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 […]

MILK-V Jupiter review – A RISC-V mini-ITX motherboard and PC tested with Ubuntu-based Bianbu OS

Milk-V Jupiter RISC-V computer review

In this review or preview of the the Shenzhen Milk-V Jupiter RISC-V mini-ITX motherboard, I’ll assemble the motherboard into a mini-ITX chassis, before installing the Ubuntu 23.10 Mantic-based Bianbu OS optimized for RISC-V platforms, and testing the device to see how much progress has been done on RISC-V since I tested the StarFive VisionFive 2 SBC with Debian 12 about 18 months ago. In the first part of the review, we checked out the Radxa ROCK 5 ITX (Rockchip RK3588 Arm) and Jupiter (SpacemIT K1 RISC-V) mini-ITX motherboards with specifications and unboxing, and the Auriga 6-Bay NAS mini-ITX chassis used in this review. I planned to start with the Radxa ROCK 5 ITX, but due to logistics and technical issues, I went ahead testing the RISC-V motherboard first. Installing Bianbu OS to the Jupiter RISC-V motherboard The board does not come with storage, so no operating system is installed. So […]

$5 Raspberry Pi Pico 2 launched with Raspberry Pi RP2350 dual-core RISC-V or Arm Cortex-M33 microcontroller

Raspberry Pi Pico 2

The Raspberry Pi Pico 2 is an MCU development board based on the new Raspberry Pi RP2350 dual-core RISC-V or dual-core Cortex-M33 microcontroller with 520 KB on-chip SRAM, a 4MB flash, a micro USB port for power and programming and the same GPIO headers as the Raspberry Pi Pico board with an RP2040 dual-core Cortex-M0+ microcontroller with 264KB SRAM. The RP2350 embeds both an open-source Hazard3 RISC-V dual-core CPU and a dual-core Cortex-M33, but only one cluster can be used at a given time. Apart from the faster MCU cores and higher SRAM capacity, the RP2350 is about the same as the RP2040, albeit it also adds one extra PIO block bringing the total to three. One important new feature is built-in security when using Arm Cortex-M33 cores with Trustzone and other security features. Raspberry Pi RP2350 microcontroller Let’s have a closer look at the RP2350 microcontroller, before checking out […]
