W6300-EVB-Pico2

Overview

W6300-EVB-Pico2 is a microcontroller evaluation board based on the Raspberry Pi RP2350A and the WIZnet W6300 hardwired TCP/IP controller. It works like the Raspberry Pi Pico2, with additional Ethernet connectivity provided by the W6300. The USB bootloader allows flashing without an adapter. SWD is supported for debugging with external adapters.

Dual core Arm Cortex-M33 processor running up to 150 MHz
520 KB on-chip SRAM
2 MB on-board QSPI flash with XIP capabilities
26 GPIO pins
3 analog inputs
2 UART peripherals
2 I2C controllers
16 PWM channels
USB 1.1 controller (host/device)
3 programmable I/O (PIO) blocks
On-board LED
1 watchdog timer peripheral
WIZnet W6300 Ethernet MAC/PHY with IPv4/IPv6 support

Pin Mapping

The peripherals of the RP2350A SoC can be routed to various pins on the board. The configuration of these routes can be modified through DTS. Please refer to the datasheet to see the possible routings for each peripheral.

The W6300 is connected using SPI/QSPI signals on GPIO15-22:

GPIO	W6300 Pin	Function
GPIO15	INTn	Interrupt
GPIO16	CSn	Chip Select
GPIO17	SCLK	SPI Clock
GPIO18	IO0	MOSI / QSPI IO0
GPIO19	IO1	MISO / QSPI IO1
GPIO20	IO2	QSPI IO2
GPIO21	IO3	QSPI IO3
GPIO22	RSTn	Reset

Programming and Debugging

The w6300_evb_pico2 board supports the runners and associated west commands listed below.

	flash	debug	attach	debugserver	rtt
openocd	✅ (default)	✅ (default)	✅	✅	✅
probe-rs	✅	✅	✅	✅
uf2	✅

The overall explanation regarding flashing and debugging is the same as or Raspberry Pi Pico. See Programming and Debugging in Raspberry Pi Pico documentation. N.b. OpenOCD support requires using Raspberry Pi’s forked version of OpenOCD.

Below is an example of building and flashing the Blinky application.

# From the root of the zephyr repository
west build -b w6300_evb_pico2/rp2350a/m33 samples/basic/blinky
west flash --openocd /usr/local/bin/openocd
