Raspberry Pi Suddenly Not Working? You May Have to Repair your microSD Card

Raspberry Pi Out of Order

Automatic updates are great because they keep your system up-to-date with the latest features and/or security fixes. That’s as long as the firmware is not messed up of course, as Bootlin and others found out when they discovered their Raspberry Pi board(s) had become inaccessible after an ill-fated Raspbian update. What happened is that raspi-copies-and-fills package, which implements optimized low-level memory functions for the ARM processor,  was updated on March 11th, and the update somehow made some programs completely fail to run. This explains why Bootlin guys were unable to access their Raspberry Pi over SSH. The fix is simple, as long as you have physical access to your Raspberry Pi’s micro SD card, remove it from the board, and insert it into your computer, and…: Repair the rootfs partition with Delete etc/ld.so.preload Unmount the micro SD card, and reinsert it into your Raspberry Pi board. If you’ve installed your Raspberry Pi in a hard to access location, it looks …

4Kopen UHD Video Development Platform Features STMicro STiH418 Media Processor

4Kopen

Back in 2016, I read news about STMicro exiting the set-top box chipset market, so I just assumed all their STiHxx processors would be phased out, and I was surprised to come across 4Kopen, described as an open 4K UHD video development platform powered by STMicro STiH418 media processor, especially it was just showcased at 2019 Integrated Systems Europe (ISE 2019) at the beginning of the month. The development board comes with 2 GB RAM, HDMI 2.0 output, HDMI 1.4 input, Gigabit Ethernet, USB 3.0, a mini PCIe slot fitted with an 802.11b/g/n WiFi module, an eSATA connector and more. 4Kopen (B2264) hardware specifications: SoC – STMicro STiH418 quad-core Arm Cortex-A9 processor @ 1.2 GHz,  quad-core Mali-400 GPU, and 4x ST231 DSP (Each Core Quad issue) @ 650 MHz System Memory – 2 GB DDR3 @ 2133 MHz Storage – micro SD socket, eSATA port Video & Audio I/O Output – HDMI 2.0 Tx up to 2160p60, 3.5mm AV jack …

Banana Pi to Launch a 24-Core Arm Server

Banana Pi 24-Core Arm Server

SinoVoIP has been offering Banana Pi single board computers for several years. Their boards are generally based on Arm processors, offered at a relatively decent price, although not as quite as good value as FriendlyELEC and Orange Pi ones. The company is also known for providing subpar documentation and firmware images, but a fairly active community still formed around their boards 🙂 The company has now demonstrated something a little different with a 24-core Arm server that should eventually be sold as a Banana Pi server board or actual server, as the full details are yet to be known. We did not get a glimpse at the actual hardware, but the blurry photo above gives some clues. We have 24-core Arm Cortex A53 processor with 32GB RAM (29.4GB seen by the OS) running Ubuntu 18.04.1 LTS with MATE desktop. There aren’t that many 24-core Arm Cortex A53 processors, so unless the company is using an announced processor, it has to …

CrowPi is a Portable Learning Kit for Raspberry Pi 3 B+ / Zero Boards (Crowdfunding)

Raspberry-Pi-Learning-Kit

We have an embarrassment of choices for Raspberry Pi accessories from touchscreen displays, HAT add-ons boards, sensors, breadboard, and so on, as well as good software and support from Raspberry Pi forums. This is all good, but it can be messy with all those jumper cables, and not really portable. Elecrow has a neat solution with the CrowPi learning kit for Raspberry Pi 3 and Raspberry Pi Zero that come with a 7″ display, several sensors, buttons, a breadboard, and more all packed in a small suitcase. Main parts of the kit: 7″ touchscreen display Breadboard with GPIOs status LEDs Input modules – Light sensor, IR receiver, PIR motion sensor, sound sensor, temperature & humidity sensor, touch sensor, ultrasonic sensor, NFC reader, and tilt sensor Output modules – 8×8 LED matrix, 4-digit LED display, I2C LCD1602 display, buzzer, vibration motor, relay module, 9G servo, and stepper motor. Control modules – 4×4 array keypad and direction keys (D-Pad) A battery is …
