Microchip PIC18-Q20 low-pin count MCU comes with up to two I3C interfaces

Microchip PIC18-Q20 is a new family of microcontrollers (MCUs) with a low-pin count (14 and 20-pin packages) that integrates up to two I3C interfaces as well as multi-voltage I/O (MVIO) interfaces. MIPI I3C was first teased in 2014, then officially announced in 2017, and the first MIPI I3C specification was released the following year, as a backward compatible update to I2C with lower power consumption, and higher bitrate allowing it to compete against SPI. We’ve seen it used in a few application processors and microcontrollers, but it’s the first time I3C can be found in a lower-cost, low-pin count microcontroller. Microchip PIC18-Q20 specifications: Core – PIC18 8-bit RISC microcontroller core @ 64 MHz Memory – 1KB to 4KB RAM Storage – 16KB to 64KB with Memory Access Partition (MAP) support, 256B EEPROM Peripherals Up to 2x I3C device interfaces Adhere to MIPI I3C Basic Specification 1.0 Support Target Reset Action […]

Snagboot is an open-source cross-vendor recovery tool for embedded targets

Bootlin has just released the Snagboot open-source recovery tool for embedded platforms designed to work with multiple vendors, and currently STMicro STM32MP1, Microchip SAMA5, NXP i.MX6/7/8, Texas Instruments AM335x and AM62x, and Allwinner “sunxi” processors are supported. Silicon vendors usually provide firmware flashing tools, some closed-source binaries, that only work with their hardware. So if you work on STM32MP1 you’d use STM32CubeProgrammer, while SAM-BA is the tool for Microchip processors, NXP i.MX SoC relies on UUU, and if you’ve ever worked on Allwinner processors you’re probably family with sunxi-fel. Bootlin aims to replace all those with the Snagboot recovery tool. The Python tool is comprised of two parts: snagrecover using vendor-specific ROM code mechanisms to initialize external RAM and run the bootloader (typically U-Boot) without modifying any non-volatile memories. snagflash communicates with the bootloader over USB to flash system images to non-volatile memories, using either DFU, USB Mass Storage, or […]

Microchip unveils Single Pair Ethernet (SPE) 10BASE-T1S and 100BASE-T1 Ethernet devices

Microchip has introduced a range of industrial-grade Single Pair Ethernet (SPE) devices for IIoT and industrial Operational Technology (OT) networks for low-speed Ethernet edge devices and a simplified cabling infrastructure for latency-sensitive applications. Microchip LAN8650/LAN8651 10BASE-T1S single pair Ethernet Controllers The LAN8650 and LAN8651 10BASE-T1S MAC-PHY Ethernet controllers come with an SPI for integration into basic microcontrollers rather than higher-end MCUs with a MAC. They can be used to connect sensors, actuators, and other devices over a simple twisted-pair cable. Microchip LAN8650/LAN8651 specifications: High-performance 10BASE‑T1S single-pair Ethernet PHY Compliant with IEEE Std. 802.3cg-2019 (10BASE-T1S) 10 Mbps over a single balanced pair of conductors Half-duplex point-to-point link segments up to at least 15m Half-duplex multidrop mixing segments up to at least 25m with up to at least 8 PHYs Integrated Media Access Controller (MAC) Host interface – SPI Supports time-sensitive networking (TSN) by timestamping frame ingress and egress EtherGREEN Energy Efficiency […]

My experience installing Libero SoC in Ubuntu and Windows 10

Libero SoC Windows Silver License ACTEL_BASESOC

A few weeks ago, I received Microchip PolarFire SoC FPGA Icicle Kit with FPGA fabric and hard RISC-V cores capable of handling Linux. I wrote “Getting Started with Yocto Linux BSP” tutorial for the board, and I had initially titled the current post “Getting Started with FPGA development using Libero SoC and Polarfire FPGA SoC”. I assumed I would write one or two paragraphs about the installation process, and then show how to work with Libero SoC Design Suite to create an FPGA bitstream. But instead, I spent countless hours trying to install the development tools. So I’ll report my experience to let readers avoid some of the pitfalls, and hopefully save time. (Failing to) Install Libero SoC v2021.v2 on Ubuntu 20.04 If we go to the download page, we’ll see Libero SoC v2021.2 for Windows and Libero SoC v2021.2 for Linux. Since my computer is running Ubuntu 20.04, I decided […]

Getting Started with the Yocto Linux BSP for Polarfire SoC FPGA Icicle Kit

Getting Started Guide PolarFire SoC FPGA Icicle Kit

Last month I received Microchip PolarFire SoC FPGA Icicle development kit that features PolarFire SoC FPGA with a Penta–core 64-bit RISC-V CPU subsystem and an FPGA with 254K LE, and booted it into the pre-installed Linux operating systems based on OpenEmbedded. Today, I’ll show how to get started with the Yocto BSP and run the EEMBC CoreMark benchmark, and I’ll check out the FPGA with Libero SoC Design Suite in a couple of weeks. Operating Systems supported by PolarFire SoC FPGA My initial idea was to focus this part of the review on Linux on RISC-V status, checking some system information, running some benchmarks (e.g. SBC-Bench), compiling the Linux kernel, and installing services like a LEMP stack (Linux, Nginx (pronounced Engine-X), MySQL, PHP) which could be used for WordPress hosting for instance. But then I looked at the operating systems supported with Microchip PolarFire SoC FPGA. There’s a Yocto Linux […]

A first look at Microchip PolarFire SoC FPGA Icicle RISC-V development board

Formally launched on Crowd Supply a little over a year ago, Microchip PolarFire SoC FPGA Icicle (codenamed MPFS-ICICLE-KIT-ES) was one of the first Linux & FreeBSD capable RISC-V development boards. The system is equipped with PolarFire SoC FPGA comprised a RISC-V CPU subsystem with four 64-bit RISC-V (RV64GC) application cores, one 64-bit RISC-V real-time core (RV64IMAC), as well as FPGA fabric. Backers of the board have been able to play with it for several months ago, but Microchip is now sending the board to more people for evaluation/review, and I got one of my own to experiment with. That’s good to have a higher-end development board instead of the usual hobbyist-grade board. Today, I’ll just have a look at the kit content and main components on the board before playing with Linux and FPGA development tools in an upcoming or two posts.
