    Pick Your (Memory) Poison

    New Zephyr RTOS Cookbook from Roy Jamil and Ayoub Bersheela (AC6), now on Amazon in print and e-book Git 2.55: one-step commit fixups, auto-stash on checkout, and remote groups for fetch and push Linux kernel debating the Assisted-by: tag Address Sanitizer memory poisoning to catch use-after-free, buffer overflows, and unallocated access Lightweight heap write sanitizer for sys_heap rpmsgfs filesystem for mounting remote-core directories over RPMsg MAINTAINERS file "deferral" so driver changes reach the actual driver maintainer, not just the subsystem owner Revamped tracing sample with cross-OS terminal viewer rendering traces on the fly Hall-effect flow meter driver STG-800 lococube mini-PLC (24 V, CAN, and a rugged enclosure) FeatherWing MAX3421E shield (USB host and device over SPI) XIAO nRF54LM20A MIMXRT685-AUD-EVK, an audio-focused NXP crossover MCU with HiFi DSP RA8P1 Titan: a Cortex-M85 beast with dual gigabit Ethernet, MIPI DSI/CSI, and a Raspberry-Pi-style header Check out Zephyr Tech Talk next week (https://github.com/golioth/pouch) Join us on Discord! // #podcast at https://chat.zephyrproject.org

    The "K" That Saved 30K

    snprintk() vs. snprintf()  Linux 7.2 drops strncpy() Steam Machine teardown, and another kite spotted inside SPDX 3 SBOM support lands in Zephyr, a day before it merged in the Linux kernel. Web-based SPDX 3 visualization tool, for browsing the dependency graph, sources, licenses, ... from your SBOM. Standalone UF2 USB MSC bootloader Where double-tap reset actually came from (Arduino, around April 2015, on a SAMD21 board) Ghost edge AI sticker, a flexible nRF54L15 PCB with vibration and temperature sensing GigaDevice ramping up their Zephyr efforts Twister post-build checks flag stray Git repos pulled in during CI A WCH QingKe Debug Module console driver, single-pin printf-style logging in the spirit of Arm SWO scoped_guard() and scoped_cond_guard(), Python-with-style auto-releasing locks for C ZMS' interactive storage calculators UDP logging backend for coredump MikroElektronika Two Wire ETH Click, a tiny 10BASE-T1S single-pair Ethernet shield Four new ST B-M2MEM-PACK1 M.2 memory packs, hexa/octa-SPI flash and RAM on an M.2-style connector TI AM243x-EVM, Sitara with dual R5 clusters, a Cortex-M4, gigabit Ethernet, EtherCAT, and PCIe One last nudge to fill out the Zephyr Developer Survey before it closes!
