Pico2-SPE
Overview
The Pico2-SPE is a small, low-cost, versatile boards from KWS Computersysteme Gmbh. They are equipped with an RP2350a SoC, an on-board LED, a USB connector, an SWD interface. The Pico2-SPE additionally contains an Microchip LAN8651 10Base-T1S module. The USB bootloader allows the ability to flash without any adapter, in a drag-and-drop manner. It is also possible to flash and debug the boards with their SWD interface, using an external adapter.

Programming and Debugging
The pico2_spe board supports the runners and associated west commands listed below.
As with the Pico-SPE, the SWD interface can be used to program and debug the device, e.g. using OpenOCD with the Raspberry Pi Debug Probe .
The overall explanation regarding flashing and debugging is the same as for Raspberry Pi Pico. Refer to Programming and Debugging for more information. 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 pico2_spe/rp2350a/m33 samples/basic/blinky
west flash --openocd /usr/local/bin/openocd
