Cologne Chip releases an open-source integrated logic analyser (ILA) for GateMate FPGA chips

Integrated logic analyser ILA Cologne GateMate FPGA

Cologne Chip’s “Integrated logic analyzer” (ILA) project is an open-source Verilog implementation of a logic analyzer running on the company’s GameMate A1 FPGA and designed to capture internal signals. When we first covered the GameMate A1 FPGA we noted Cologne relies on the open-source Yosys framework coupled with a proprietary, but free-of-charge, place & route tool contrary to most other FPGA vendors that only offer closed-source proprietary development tools. The German company has now released the GateMate integrated logic analyzer project to help customers debug their FPGA designs. The project includes the digital circuit of the ILA designed in the hardware description language Verilog and a Python program (ILA Control Program) used to configure the configuration of the ILA from the design under test (DUT) and provide an interface with the user during the debugging process. The user will also need a GateMate FPGA toolchain and GTKWave open-source program to […]

Zigbee Home is an ESPHome-like firmware project for Zigbee devices

Zigbee Home firmware project aims to provide similar functionality to ESPHome open-source firmware, but for Zigbee devices based on Nordic Semi nRF52 wireless microcontrollers, and later on the newer nRF53 MCUs.

The firmware relies on Nordic Semi ZBOSS for Zigbee 3.0 stack and should eventually enable a range of Zigbee devices to be flashed with open-source firmware and facilitate integration with Home Assistant open-source home automation framework through ZHA integration, and support for Zigbee2MQTT is also being worked on.

ArduinoSimulator is an open-source Arduino Simulator that runs in your web browser

Leonardo Russo’s ArduinoSimulator is an open-source Arduino Simulator written in JavaScript that runs code directly in your web browser and shows the serial output and digital/analog pins status for various Arduino boards namely Arduino UNO R3, MEGA1280, MEGA2560, and NANO V3. We previously covered the Wokwi simulator for ESP32. Arduino, and Raspberry Pi RP2040 that’s a great little tool for educators to emulate circuits and run code right in a web browser, and it even supports the ESP32-P4 wireless MCU although it’s yet to be released. While the simulators are written in JavaScript and open-source, the tool itself is not, and for instance, you can’t run a self-hosted instance of Wokwi or use it offline. The ArduinoSimulator is fully open-source and runs entirely from a web browser. It’s not quite as complex and full-featured as Wokwi, as you can’t build your own circuits, but you still have an area to […]

Debian 12 and Linux upstreaming for the Qualcomm Snapdragon X Elite SoC

When Qualcomm launched the powerful 4.2 GHz Snapdragon X Elite 12-core Arm SoC for “mobile PCs” (better known as laptops), I was surprised they showed benchmarks for both Windows and Linux as in the past, the company focused on Windows only for this type of processor. But at the time we were only shown Geekbench 6.2 results in Linux, so it was not clear what was supported at the time. But a recent post by Abel Vesa, Linaro engineer, explains a fully working Debian 12 image with GPU rendering and WiFi connectivity was ready right before launch and work is now being done to upstream the code to Linux mainline. In this post, he shares the Linux upstreaming plan and provides instructions to install Debian 12 on an official Snapdragon X Elite reference design. Upstreaming will be done in two parts, starting with support for the following: Qualcomm Oryon CPUs Clocks, […]

OpenWrt One/AP-24.XY is an upcoming router board developed by OpenWrt and Banana Pi

OpenWrt developers have started the process to develop the “OpenWrt One/AP-24.XY” router board based on MediaTek MT7981B (Filogic 820) SoC and MediaTek MT7976C dual-band WiFi 6 chipset, and designed in collaboration with Banana Pi that will also handle manufacturing and distribution of the router board. As of the OpenWrt 23.05 release, close to 1,800 routers and other devices are officially supported by the lightweight embedded Linux operating system, and many more claim to be running OpenWrt through a fork of the OS. But none of those are made by OpenWrt developers who have now decided to create their own router board in collaboration with Banana Pi since they’ve done such boards including the BPI-R4 WiFi 7 router SBC. OpenWrt One/AP-24.XY preliminary specifications: SoC – MediaTek MT7981B (Filogic 820) dual-core Cortex-A53 processor @ 1.3 GHz System Memory – 1GB DDR4 Storage 128 MB SPI NAND flash for U-boot and Linux 4 […]

Tillitis Tkey is an open-source RISC-V security key in a USB-C case

Tillitis’ TKey is a small, simple security key in a USB-C form factor, and described as a “new type of flexible USB security token” that is inspired by DICE (Device Identifier Composition Engine) and measured boot powered by a simple 32-bit RISC-V core, the PicoRV32, in a Lattice iCE40 UP5K FPGA. While we have covered hardware security modules in the past, this is the first security key we have seen that is based on an FPGA running a RISC-V core. The security token lacks persistent, onboard storage, unlike alternatives such as Yubikey Neo. Apps need to be loaded onto the key every time it is connected to a host device. It uses measured boot to generate a unique identifier for each application and is more secure than the alternatives since private keys are not stored on the device. Also, the hardware and software for the TKey are completely open-source for […]
