The screens that show the previews of photos taken on rides at Chessington appear to be running Linux not Windows. I’m impressed!

nmcli is growing on me
A public admission, as I learn to use it for the things I need, Network Manager via NMCI is growing on me. Posting notes publcially;

nmcli connection modify "Wired connection 1" -ipv4.addresses "192.168.98.17/28"

nmcli connection modify "Wired connection 1" +ipv4.addresses "192.168.42.17/28" nmcli connection modify "Wired connection 1" 802-3-ethernet.cloned-mac-address 9e:a8:d4:e4:24:42 ; sync ; reboot

I've been working on improving the rudimentary support for firmware update deltas that has existed in NervesHub for a long time. There are some PRs still in flight but the support is becoming less rudimentary by the day :)

Given that I want to target i486 with @OS1337 but don't want to deal with obsolete hardware that is dying of old age, I think it's more fitting to consider a sort-of mainboard to shove some 486SX-SOM with PC/104-Plus on and have the few necessities hooked up to it. Maybe even put it inside a THINN #Pizzabox-style #case?

It would also make a new "bridge" machine to interface old PCI & ISA hardware and allow connecting i.e. a #QuadFlop and roll with that...

Taming Hard Faults in Zephyr OS: Практическое руководство для embedded-разработчиков

🚨 Что такое Hard Fault простыми словами Hard Fault — это критическая ошибка процессора. Проще говоря, это ситуация, когда микроконтроллер встречает что-то настолько «невозможное» для себя, что не может продолжить выполнение программы. Типичный пример — попытка обратиться к памяти, которой не существует, или выполнение запрещённой инструкции. Когда это происходит, процессор сразу передаёт управление специальному обработчику — Hard Fault Handler .

I feel like I have superpowers because I got an STM32F103C8 to be a usb device and blink an led omg #stm32 #embassy #rust #embedded

Spent two evenings debugging a UART overrun in embassy-rs, diving deep into ring buffers, interrupts, and clock configs…

Turns out the real bug was me running a debug build. The issue doesn’t exist in release. 🤦‍♂️

Spinlock vs. Mutex vs. Semaphore: Разбираемся в синхронизации с Zephyr OS

Всем привет! Сегодня хочу углубиться в одну из самых важных тем в мире Zephyr OS — синхронизацию потоков и задач. Если вы хоть раз работали с k_thread_create , гоняли потоки туда-сюда и ловили bus fault, вы меня понимаете. Когда задача одна — всё просто. Но как только вырастает многопоточность, задачи начинают драться за общий ресурс — и тут без надёжной синхронизации не обойтись. У Zephyr OS есть три главных инструмента для этого: spinlock , mutex и semaphore . Каждый со своим характером и подводными камнями.

bmputil V1.0.0-rc.2 is here! This release candidate is quite a big change from rc.1 because we realized that we need to address the command line interface structure before the V1.0 release. See release notes for details. Please give it a try and let us know if you have any suggestions or questions! 🎉 Massive thanks to @dragonmux for making this release a reality! https://github.com/blackmagic-debug/bmputil/releases/tag/v1.0.0-rc.2 #opensource #rust #embedded #electronics #debugging #microcontrollers #jtag #swd

there are already teardowns of Switch 2 and charging dockers

looks like Nintendo ordered custom USB input port controller chips from Infineon/Cypress - CP10356AT/CP10358AT/CP10359AT - to handle the execution of USB authentication process handshake for charging - and possibly other restrictions - with STM32 MCU running the "show"
