Pico2-Ice development board combines Raspberry Pi RP2350B with Lattice iCE40UP5K FPGA

pico2 ice Raspberry Pi RP2350B + iCE40UP5K FPGA development baord

tinyVision.ai has recently released the second-generation ot its open-source hardware pico-ice FPGA development board, upgrading the Raspberry Pi RP2040 to the newer RP2350B along with dedicated user LEDs and buttons for both the MCU and the FPGA. The Pico2-Ice also exposes the RP2350B’s HSTX interface through a 22-pin connector, while keeping the same Lattice iCE40UP5K FPGA. The onboard iCE40UP5K FPGA features 5.3k LUTs, 1 MB SPRAM, and 120 KB DPRAM, along with 4MB SPI flash and 8MB low-power PSRAM. The board also exposes all RP2350 pins and 32 FPGA GPIOs via 2.54mm pitch headers in Pmod format. It includes two RGB LEDs and two pushbuttons (separately mapped to the MCU and the FPGA), and integrates onboard 3.3V/1.2V regulators for power. These features make this board suitable for exploring HDLs, embedded systems, and FPGA programming with open-source tools.

Raspberry Pi RP2350 A4 stepping fixes E9 GPIO Erratum, glitching bugs, introduces 2MB flash variants

The Raspberry Pi RP2350 dual-core Arm/RISC-V has gotten a new version – A4 stepping – addressing bugs and security vulnerabilities, notably the infamous E9 GPIO erratum and glitching bugs in the A2 stepping identified by the 2024 Hacking Challenge. Both RP2350A and RP2350B variants will benefit from the new stepping and be marked RP2350A0A4 and RP2350B0A4, respectively. The company also announced the availability of the 2MB flash variants, the RP2354A and RP2354B (unveiled in March 2025), that do not require flash on the board. RP2350 A4 stepping highlights: Fixes Glitching bugs identified in the 2024 Hacking Challenge. Exploits required physical access to the chip. The E9 GPIO erratum related to GPIO pull-ups. A4 stepping is a drop-in replacement for the earlier A2 stepping. 5V-tolerant GPIOs; Note: the chip must remain powered while 5V IOs are used (See updated datasheet for details) RP2354A and RP2354B variants with 2MB of stacked-in-package QSPI […]
