Now, Rock 5 ITX+ is no x86 board, sporting an ARM Rockship RK3588 on its ITX form-factor PCB, but reading this blog post’s headline might as well give you the impression. [Venn] from the [interfacinglinux.com] blog tells us about their journey bringing up UEFI on this board, thanks to the [EDK2-RK3588] project. Why? UEFI is […]
[bogdanthegeek] has a lot of experience with the ARM platform, and their latest escapade into working with cheap ARM chips recovered from disposable vapes involved a realization that it was just plain wrong to debug such recovered silicon with something as expensive as a Pi Pico. No, they needed to build a debugger using the […]
Here’s something fun from our hacker [Piers]: Software Defined ROMs. In this series of three videos, [Piers] runs us through what a software defined ROM is, how to make them, and then how to use them. As [Piers] explains, one frustration a retro technician will face is a failed ROM chip. In the era he’s […]
Running DOOM on ARM? Old hat. Running Doom (2016) on an ARM SBC? Well, that’s a bit more interesting, and [Interfacing Linux] shows us how with this handy guide, and in a video embedded below. The ARM SBC in question is the Radxa Orion O6, which claims to be the world’s first open source ARMv9 […]
Today from the team at Cesanta Software — the people who gave us the open-source Mongoose Web Server Library and Mongoose OS — we have an article covering how to build an STM32 web dashboard. The article runs through setting up a development environment; creating the dashboard layout; implementing the dashboard, devices settings, and firmware […]
In this series of 23 YouTube videos [Rich] puts the AMD Zynq-7000 SoC through its paces by building a development board from the ground up to host it along with its peripherals. The Zynq is part FPGA and part CPU, and while it has been around for a while, we don’t see nearly as many […]
An Instruction Set Architecture (ISA) defines the software interface through which for example a central processor unit (CPU) is controlled. Unlike early computer systems which didn’t define a standard ISA as such, over time the compatibility and portability benefits of having a standard ISA became obvious. But of course the best part about standards is […]
It’s generally pretty easy to spot a microcontroller on a PCB. There are clues aplenty: the more-or-less central location, the nearby crystal oscillator, the maze of supporting passives, and perhaps even an obvious flash chip lurking about. The dead giveaway, though, is all those traces leading to the chip, betraying its primacy in the circuit. […]
Large language models (LLMs) are all the rage in the generative AI world these days, with the truly large ones like GPT, LLaMA, and others using tens or even hundreds of billions of parameters to churn out their text-based responses. These typically require glacier-melting amounts of computing hardware, but the “large” in “large language models” […]
