DepthAI Brings AI plus Depth to the Raspberry Pi (Crowdfunding)

Edge computing on the Raspberry PI has been a bit of ups and downs, especially with everyone gearing for AI in everything. The Raspberry Pi, on its own, isn’t really capable of any reliable AI applications. Typical object detection on the Raspberry Pi would get you something around 1 – 2 fps depending on the nature of your model and this because all those processing is done on the CPU. To address this poor performance of AI applications on the Raspberry Pi, AI Accelerators came to the rescue. The Intel Neural Compute Stick 2 is one such accelerator capable of somewhere around 8 – 15 fps depending on your application. The NCS2, which is based on the Myriad X VPU technology, offers so much more than the compute stick delivers, and this is something that the team behind DepthAI has exploited to create a powerful AI module for edge computing […]

Fix for Raspberry Pi 4 4GB model’s USB Ports not Working on Ubuntu 19.10

Ubuntu 19.10 server was recently released with official support for Raspberry Pi 4 SBC. Shortly after I read stories about the USB ports not working on the board, but it took another interesting turn as Canonical now explains the bug only affects RPI 4 with 4GB RAM, and USB works just fine on boards with just 1/2GB RAM. The issue has been identified and it’s been found to be a kernel bug with a solution in the works that being tested. In the meantime, you can access to your Raspberry Pi 4 4GB USB ports by limiting the memory to 3GB in /boot/firmware/usercfg.txt as follows:

total_mem=3072

1	total_mem=3072

Alternatively here’s the link to an updated kernel provided by Hui Wang with you want to test it out: I built a testing kernel, not only includes the fix for USB host, but also includes all new patches from https://github.com/raspberrypi/linux.git rpi-5.3.y branch (about 107 […]

Digilent Offers 2 Zynq-Based Linux Development Boards Supporting SYZYGY Expansion

Digilent Announces SYZYGY high-speed SBCs Digilent has announced two new SBCs that are ultra-high-speed and built to be more modular than its other boards. The company, which has a great deal of experience in Pmod lower speed FPGA standards has now entered the open-source, SYZYGY high-speed standards with its Eclypse Z7 and the Genesys ZU development SBCs. Background on the Digilent Zybo FPGA SoC SBC We reported on the Zybo development board FPGA SoC from Digilent and that seems to have lead to the latest format for the Eclypse Z7. Zmod There is also a release planned for the new Zmod modules, built to work with both the Eclypse Z7 and the Genesys ZU as SYZYGY compliant expansion modules. Opal Kelly and Zmod expansion The Zmods are Opal Kelly module standard, called SYZYGY, first seen in the Opal Kelly SYZYGY Brain-1 SBC. The standard was developed to jump the gap […]

BOOTPRINT X2 96Boards AIoT Development Kit Features Sunrise 2.0 AI Processor

Horizon Robotics BOOTPRINT X2 is an AIoT / AI computing development kit providing a complete reference solution from device to cloud integration. The board is powered by the company’s Sunrise 2.0 AI edge processor based on the second-generation BPU (“Brain Processing Unit”) architecture that delivers up to 4 TOPS at low power consumption and is said to follow 96Boards specification, although from the photo below they’ve taken some liberties with the option (e.g. added a Gigabit Ethernet port). The board has now launched yet, and we have limited information about BOOTPRINT X2 kit specifications: SoC – Horizon Sunrise 2.0 AI edge processor with 4 TOPS equivalent AI processing power (no mention of architecture) System Memory – 1GB LPDDR4 RAM Storage – 4GB eMMC flash, MicroSD card socket Connectivity – Gigabit Ethernet Camera I/F – Dual 1080p camera inputs for symmetric binocular camera, combination of infrared and visible light. Audio – […]

Olimex OSHW Allwinner S3 IP Camera Board in the Works – Feedback & Suggestions Welcomed

Allwinner S3 Arm Cortex-A7 processor is designed for dual-camera systems and embeds 128MB RAM. It looks to be an evolution of the older Allwinner V3s chip that came with 64MB RAM and is software-compatible with the older camera SoC. We reported about the new processor and an Allwinner S3 development board last year, but Olimex has started working on an open-source hardware IP camera board based on the processor and is asking for feedback from customers and the community at large. Preliminary specifications: SoC – Allwinner S3 Cortex-A7 @ 1.2GHz with 128MB DDR3 RAM at 1333 MHz Storage -MicroSD card slot, configuration EEPROM, optional NAND/eMMC/SPI Flash on socket Camera I/F MIPI camera connector with RPi pinout Parallel CSI camera connector Display – LCD connector for LCD-OLinuXino 4.3″ to 15.6″ displays Audio – Audio in and out via 3.5mm audio jacks Connectivity Fast Ethernet with PoE option WiFi / BT module with […]

NanoPi M4V2 Kit Review – Part 2: FriendlyCore Desktop

We’ve already seen how to assemble NanoPi M4V2 metal case kit which offers an Arm mini PC solution with support for NVMe SSD. The new NanoPi M4V2 Rockchip RK3399 SBC is an evolution of the M4 board that brings faster LPDDR4 memory and adds power & recovery buttons. Since we’ve already tested several RK3399 SBC‘s and TV boxes, I planned to focus the review on thermal design evaluation (i.e. see how well the board cools), and see how memory bandwidth evolved from LPDDR3 to LPDDR4. I wanted to do so both with Linux and Android, since I could compare NanoPC-T4 (LPDDR3) benchmarks in Android. But this requires an eMMC flash module, and I don’t own any. So instead I planned to run Armbian because of support for armbian-monitor for nice temperature chart but it’s not working just yet, so instead I’ve done all tests with FriendlyCore Desktop (rk3399-sd-friendlydesktop-bionic-4.4-arm64-20190926.img) based on […]

Another GD32 RISC-V Development Kit with LCD By Seeed Studio

Recently we highlighted the $5 Longan Nano, a development kit released by Sipeed for the Gigadevice GD32V RISC-V family of microcontrollers. The Sipeed Longan Nano is powered by the GigaDevice’s GD32VF103CBT6, based on Nucleisys Bumblebee kernel (support RV32IMAC instruction sets and ECLIC rapid interrupt). Seeed Studio is currently on this quest for expanding the Gigadevice GD32V RISC-V ecosystem with the launch of the SeeedStudio GD32 RISC-V kit with LCD. The Seeed Studio development kit is based on the SeeedStudio GD32 RISC-V Dev Board and a 2.8 inch 240×320 pixel resistive LCD screen. The Seeed Studio GD32 RISC-V Dev Board is based on the 32-bit general-purpose GD32VF103VBT6 MCU, which can run at up to 108MHz. It comes with a 128KB on-chip Flash memory, and a 32KB SRAM memory. The development board comes with a total of 80 GPIOs, an onboard 8MB Flash and 256 Byte EEPROM, a staggering amount resources for this […]
