Tribulations with Linux on Zidoo M6 Rockchip RK3566 mini PC

After our review of the Zidoo M6 mini PC with Android 11, we’ve installed Linux on the Rockchip device, and we did boot to a Linux Qt user interface built with buildroot. Let’s try to see what we can do with the image, and then try Ubuntu from a competing mini PC to check out if that can work. Since there’s no package manager to install a screenshooting program, I tried to use the usual method to take a framebuffer screenshot.

cat /dev/fb0 > screen.raw

1	cat /dev/fb0 > screen.raw

It generated an 8MB file which looked good, but the content was just comprised of zeros.

I asked Zidoo for a method to take screenshots in their Linux image, but I was told there weren’t any at this time… No worries, let’s try some of the applications in the Qt interface starting with the Multivideoplayer: It starts well with 9 videos of Big Buck Bunny playing simultaneously, […]

Android 12 for TV released for ADT-3 Developer Kit

While Android 12 images and related AOSP source code were released in October, it took a bit longer for Android 12 for TV. But the latest version of Android for larger screens has apparently been released yesterday on the developer website with Android 12 for TV now available, albeit only for the ADT-3 Developer Kit based on the Amlogic S905Y2 processor. Google says they’ve improved the user experience and compatibility on TV devices with media playback improvements, a refined user interface, enhanced privacy and security, as well as better support for HDMI and TV tuners. Highlights of the Android 12 for TV release include: User Interface Background blurs using RenderEffect and in WindowManager 4K UI support (CNXSoft: up to now most devices were using a 1920×1080 user interface (framebuffer), and play 4K video on another hardware video buffer) Accessibility settings for font sizes Media improvements Automatic refresh rate switching to […]

Download a free trial of the SoftNeuro Deep Learning SDK for Intel and Arm targets (Sponsored)

Jetson Xavier Tensorflow Lite vs SoftNeuro

Morpho, a global research & development company established in Japan in 2004 and specialized in imaging technology, is now offering a free trial for the SoftNeuro deep learning SDK working on Intel processors with AVX2 SIMD extensions, 64-bit Arm targets, while also leveraging OpenCL and/or CUDA. Some of the advantages of SoftNeuro are that the framework is easy to use even for those without any knowledge about deep learning, it’s fast thanks to the separation of the layers and their execution patterns, and it can run on several different hardware and OS being cross-platform. SoftNeuro relies on its own storage format (DNN format) to deliver the above advantages. But you can still use models trained with any mainstream deep learning framework. TensorFlow and Keras models can be directly converted to the DNN format, while models from other frameworks can be converted first to the ONNX format and then to the […]

Raspberry Pi 4 PLC Industrial controller targets IIoT applications

I’ve just noticed Boot&Work Corp was now offering an “Industrial Shields” branded PLC industrial computer powered by Raspberry Pi 4 SBC. We previously covered the company in 2017 at a time when they provided Arduino-based PLC modules optionally controlled with 10.1-inch panel PCs based on ARM Linux SBCs such as Raspberry Pi or Banana Pi. The “Raspberry Pi PLC Industrial Controller” is offered with either optoisolated outputs or relay outputs, and optional GPRS connectivity. The Linux PLC is equipped with up to 36 digital inputs, 16 analog inputs, 8 analog outputs, and 6 interrupts, as well as communication interfaces such as CAN bus, up to 2x Ethernet ports, dual RS-485, WiFi, and Bluetooth. Raspberry Pi PLC Industrial Controller basic specifications: Single board computer – Raspberry Pi 4 SBC with 2GB to 8GB RAM, WiFi 5, and Bluetooth 5.0 connectivity Storage – 8GB MicroSD card Video Output – 2x Micro HDMI […]

Octo4a app installs OctoPrint server on Android smartphones

Octoprint is a popular open-source 3D printer controller software that runs on Raspberry Pi boards, Orange Pi Lite SBC, Amlogic TV boxes, and other devices. But considering many people may already an older, perfectly working smartphones at home, FeelFree (Filip) decided to create the Octo4a project that install an Octoprint server on Android smartphones. It makes perfect sense since many smartphones come with a USB OTG interface that can connect to the 3D printer for control, while the touchscreen display is used for the user interface, and the camera to monitor your prints. SSH could be used to access the phone Octoprint server and change the settings manually. You can access the source code and APK files on Github. You’ll need to enable third-party apps in the settings before installing the app in order to install Octoprint on the phone. The only required permission is storage, except if you’d like […]
