“Опять всё распилили?” Мифы, боль и реальная экономика российской микроэлектроники

Иван Лебедев (“Элрон”) о российской ЭКБ и ее будущем Интервью с генеральным директором “Элрон” о российской микроэлектронике, электронной компонентной базе, импортозамещении и RISC-V. На каналах “КЕДР Солюшенс” вышел 9-й выпуск подкаста “Платы и байты”. Публикуем ключевые темы и идеи разговора для тех, кто предпочитает читать. Гостем Егора Гуторова в этот раз стал Иван Лебедев, генеральный директор компании “Элрон”. Говорили о том, как компания прошла путь от контрактного разработчика до производителя собственных продуктов. Обсудили, как изменилось отношение потребителей к российской электронике и какое будущее ждет отрасль.

Have now got to a state where I can start the build of Google's #V8 JavaScript interpreter outside #NodeJS on #RISCV ... Took a while to get a valid toolchain and configuration in place here but it's now shugging away and is about 10% of the way through (Running under Ubuntu 25.10 for "reasons" in a qemu container on my x64 laptop...)

Have taken laptop out of it's usual lower power mode and will leave it running overnight. Hopefully it'll be done by morning.

В заголовке моего ELF есть точка входа. Оказалось, её никто не читает

Три статьи я собирал файл и отдавал его эмулятору, ни разу в него не заглянув. Заглянул. Внутри два разных описания одних и тех же байтов, ответ на вопрос, откуда взялся адрес 0x80000000, и поле, которое я заполнял зря. Ну, открываем!

While I'm on a roll I would like a #Swype style keyboard for #Sailfish and on-device voice dictation would be nice but neither was available last time I checked.

Hardware wise I can now cope ok without fingerprint scanner or NFC on the #JollaC2 - minor inconveniences not to have them.

Oh and if #Jolla's next handset was #RISCV that would be great too although that might be limiting for apps, both under #AppSupport and in the Jolla app store I guess. I can dream...

I'm very VERY VERY interested in RISC-V microcontrollers. If any of you have any inforamtion or where to begin plase do send me a message

I've got now five ESP32 boards and I've never been happier EXCEPT when I notice they uuse Xtensa and not Risc-V

Моя рекурсия зависла навсегда, и это был правильный результат

Написал рекурсию тем же приёмом, что во второй статье, и программа повисла навсегда: возвращаться ей было некуда. Чиню, завожу стек и по дороге выясняю, что регистра sp в наборе команд нет вовсе. А потом урезаю стек до 128 байт, и сборка об этом не говорит ни слова. Ломать второй раз!

Мой код терял бы 230 байт из 231. Чтобы это увидеть, пришлось патчить QEMU

Через четыре часа после первой статьи пришёл комментарий: в моём коде не хватает трёх инструкций, и на настоящей плате он рассыплется. Читатель arteast был прав. Сел воспроизводить поломку. Собрал два варианта, свой и правильный, прогнал на строке в 231 байт. Вывод побайтово одинаковый. Замедлил линию до предела. Ничего не изменилось. Написал программу, которая смотрит, бывает ли передатчик занят хоть когда-нибудь. При выводе в консоль не бывает. Моя ошибка внутри эмулятора не проявляется вообще. Проверить себя было нечем. Пришлось чинить эмулятор. Ну, чини!

🚩 NetBSD 11.0 a fost lansat: Suport nativ pentru RISC-V și compatibilitate îmbunătățită cu Linux!

Noul update major al istoricului sistem de operare din familia BSD, NetBSD 11.0, este acum disponibil oficial, aducând îmbunătățiri remarcabile pe partea de suport hardware, performanță și securitate.

✨ Ce aduce nou NetBSD 11.0:

🏗️ Arhitectură RISC-V extinsă:
• Suport complet și îmbunătățit pentru hardware-ul bazat pe arhitectura deschisă RISC-V (atât pe 64 de biți, cât și pe 32 de biți), extinzând portabilitatea legendară a sistemului.

🐧 Compatibilitate mai bună cu pachetele Linux:
• Stratul de compatibilitate COMPAT_LINUX a primit actualizări majore, permițând rularea mai multor aplicații și utilitare native de Linux pe un kernel NetBSD.

⚡ Drivere și stivă grafică modernizate:
• Drivere grafice actualizate pentru procesoarele grafice moderne Intel, AMD și NVIDIA, oferind suport mai bun pentru accelerarea 3D și monitoare de înaltă rezoluție.

🔒 Măsuri avansate de securitate:
• Îmbunătățiri la nivelul kernelului pentru prevenirea exploatării vulnerabilităților de memorie (ASLR extins, măsuri mai severe de izolare a proceselor).

🛠️ Sistem de fișiere și rețea:
• Optimizări de performanță pentru FFS (Fast File System) și ZFS, alături de îmbunătățiri ale stack-ului de rețea IPv4/IPv6.

Conform celebrului lor motto "Of course it runs NetBSD", noua versiune demonstrează încă o dată flexibilitatea incredibilă a acestui sistem de operare! 🚀

I've managed to build GNU Guix from source on Milk-V Jupyter RISC-V machine:
https://codeberg.org/guix/guix/issues/9898#issuecomment-20414228

The next step is to actually run Guix and check if "guix pull", "guix upgrade", "guix install" etc. work fine.

Двенадцать символов, двадцать один байт: как я научил голый RISC-V говорить «Привет, мир!»

Без библиотек, без обвязок, без операционной системы под ногами. Реальный код на реальном железе — ну, почти реальном. Пустая эмулируемая машина RISC-V, десяток строк ассемблера, и в терминале: Сначала думал вывести «hello», как все. Пусть будет «Привет, мир!» Ну, привет!

A follow up to this as someone on Bluesky pointed me to an article which mentions a GCC toolchain that might allow llama.cpp with the IME2 extensions for the SpacemiT-K3 to be built from source instead of using the Bianbu binaries.

Gave up trying to run #opencode locally on the #RISCV box - far too slow under qemu. I've now tried it in WSL on my Windows/Arm laptop connected to the llama.cpp+qwen2.5 instance on the RISC-V K3 system and quite pleased with the results. Generated a basic piece of code fairly quickly. Definitely usable. Will be interesting to see how it copes with more complex queries.

Currently using the 3b version of the model but may try the 8b one too to see how it works - (when machine is otherwise idle)

Thwarted! Was hoping to run #opencode (https://opencode.ai/) on my #RISCV system with the local llama.cpp LLM but seems its build and distribution requires the bun javascript runtime which means its platform support is quite limited <sigh>

Trying to run it under qemu and it's started up but still not settled down with qemu chewing over 200% CPU at the moment...

I'll edit this toot if it gets to a vaguely usable state

Coincidentally I was also looking for information on the SpacemiT-K3's AI capabilities and came across another of Bruno's articles. Interesting to see the performance figures here, and it's a real shame that - for now - it seems you have to ue prebuilt binaries to access the AI instructions with llama.cpp on Bianbu. But it does work. I have a local qwen2.5-coder running on mine. Just need a bit more work to let it do changes on the file system ...
