Renesas RZ/A3UL Cortex-A55 CPU runs RTOS for HMI with quick startup times

Renesas RZ/A3UL is a single-core Cortex-A55 processor clocked at up to 1 GHz designed to run FreeRTOS or Azure RTOS on high-definition (1280×800) HMI solutions requiring quick startup times such as industrial equipment, home appliances, office automation equipment, audio equipment, and POS terminals. The new RZ/A3UL processor family has the same peripheral functions and package pin assignments as the RZ/G2UL (Arm Cortex-A55/M33) and RZ/Five (RISC-V) families targeting Linux-based HMI applications. Renesas also designed a SMARC 2.1 compliant System-on-Module (SoM) based on the Renesas RZ/A3UL microprocessor to speed up time to market. Renesas RS/A3UL specifications: CPU – Single-core Arm Cortex-A55 processor @ up to 1.0 GHz with 32KB I-cache with parity, 32KB D-cache with ECC, 256KB L3 cache with ECC Internal Memory – 128KB SRAM with ECC Memory & Storage I/F 16-bit DDR4-1600 or DDR3L-1333 memory interfaces with in-line ECC; up to 4GB RAM Octal Peripheral Interface (OPI) for flash or […]

52Pi CM4 Router Board also features HDMI, 40-pin Raspberry Pi HAT header, and OLED display

We’ve already seen compact Raspberry Pi CM4 based router boards with two Ethernet ports from DFRobots, Seeed Studio, and MCUZone. 52Pi CM4 Router Board expands on the same principle but also offers HDMI output, a 40-pin GPIO header for Raspberry Pi HAT expansion boards, and a small OLED information display. The board also includes two Gigabit Ethernet, plus the WiFi and Bluetooth connectivity from the Raspberry Pi CM4, and the extra features make the board larger (146x50mm) than competitors. But that makes the platform that much more flexibly, and can be used as a gateways for all sorts of projects thanks to the wide range of Raspberry Pi HAT available in the market. 52Pi CM4 Router Board (EP-0146) specifications: Compatible with Raspberry Pi Compute Module 4 series Storage – MicroSD card slot (only used with Raspberry Pi CM4 Lite) Video Output – HDMI 2.0 port up to 4Kp60 Display – […]

HydraUSB3 RISC-V MCU board combines USB 3.0 with HSPI and SerDes high-speed interfaces

Benjamin VERNOUX has launched the HydraUSB3 V1 board based on WCH CH569 RISC-V MCU as a developer platform to experiment with high-speed protocols like HSPI and SerDes through a USB 3.0 interface. It’s the third board from Benjamin we feature here, after the STM32-based HydraBUS and the HydraNFC v2 shield delivering up to 1600 mW for NFC charging and connectivity. The HydraUSB3 v1 is quite different since it does not involve NFC at all, and instead leverages the CH569’s high-speed interfaces including USB 3.0 (5 Gbps), HSPI (3.8Gbps), and SerDes (>1.2Gbps). HydraUSB3 V1 specifications: MCU – WCH CH569 32-bit RISC-V (RISC-V3A) RV32IMAC MCU @ 120MHz with 16KB 32-bit SRAM, 96KB configurable 128-bit SRAM, 448KB code flash, 32KB data flash USB – 1x USB 3.0 host/device port that supports the USB 3.0 SS built-in PHY (5Gbps) and USB 2.0 built-in PHY FS/LS/HS (480Mbps) High-speed I/Os High-Speed Parallel Interface (HSPI) up to […]

Inexpensive, Snapdragon 410-based “4G LTE WiFi Modem” made to run Debian 11

Some ultra-compact 4G LTE wireless routers housed in what looks like a largish USB dongle are based on Qualcomm Snapdragon 401 (MSM8916) quad-core Cortex-A53 processor and have been hacked to run Debian 11 with Linux 5.15 instead of the pre-loaded Android OS. Soon after Extrowerk had purchased a ~$20 “4G LTE WiFi modem” USB dongle, he noticed it would show as “Android” when connected to his PC. It also turned out that Chinese hacker HandsomeYingYan had already done some work on the device modding the lk2nd bootloader and the Linux kernel for the OpenStick project for “mainline Linux on msm8916-based 4G USB modem”, and documented his work (in Chinese) to run Debian 11 on the “4G USB WiFi Modem” pictured below. Let’s go through some of the specifications of the said wireless router: SoC – Qualcomm Snapdragon 410 (MSM8916) quad-core Arm Corte-A53 processor with System Memory – 512 MB RAM […]
