Armbian v25.2 and DietPi v9.11 released with updated Ubuntu and Debian-based Linux images for single board computers

Vendor-provided Linux images for single board computers are not always working optimally, so this post is a regular reminder that users may want to check out Armbian and DietPi projects mostly supported by the community but also backed by some of the vendors who offload some (repackaging) software work to them. Armbian and DietPi are separate projects, but this month, Armbian v25.2 and DietPi v9.11 were almost released simultaneously. I don’t report on each release (should I?), but they release an update every few months. The last time we had a look at both projects was in September 2024 for the releases of DietPi 9.7 and Armbian 24.8. Let’s see what the new releases have to bring. Armbian v25.2 Main changes: New Boards – Rock 2A and 2F, NanoPi R3S, Retroid Pocket RP5, RPMini, Rock 5T, GenBook, MKS-PI, SKIPR, Armsom CM5, NextThing C.H.I.P, Magicsee C400 Plus Rockchip 3588 Improvements – […]

OpenWrt 24.10 released with Linux 6.6, TLS 1.3 by default, and 1970 supported devices

OpenWrt 24.10 open-source lightweight Linux operating system for routers has just been released. It’s been upgraded to Linux 6.6 from Linux 5.15 in OpenWrt 2023.05, supports TLS 1.3 by default, improves support for WiFi 6 (802.11ax), and adds initial support for WiFi 7 (802.11be). After over one year of work since the release of OpenWrt 23.05, OpenWrt 24.10 adds over 5400 commits, and the total number of supported devices is now close to 2,000 at 1,970. It’s also the first stable release supporting OpenWrt One, the router directly designed by OpenWrt developers in collaboration with Banana Pi. OpenWrt 24.10 highlights: TLS 1.3 support in default images with MbedTLS 3.6 Activate POSIX Access Control Lists and file system security attributes for all file systems on devices with big flash sizes. Needed by docker. Note this is not enabled for all targets with the small_flash feature flag, including ath79/tiny, bcm47xx/legacy, lantiq/ase, lantiq/xrx200_legacy, […]

Ceva-Waves Links200 IP supports Bluetooth LE High Data Throughput (HDT) up to 7.5 Mbps, 802.15.4 for Zigbee, Thread and Matter

Ceva has recently unveiled the Ceva-Waves Links200 multi-protocol platform IP with support for Bluetooth LE High Data Throughput (HDT) technology up to 7.5 Mbps and IEEE 802.15.4 for Zigbee, Thread, and Matter designed for TSMC’s low-power 12nm process. Released in 2016, Bluetooth 5 upgraded Low Energy implementation with four times the range and twice the speed of Bluetooth 4.0 LE transmission which meant up to 2 Mbps over BLE, and even the latest Bluetooth 6.0 specification does not change that. There’s just a new LE 2M 2BT physical layer for Bluetooth Channel Sounding. So I was intrigued when the press release of the Links200 further read: Addressing the rising market demand for faster, more efficient Bluetooth connectivity, particularly for low-power audio and latency-sensitive IoT applications, the breakthrough High Data Throughput mode more than doubles the speed of traditional Bluetooth, delivering a data rate of up to 7.5 Mbps. For this […]

NXP EdgeLock A30 Secure Authenticator chip enables battery authentication for compliance with EU regulation 2023/1542

NXP recently launched the EdgeLock A30 Secure Authenticator chip, a Common Criteria EAL 6+ certified secure authentication designed for IoT devices, including battery authentication applications. It complies with the EU’s Batteries Regulation 2023/1542, which mandates the inclusion of a Digital Product Passport (DPP), by 2027 to ensure traceability, sustainability, and safety in battery manufacturing and recycling. Alasdair Ross, Senior Director, NFC IoT Security, NXP explains: Secure authentication helps to ensure brand protection, consumer safety, and product traceability, fostering trust and shielding devices from physical damage. Smaller than a grain of rice, the EdgeLock A30 is designed to fit into even the smallest of devices. It supports multiple authentication use cases, making it easier for developers to support a variety of devices and accessories with a single solution, including device to device, cloud to device, counterfeit protection, and storage or protection of device identity. To address these requirements NXP’s EdgeLock A30 […]

Linux 6.13 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.13 on the Linux Kernel Mailing List: So nothing horrible or unexpected happened last week, so I’ve tagged and pushed out the final 6.13 release. It’s mostly some final driver fixes (gpu and networking dominating – normal), with some doc updates too. And various little stuff all over. The shortlog is appended for people who want to see the details (and, as always, it’s just the shortlog for the last week, the full 6.13 log is obviously much too big). With this, the merge window for 6.14 will obviously open tomorrow. I already have two dozen pull requests pending – thank you, you know who you are. Linus Release about two months ago, Linux 6.12 – the new LTS version – brought us real-time “PREEMPT_RT” support that had always required out-of-tree patchsets until now, the completion of the EEVDF (Earliest Eligible […]

Imagination exits the RISC-V CPU market

Imagination Technologies has decided to exit the RISC-V CPU market to redirect its resources to the development of its GPU and AI products. This was reported by eeNews Europe following an interview with the company: Imagination exited its standalone line of CPUs to increase our investment in graphics, AI and compute at the edge which we believe is transformational for our business […] We remain committed to the RISC-V ecosystem and believe this change to our business allows us to partner more easily with the wider ecosystem as providers of the GPU of choice for RISC-V The company announced its entry into RISC-V IP core in 2021 with the introduction of the Catapult 32-bit and 64-bit RISC-V CPU cores, followed by the 32-bit RTXM-2200 real-time core in 2022, and the cost-optimized APXM-6200 RISC-V core was introduced last year. But all those RISC-V CPU cores are gone and won’t be found […]
