Intel kills PathFinder IDE for RISC-V processors

Intel PathFinder Discontinued

Intel has just discontinued PathFinder Eclipse-based development environment for RISC-V processors with the website now reading: We regret to inform you that Intel is discontinuing the Intel Pathfinder for RISC-V program effective immediately. Since Intel will not be providing any additional releases or bug fixes, we encourage you to promptly transition to third-party RISC-V software tools that best meet your development needs. PathFinder was a pre-silicon open-source development environment with support for vairous RISC-V cores, a set of other IP’s, multiple operating systems, and toolchains. It allowed designers to create RISC-V SoCs to and run them on FPGA platforms such as the Terasic developer kit or Startix-10 GX evaluation kit. PathFinder appears to just be one of the casualties after Intel reported a loss for Q4 2022, and announced it will lose even more in Q1 2023 with Tom’s Hardware also highlighting Intel would stop investing in new products for […]

HiFive Pro P550 “Horse Creek” RISC-V motherboard with 16GB RAM to launch this summer

SiFive HiFive Pro P550 RISC-V motherboard based on Intel “Horse Creek” quad-core SiFive Performance P550 processor will launch this summer with 16GB DDR5 memory, two PCIe expansion slots, Gigabit Ethernet networking, USB 3.x ports, and on-board graphics. Intel Horse Creek platform was first revealed when SiFive unveiled the SiFive Performance P550 64-bit RISC-core with Cortex-A75 class performance in June 2021. The companies then demonstrated an internal Intel Horse Creek board with 8GB DDR5 and PCIe Gen5 at the Intel Innovation 2022 Developer Conference last October, and it looks like the 7nm RISC-V processor, manufactured with an Intel 4 process, will finally be available to developers this summer with the launch of the HiFive Pro P550 motherboard/development system.   HiFive Pro P550 preliminary specifications: SoC – Intel-SiFive Horse Creek SoC equipped with 4x SiFive Performance P550 RV64GBC RISC-V cores with a 13-stage, 3-issue, out-of-order (OoO) pipeline GPU – “On-board graphics” [Update: […]

HPMicro HPM64G0 – A 1 GHz RISC-V microcontroller

Yesterday, I ended up on the HPMicro website showing the illustration above about a 1 GHz MCU called HPM64G0. It looked interesting enough so I clicked on the link to a page with some documentation for the company’s HPM6700/6400 microcontrollers. But in typical Chinese fashion, I was asked for a mobile phone number to download the documents. No luck this time since a Chinese mobile phone number is required. If anybody can set up a mirror on Mega or other websites easily accessible outside of China that would be appreciated. But eventually, I found an article in Chinese on EETrend where we can learn more about the HPM64G0 which happens to be a 1GHz microcontroller based on the RISC-V architecture. We already had one of those for Arm with the NXP i.MX RT1170, but I had yet to see any RISC-V microcontrollers clocked at such a high frequency. HPMicro HPM64G0 […]

LILYGO T-RSC3 ESP32-C3 board features isolated RS232 & RS485 interfaces, 5 to 24V DC input

LILYGO T-RSC3 is a relatively compact ESP32-C3 board with WiFi 4 and Bluetooth LE 5.0 connectivity, support for RS232 and RS485 communication protocols through a DB9 connector and a terminal connector respectively, and a wide 5V to 24V DC power input. LILYGO had already made an ESP32 board with CAN Bus and RS485 interfaces called the T-CAN485, but without any isolation. The new T-RSC3 offers both RS232 and RS485 interfaces, but no CAN Bus, protected by isolated transceiver modules that should make it safer to use in industrial environments. LILYGO T-RSC3 board specifications: Wireless module – Espressif Systems ESP32-C3-MINI-1U module with ESP32-C3 RISC-V microcontroller @ 160 MHz with 400 KB SRAM, 2.4 GHz WiFi 4, Bluetooth 5.0 LE & Mesh, 4MB flash, and a u.FL antenna connector Industrial control interfaces RS232 via DB9 connector, RSM232MT5V isolated transceiver with 3000V isolation, 4.75~5.25V input, 5V/50mA output, baud rate from 1200 to 256,000 […]

Espressif ESP32-P4 – A 400 MHz general-purpose dual-core RISC-V microcontroller

Espressif ESP32-P4 is a general-purpose dual-core RISC-V microcontroller clocked at up to 400 MHz with AI instructions extension, numerous I/Os, and security features. It also happens to be the first microcontroller from Espressif Systems without wireless connectivity, and as such, it should probably be seen as an alternative to STM32F7/H7 or NXP i.RT Arm Cortex-M7 microcontrollers/crossover processors, and likely offered at a significantly lower cost. It should also offer lower power consumption than other ESP32 chips thanks in part to a third RISC-V core clocked at 40 MHz that can keep the system running while the other two high-performance cores are down. ESP32-P4 key features and specifications: MCU subsystems Dual-core RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU, 768KB of on-chip SRAM Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz with 8KB of zero-wait TCM RAM Memory & Storage I/F […]

Year 2022 in review – Top 10 posts and statistics

It’s the last day of the year and the time to look at some of the highlights of 2022, some traffic statistics from CNX Software website, and speculate on what 2023 may bring us. The semiconductors shortage continued in 2022, but things are looking brighter in 2023 with the full reopening of the world mixed with forecasts of difficult economic times that should keep the demand/supply equation in check. On the Arm processor front the biggest news of the year, at least in this corner of the Internet, was the launch of the Rockchip RK3588 octa-core Cortex-A76/A55 processor together with interesting single board computers that we’ll discuss below. Announced last year, the Amlogic A311D2 octa-core Cortex-A73/A53 was finally made available in a few SBC’s, and we finally got some news about the Amlogic S928X Cortex-A76/A55 SoC showcased in 8K TV boxes, but we have yet to see it in action.

Lichee Pi 4A RISC-V SBC takes on Raspberry Pi 4 with TH1520 processor

Lichee Pi 4A is a single board computer (SBC) powered by Alibaba T-Head TH1520 quad-core RISC-V Xuantie C910  processor @ 1.8 GHz with an Imagination GPU and a 4 TOPS NPU for AI that can compete against the Raspberry Pi 4 in terms of performance and features. We previously mentioned the Lichee Pi 4A (LPi4A) in our article about the Sipeed LM4A RISC-V system-on-module, but at the time we only had some benchmarks for the board and no photos and specifications about the SBC. Sipeed has now released photos and more detailed specifications and is taking “pre-orders”. So let’s have a look. Lichee Pi 4A specifications against the ones for Raspberry Pi 4.   The TH1520 used to be advertised at up to 2.5 GHz, but it seems to have now come down to 1.8 GHz. Software support will include Debian, OpenWrt, and Android in Q1 2023, and more operating […]

Pinecil V2 Bluetooth LE soldering iron gets a web interface

It’s now possible to make use of the Pinecil V2 soldering iron‘s Bluetooth LE connectivity through a web-based interface used to monitor and/or set the temperature and power of the RISC-V soldering iron. When the Pinecil V2 soldering iron was launched with a Bouffalo Lab BL706 RISC-V Bluetooth microcontroller last summer, we were told there were main potential cases to make use of the Bluetooth LE features: OTA firmware upgrade and remote telemetry and control. The latter is now being taken care of by Joric who has written a  web application to visualize telemetry data and even control the temperature of the soldering iron. To be able to use the Bluetooth features, you’ll first need to install the latest Pinecil V2 firmware with blisp flashing utility before going to https://joric.github.io/pinecil to pair your soldering iron as explained in the wiki. Note the implementation relies on the Web Bluetooth API which […]
