CrowVision review – An 11.6-inch 1366×768 touchscreen display that works with multiple SBCs

CrowVision is an 11.6-inch IPS capacitive touchscreen display with 1366×768 resolution that is designed to work not only with the Raspberry Pi but most single board computers with mounting holes within a 100 x 80 mm rectangle. Elecrow sent me a sample so I’ll try it out with a Raspberry Pi, a Windows 11 mini PC, and a Ubuntu 22.04 laptop to make sure it works well with those operating systems. CrowVision unboxing The packages include the display module itself, a 12V/2A power adapter, USB Type-C and micro USB cables, an HDMI to mini HDMI cable, a micro HDMI to mini HDMI cable, two “ribbons” for cable management, a screwdriver, an OSD control board with five keys, and a user manual. The display does not come with an enclosure, so it’s better suited for DIY projects where users design their own enclosure or mounting solution. The control board is based […]

Snagboot is an open-source cross-vendor recovery tool for embedded targets

Bootlin has just released the Snagboot open-source recovery tool for embedded platforms designed to work with multiple vendors, and currently STMicro STM32MP1, Microchip SAMA5, NXP i.MX6/7/8, Texas Instruments AM335x and AM62x, and Allwinner “sunxi” processors are supported. Silicon vendors usually provide firmware flashing tools, some closed-source binaries, that only work with their hardware. So if you work on STM32MP1 you’d use STM32CubeProgrammer, while SAM-BA is the tool for Microchip processors, NXP i.MX SoC relies on UUU, and if you’ve ever worked on Allwinner processors you’re probably family with sunxi-fel. Bootlin aims to replace all those with the Snagboot recovery tool. The Python tool is comprised of two parts: snagrecover using vendor-specific ROM code mechanisms to initialize external RAM and run the bootloader (typically U-Boot) without modifying any non-volatile memories. snagflash communicates with the bootloader over USB to flash system images to non-volatile memories, using either DFU, USB Mass Storage, or […]

GL.iNet Spitz AX review – Part 2: a router with 5G NR, WiFi 6, 2.5GbE, failover and load balancing

Earlier this month I introduced the GL.iNet Spitz AX (aka GL-X3000NR) router with 2.5GbE, WiFi 6, and 5G NR cellular connectivity listing the specifications, doing an unboxing, and going through the initial setup. I’ve now received a new SIM card for testing and installed it into the router to continue the review. 4G/5G cellular connectivity on Spitz AX router After powering the router, the SIM card was detected and showed a 5G connection, but quickly fell back to 4G as can be seen with the cyan icon in the screenshot below. Shortly after, I lost 4G data connectivity, and after a while, the modem was not detected at all. But after restarting the router, and clicking on the “Auto Setup” icon everything looked to be working fine and I was always on a 5G connection from “house 1”. You’ll notice an envelop icon on the top right corner of the […]

Use Kea DHCP server as ISC DHCP server (dhcpd) is being phased out

The ISC DHCP server (dhcpd) was traditionally used to set up a DHCP server in Linux, but the software is reaching end-of-life, and the Internet Systems Consortium is now recommending their own Kea DHCP server or alternatives such as Dnsmasq or udhcpd (as found in Busybox) as a replacement. I was unaware of this having just used the isc-dhcp-server package to set up a DHCP server in NanoPi R6C router/mini PC earlier this month. But a blog post on Ubuntu informed us dhcpd was going away, and Canonical plans to switch over the Kea DHCP server instead. The main difference from the user perspective is that Kea relies on JSON configuration files so all your dhcpd files will have to be rewritten. Other highlights for the Kea DHCP server include: Modular component design, extensible with hooks modules. Kea includes daemons for a DHCPv4 server, a DHCPv6 server, and a dynamic […]
