Software configuration tips for Raspberry Pi clusters & parallel-ssh command

parallel-ssh

I missed that linux.conf.au 2021 took place on January 23-25 2021, and while browsing the schedule I noticed a talk entitled “Building Raspberry Pi Supercomputers” by Federico Lucifredi, Product Management Director for Ceph Storage at Red Hat. In the talk, he mostly focuses on the software part, and besides some basic steps, I learned about some new commands that be useful to people managing clusters of Raspberry Pi or other Linux boards or hosts. Configuring a cluster He used Picocluster image in his example, but for people wanting to use 64-bit OS, he recommends Ubuntu or Fedora images until Raspberry Pi OS 64-bit becomes stable. The first part of the configuration is making sure all the main user is the same on all board, disable SSH for root, and configure run levels (X not needed on clusters). Networking is configured with fixed IP addresses for Ethernet, and DHCP for WiFi. […]

SolidRun CuBox-M 2-inch Arm Linux/Android mini PC packs a 2.3 TOPS AI accelerator

CuBox-M i.MX 8M Plus Mini PC

Geniatech RK3568 Development Board to support Android 11 and Linux

RK3568 development board

RK3566 and RK3568 are the latest AIoT processors from Rockchip equipped with four Arm Cortex-A55 cores, a Mali-G52 GPU, and an impressive range of peripherals that make them suitable for all sorts of applications including AI edge computing and network video recorder (NVR). We already know Pine64 is working on Quartz64 SBC based on Rockchip RK3566, but I’ve just noticed Geniatech’s “RK3568 development board” that should offer even more features since the processor comes with extra I/Os compared to its little brother. Let’s have a look. Geniatech RK3568 development board specifications: SoC – Rockchip RK3568 quad-core Cortex-A55 processor up to 2.0 GHz with Arm Mali-G52 GPU supporting OpenGL ES 1.1/2.0/3.2, OpenCL 2.0, Vulkan 1.1, 0.8 TOPS NPU for AI acceleration System Memory – Up to 4 GB LPDDR4 Storage – Up to 128 GB eMMC 5.1 flash, 1x SATA 3.0 port, MicroSD card slot, M.2 socket for NVMe SSD (See […]

Jetson AGX Xavier based Edge AI Platform supports 8 GMSL automotive cameras and 10Gbps Ethernet

Jetson Xavier AI Edge computer with 8 GSML cameras

Neousys Technology, a Taiwan-based provider of rugged embedded systems, has introduced the NRU-110V Edge AI inference platform powered by an  NVIDIA Jetson AGX Xavier SoM. It comes with eight FAKRA Z connectors to support up to eight GMSL automotive cameras, as well as one 10GbE (10 Gigabit Ethernet) port for real-time video data transfer. The system specifically supports GMSL cameras with 3-exposure HDR, LED flicker mitigation, good light-sensitivity, and IP67 waterproof characteristics,  and also comes with a synchronize mechanism to simultaneously capture high-quality images from 8 GMSL cameras while accepting GPS PPS signal to align image data with other sensors. That makes it suitable for various applications ranging from autonomous driving, mobile robots, precision agriculture, intelligent V2X, to teleoperation. Neousys NRU-110V specifications: System-on-Module – NVIDIA Jetson AGX Xavier SoM with SoC NVIDIA 512-core Volta GPU 8-core Arm Carmel CPU 2x NVDLA Engines 7-Way VLIW Vision Processor Memory – 32GB LPDDR4x […]

PICO-PI-IMX7 NXP i.MX7 SBC offered for under $20 (Promo)

Cheap iMX7 SBC

TechNexion PICO-Pi-IMX7 single board computer was introduced a few years ago with an NXP i.MX 7Solo or 7Dual Cortex-A7 Intel Edison compatible CPU module, in a form factor similar to Raspberry Pi 3, and supported by Android Things that was still a thing at the time… It looks like Arrow Electronics is trying to get rid of some stock, as the company is selling the Amazon version of the PICO-PI-IMX7 board for $19.58 including free shipping for ArrowPerks members, instead of the usual $120+ price tag. We had written about the PICO-iMX6 module and PICO-PI-iMX8 SBC previously, but never about the i.MX7 version, nor the PICO-PI-IMX7 board, so let’s have a closer look at what the board has to offer. PICO-Pi-IMX7 specifications: PICO-iMX7 system-on-module SoC – NXP i.MX 7Dual dual-core Cortex-A7 processor @ 1 GHz with Cortex-M4 real-time core System Memory – 512MB DDR3L Storage – 4GB eMMC flash Connectivity […]

FOSDEM 2021 Online February 6-7 – Hardware, Embedded & IoT talks

FOSDEM 2021 Online

FOSDEM is an open-source developer event that takes place on the first week-end of February every year in Brussels, Belgium. Every year except this year, as due to COVID-19 restrictions, FOSDEM 2021 will take place online like most events these days. The schedule has been up for some time, and today I’ll look at some of the interesting talks mostly from the Embedded, Mobile and Automotive “virtual devroom” but also other tracks. Saturday, February 6, 2021 13:00 – 14:00 – From Reset Vector to Kernel – Navigating the ARM Matryoshka Long gone are the times of executing the OS in-place from memory-mapped flash upon reset. A modern SoC now comes with complex mask ROM firmware, with driver, filesystem, protocol and crypto support for loading… yet another bootloader. In his talk, Ahmad follows this chain of bootloaders until the kernel is started, stopping along the way for RAM setup, peripherial initialization, […]
