to NanoPi NEO boards, but they do not come with any I/O headers, and the first ZeroPi board features Allwinner H3 processor, and Gigabit Ethernet. ZeroPi specifications with highlights in bold or stricken-through showing differences against NanoPi NEO: SoC – Allwinner H3 quad-core Cortex A7 @ 1.2 GHz with an Arm Mali-400MP2 GPU System Memory – 256 or 512 MB DDR3 Storage – MicroSD card slot, unmounted SPI flash Connectivity – Gigabit Ethernet via Realtek RTL8211E PHY USB – 1x […]

Khadas VIM3L SBC up for pre-order for $50 and up, VIM1 & VIM2 Price Reduced

Shenzhen Wesion recently unveiled Khadas VIM3L SBC designed for HTPC / media center use cases. The board is based on Khadas VIM3 PCB but replaces the powerful Amlogic A311D processor by Amlogic S905D3 processor that should be just as good for video playback, but enable much cheaper hardware. Khadas VIM3L Pre-orders The board is not quite available yet, but the company has started to take pre-orders for Khadas VIM3L at discounted prices either as a bare board with Android 9.0 pre-installed ($49.99), or as a CoreELEC HTPC kit with enclosure, heatsink, WiFi antennas, and IR remote control ($69.99). Both feature Amlogic S905D3 quad-core Cortex-A55 processor coupled with 2GB LPDDR4(X) RAM, 16GB eMMC flash, and support 4Kp60 video output and playback with HDR support. Prices will increase with time as follows: September 3-16 (Early Bird) – $49.99 and $69.99 for the board and HTPC kit respectively September 17 – October 7 […]

Huawei Releases their Open Source Ark Compiler for HarmonyOS

Back in May, there were rumors Huawei was working on HongMeng OS as an alternative to Android mobile operating systems, as the OS was brought to light due to US sanctions against the company. The new operating system was later confirmed and will be called HarmonyOS outside of China. A few days ago I received a tip in Chinese with this link explaining Huawei had released the open-source Ark compiler for HarmonyOS aka OpenArkCompiler. The compiler works with Java apps and converts the source into AArch64 binaries. The illustration below implies it should also work with C, C++, JavaScript, and Kotlin programming languages. Three links were shared in the announcement: The official website – https://www.openarkcompiler.cn/home The code hosting website – https://code.opensource.huaweicloud.com/openarkcompiler/openarkcompiler/home A mirror for the code – https://gitee.com/harmonyos/OpenArkCompiler As a side note, I had never heard about Gitee, and the site is an alternative to Github in China, which may […]

Khadas VIM3 Linux Benchmarks and Comparison to Raspberry Pi 4

I received Khadas VIM3 Amlogic A311D SBC in early July and started testing it with Android running some benchmarks and playing games last month. I was impressed by graphics performance and overall benchmark results in Android, especially the results I got with a heatsink matched Khadas own results with heatsink + fan. So I installed the latest Ubuntu 18.04 available at the time (July 19) in order to repeat benchmarks in Linux and see how it goes. System info in Ubuntu 18.04:

I decided to install armbianmonitor to draw some nice temperature charts as I did with Raspberry Pi 4:

wget https://github.com/armbian/build/raw/master/packages/bsp/common/usr/bin/armbianmonitor
sudo cp armbianmonitor /usr/bin/
sudo chmod +x /usr/bin/armbianmonitor
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2C0D3C0F
sudo wget http://goo.gl/vewCLL -O /etc/apt/sources.list.d/rpimonitor.list
sudo armbianmonitor -r

wget https://github.com/armbian/build/raw/master/packages/bsp/common/usr/bin/armbianmonitor

sudo cp armbianmonitor /usr/bin/

sudo chmod +x /usr/bin/armbianmonitor

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2C0D3C0F

sudo wget http://goo.gl/vewCLL -O /etc/apt/sources.list.d/rpimonitor.list

sudo armbianmonitor -r

But I had some error during installation:

sudo armbianmonitor -r
Installing RPi-Monitor. This can take up to 5 minutes. Be patient please/usr/bin/armbianmonitor: line 189: /etc/armbian-release: No such file or directory

Now you're able to enjoy RPi-Monitor at http://192.168.1.8:8888

sudo armbianmonitor -r

Installing RPi-Monitor. This can take up to 5 minutes. Be patient please/usr/bin/armbianmonitor: line 189: /etc/armbian-release: No such file or directory

Now you're able to enjoy RPi-Monitor at http://192.168.1.8:8888

And while I can load the webpage with top menu appearing, it won’t show any data, as its name implies it may only work in Armbian. SBC Bench on Khadas VIM3 Let’s download SBC bench:

How to Sandbox an arm64 GCC on aarch64 Hardware with armv7 Userspace

CNXSoft: Guest post by Blu about setting up arm64 toolchain on 64-bit Arm hardware running a 32-bit Arm (Armv7) rootfs. Life is short and industry progress is never fast enough in areas we care about. That’s an observation most of us are familiar with. One would think that by now most aarch64 desktops would be running arm64 environments, with multi-arch support when needed. Alas, as of late 2019, chromeOS on aarch64 is still shipping an aarch64 kernel and an armhf userspace. And despite the fine job by the good folks at chromebrew, an aarch64 chromeOS machine in dev mode ‒ an otherwise excellent road-warrior ride, is stuck with 32-bit armhf. Is that a problem, some may ask? Yes, it is ‒ aarch64 is the objectively better arm ISA outside of MCUs, from gen-purpose code to all kinds of ISA extensions, SIMD in particular. That shows in contemporary compiler support and […]
