Linux 5.18 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 5.18 is out! Linus Torvalds has just announced the release on lkml: No unexpected nasty surprises this last week, so here we go with the 5.18 release right on schedule. That obviously means that the merge window for 5.19 will open tomorrow, and I already have a few pull requests pending. Thank you everybody. I’d still like people to run boring old plain 5.18 just to check, before we start with the excitement of all the new features for the merge window. The full shortlog for the last week is below, and nothing really odd stands out. The diffstat looks a bit funny – unusually we have parsic architecture patches being a big part of it due to some last-minute cache flushing fixes, but that is probably more indicative of everything else being pretty small. So outside of the parisc fixes, there’s random driver updates (mellanox mlx5 stands out, […]

Turing Pi 2 mini-ITX cluster board supports RK3588 based Turing RK1, Raspberry Pi CM4, and NVIDIA Jetson SoMs (Crowdfunding)

We first covered the Turing Pi V2 mini-ITX cluster board supporting up to four Raspberry Pi CM4 or NVIDIA Jetson SO-DIMM system-on-module in August 2021. The company has now launched the Turing Pi 2 on Kickstarter with a little surprise: the Turing RK1 module with Rockchip RK3588 Cortex-A76/A55 processor and up to 32GB RAM. The board allows you to mix and match modules (e.g. 3x RPi CM4 + 1x Jetson module as on the photo below), and with SATA ports, Gigabit Ethernet networking, USB 3.0 ports, mPCIe socket, you could build a fairly powerful homelab, learn Kubernetes, or self-host your own apps. Turing Pi 2 specifications: SoM interface – 4x 260-pin SO-DIMM slots for up to four Raspberry Pi CM4 with Broadcom quad-core Cortex-A72 processor, up to 8GB RAM, up to 32GB eMMC flash (adapter needed) NVIDIA Jetson Nano/TX2 NX/Xavier NX SO-DIMM system-on-modules with up to 6x Armv8 cores, and […]

Raspberry Pi Compute Module 4S SO-DIMM module is powered by Broadcom BCM2711 SoC

The Raspberry Pi Compute Module 4S is an upcoming system-on-module based on the same Broadcom BCM2711 quad-core Cortex-A72 processor found in Raspberry Pi Compute Module 4, but using the same SO-DIMM connector as found in earlier Raspberry Pi Compute Module boards, instead of the new board-to-board connectors. The Raspberry Pi Compute Module 4S is not launched yet, but we discovered it will be used on Revolution Pi S and SE series DIN-rail industrial computers via a tweet from Jeff Geerling and his post on Raspberry Pi forums. Apart from the faster processor and support for 4K video output, The Raspberry Pi Compute Module 4S is quite similar to the Raspberry Pi Compute Module 3+. Memory bandwidth might be a little better with the LPDDR4 memory too (TBC), but all the rest looks the same. The main advantage of the new Raspberry Pi CM4S module is compatibility with older SO-DIMM carrier […]

Add WiFi HaLow to Raspberry Pi with ALFA Network AHPI7292S HAT

ALFA Network AHPI7292S is a Raspberry Pi HAT with WiFi HaLow (802.11ah) offering low power connectivity, up to one kilometer line-of-sight range, and that’s mostly useful for security cameras, but it can also be used to extend the range of the network for other purposes. The Newracom NRC7292 expansion board adds to be few WiFi HaLow hardware we’ve seen in the past year including a mini PCIe card, a WiFi HaLow development board, and a gateway kit to extend the range of IP cameras. ALFA Network AHPI7292S specifications: Chipsets – Newracom NRC7292 WiFi HaLow SoC (IEEE 802.11ah draft 8.0 compliant) RF – Qorvo RFFM6901 front-end Frequencies – 847 MHz (TW), 866 MHz (EU), 915 MHz (US), 922 MHz (KR), 924 MHz (JP) Modulation – OFDM with BPSK, QPSK, 16QAM, 64QAM Data rate – 150 Kbps ~ 15 Mbps Channel bandwidth – 1/2/4 MHz Antenna connector – 1x IPEX/U.FL connector or […]

Kontron Pi-Tron CM4 mini PC leverages Raspberry Pi Compute Module 4 for industrial applications

Kontron Pi-Tron CM4 is a single-board computer and mini PC based on the Raspberry Pi Compute Module with a Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8GB RAM, up to 32GB eMMC flash, HDMI video output, two Ethernet ports, optional WiFi and Bluetooth connectivity, and an M.2 slot for AI or wireless expansion. Designed for industrial applications, the Pi-Tron CM4 is also equipped with RS232, RS485/CAN FD bus, and GPIO terminal blocks, supports 24V input voltage, and is optionally sold as AL Pi-Tron CM4 in a housing suited for challenging environments.
