## Build and runtime testing
Tested on real Raspberry Pi Pico 2 W hardware.
- **Host:** Ubuntu 24.04
- **Toolchain:** `arm-none-eabi-gcc` 13.2.1
- **Target:** Raspberry Pi Pico 2 W (RP2350 + Infineon CYW43439), non-SMP
- **Config:** `raspberrypi-pico-2-w:telnet` (WiFi station + telnet server)
### Build
```console
$ export PICO_SDK_PATH=<path-to-pico-sdk> # supplies the CYW43439
firmware blob
$ ./tools/configure.sh raspberrypi-pico-2-w:telnet
$ make -j"$(nproc)"
[...]
$ ls -l nuttx.uf2
# nuttx.uf2 produced (~946 KB)
```
Before building, network credentials were set with `make menuconfig`
(Application Configuration -> Network Utilities -> Network initialization ->
WAPI
Configuration: SSID `<your-ssid>`, passphrase `<your-passphrase>`); the
shipped
defconfig carries only placeholders. Build completed with no errors and
produced a flashable `nuttx.uf2`.
### Flash
Written over USB in BOOTSEL mass-storage mode:
- Entered BOOTSEL (`reboot 3` from a running image, or hold BOOTSEL on
power-up).
The board enumerated as the RP2350 bootrom device (`2e8a:000f`, "RP2350"
mass-storage volume).
- Copied `nuttx.uf2` onto the mounted volume; the board accepted the image
and
rebooted automatically.
### Runtime (Wi-Fi + telnet)
After reboot the board brought up WiFi station mode, associated with the
access
point, and obtained a DHCP lease. The NSH shell was then reached over the
network via telnet:
```console
$ telnet 192.168.0.43
NuttShell (NSH) NuttX-12.13.0
nsh> uname -a
NuttX 12.13.0 <commit> <date> arm raspberrypi-pico-2-w
```
`ifconfig` confirmed `wlan0` up with the CYW43439's Broadcom MAC and a
DHCP-assigned address:
```console
nsh> ifconfig
lo Link encap:Local Loopback at RUNNING mtu 1518
inet addr:127.0.0.1 DRaddr:127.0.0.1 Mask:255.0.0.0
wlan0 Link encap:Ethernet HWaddr 88:a2:9e:xx:xx:xx at RUNNING mtu 576
inet addr:192.168.0.43 DRaddr:192.168.0.1 Mask:255.255.255.0
```
The interface stayed associated and the telnet/NSH session was responsive
(standard builtins such as `uname`, `ifconfig`, `ps`, `free` available).
> **Note on the WiFi firmware:** the CYW43439 firmware/CLM blob is **not**
> bundled with NuttX -- it is fetched from the Pico SDK at build time (via
> `PICO_SDK_PATH`, or `CONFIG_CYW43439_FIRMWARE_BIN_PATH`). If the blob is
> absent the build still succeeds using a dummy placeholder, but an image
built
> that way will boot and reach NSH yet **will not associate** to an access
> point. The runtime results above are from an image built with the real
blob.
