Raspberry Pi RP2350 dev board features Ethernet RJ45 port with WIZNet W5500 or W5100S Ethernet controller

Wiznet W5500 EVB Pico2 and W5100S EVB Pico2 Dev boards

WIZnet has recently launched two new Raspberry Pi RP2350-based Ethernet boards – W5100S-EVB-Pico2 and W5500-EVB-Pico2 – based on different Ethernet controllers. The entry-level W5100S-EVB-Pico2 is built around the W5100S controller that features 4 independent sockets and 16 Kbytes of buffer memory. On the other hand, the W5500-EVB-Pico2 is built around the W5500, which features 8 sockets, 32 Kbytes of buffer memory, and improved security features such as OTP memory, Secure Boot, and Arm TrustZone technology. These make the W5500-EVB-Pico2 ideal for projects with robust network handling and advanced security measures. After the recent announcement of the $5 Raspberry Pi Pico 2 we have seen many development boards built around the RP2350 MCU, including the Challenger+ RP2350 WiFi6/BLE5, the Solder Party’s RP2350 Stamp, the Seeed Studio XIAO RP2350, the Cytron MOTION 2350 Pro, and more. Feel free to check those out If you are interested in RP2350-based dev boards. W5100S-EVB-Pico2 and […]

Cytron IRIV IO Controller – A Raspberry Pi RP2350-based industrial I/O controller

Raspberry Pi RP2350 industrial controller

Cytron IRIV IO Controller is an “Industrial Revolution 4.0” (or Industry 4.0) controller based on the Raspberry Pi RP2350 microcontroller that comes with an Ethernet port implemented through the W5500 chipset, and several isolated interfaces such as DI and DO up to 50V, two analog inputs, and RS232 and RS485 serial interfaces accessible through terminal blocks. Last year, the company introduced the Cytron IRIV PiControl industrial controller based on the Raspberry Pi CM4 module, and the IRIV IO Controller is a much cheaper solution using a subset of the features and a design that looks similar. IRIV IO Controller specifications: Microcontroller – Raspberry Pi RP2350A CPU Dual-core Arm Cortex-M33 @150MHz with Arm Trustzone for secure boot Dual-core 32-bit Hazard3 RISC-V @ 150MHz Up to two cores can be used at the same time Memory – 520 KB on-chip SRAM in 10 banks Storage – 2MB flash memory Networking – 10/100M […]

Arduino CLI 1.0 released – Let’s try it with the Raspberry Pi Pico 2

Arduino has just announced the release of the Arduino CLI version 1.0.0, the first stable release for which users and developers can be confident the software API won’t change over time, or at least with minimal changes that will not impact the workflow of applications based on it. We first looked at the Arduino CLI when it was still at the alpha stage way back in 2018. Arduino CLI version 1.0.0 was actually quietly released about two months ago, but Arduino only announced it now and the utility is now at version 1.0.4 with several bug fixes. Arduino CLI 1.0 release The goal of the API is to easily program the boards from the command line without having to use the Arduino IDE, and the CLI can be integrated into your own script to automatize various processes. Arduino explains there are three ways to integrate and utilize the capabilities of […]

How to recover a “bricked” Raspberry Pi Pico 2 or other RP2350 board

Recover Bricked Raspberry Pi Pico 2 or RP2350 board with flash_nuke.uf2

In theory, it’s close to impossible to brick your Raspberry Pi Pico 2 or other RP2350 boards because the bootrom code (source code) is stored in the 32KB ROM of the microcontroller and is by definition “read-only memory”. But I managed to “brick” my Raspberry Pi Pico 2 the other day, and even a blinky sample would not run on the board. So I’ll explain a simple method to recover/perform a factory reset of sorts. First, let me explain what happened. My board became unusable after I ran the following command while building RISC-V Linux for RP2035 and my Pico 2 was connected to the build machine:

make flash-kernel

1	make flash-kernel

At some point, it will copy a UF2 firmware binary designed for boards with PSRAM which the Raspberry Pi Pico 2 lacks:

cp build/psram-bootloader.uf2 "/media/jaufranc/RP2350"/

1	cp build/psram-bootloader.uf2 "/media/jaufranc/RP2350"/

After that, I could still see the Raspberry Pi Pico 2 board as an “RP2350” drive on my computer, […]

Using RISC-V cores on the Raspberry Pi Pico 2 board and RP2350 MCU – From blinking an LED to building Linux

Raspberry Pi Pico 2 RP2350 RISC-V review

Raspberry Pi Pico 2 was released last month with a Raspberry Pi RP2350 microcontroller equipped with two Arm Cortex-M33 cores and two 32-bit RISC-V “Hazard3” cores with up to two cores usable at any time. So in this guide, we’ll show how to use the RISC-V cores on the RP2350 MCU, compare their performance against the Arm Cortex-M33 cores, and even build Linux for RISC-V for RP2350 boards that have PSRAM. Apart from the extra memory and more powerful cores, plus new features related to security and the HSTX interface, the Raspberry Pi Pico 2 and Pico will be very similar to the end user and the instructions in our article “Getting Started with Raspberry Pi Pico using MicroPython and C” remain valid. I don’t think there’s a MicroPython RISC-V image yet, so we’ll focus on running C programs on the RISC-V cores. A quick check with the Arm cores […]

Raspberry Pi Pico Arduino core 4.0 adds support for RP2350 boards

Earle F. Philhower, III has just released the Raspberry Pi Pico Arduino core 4.0 with support for a range of Raspberry Pi RP2350 boards beside the official Raspberry Pi Pico 2. Shortly after the RP2040-based Raspberry Pi Pico board was released, we got two Arduino SDKs, the first being the community-supported Raspberry Pi Pico Arduino core maintained by Earle, and the second being the official Arduino Core Mbed 2.0 for boards as such as Arduino Nano Connect RP2040. We are again likely to have two Arduino SDKs for the RP2350 starting with the Raspberry Pi Pico Arduino core. Key changes in Raspberry Pi Pico Arduino core 4.0: Adds Raspberry Pi RP2350 support (Arm only; RISC-V cores are not supported at this stage) Migrates to Pico SDK 2.0 since it is required for RP2350 support and includes a new OpenOCD and Picotool. Tested features: SPI, I2C, LittleFS, EEPROM, PWMAudio, LWIP-based networking, […]

HDMI to screw terminal adapters could be useful for Raspberry Pi RP2040 and RP2350 boards

The very idea of an HDMI to screw terminal adapters maybe seem moronic at first, but in an era of programmable IOs (PIO), and high-speed serial transmit (HSTX), those could end up being useful for boards or modules based on Raspberry Pi RP2040 or RP2350 since they’ve all be shown to support DVI output through HDMI connectors. There are a few boards that integrate an HDMI port such as the Olimex RP2040-PICO-PC, Solder Party RP2xxx Stamp Carrier XL, or Adafruit Feather RP2040 among others, but most boards don’t include an HDMI port. What they do typically have are GPIO headers, and an HDMI to screw terminal adapter would allow users to easily add an HDMI port to their existing board without soldering simply by using jumper wires, or with a bit more work an old HDMI cable. All HDMI to screw terminal adapters are pretty basic with an HDMI male […]
