Raspberry Pi Pico W

Boots real Raspberry Pi Pico W (RP2040 + Infineon CYW43439 WiFi) firmware on rp2040js. The default firmware is the official Pico W MicroPython build: it brings up a live REPL on the USB-CDC serial console — click the panel and type real Python (try print(2+2) then Enter). The defining Pico W quirk is that the on-board LED is not an RP2040 GPIO — it hangs off the CYW43439 WiFi chip and is driven over the chip's gSPI bus. The "CYW43 LED" firmware in the picker is a bare-metal program that drives the on-board LED through the CYW43439 with the real chip-GPIO ioctl (the gpioout iovar for WL_GPIO0), so the panel LED toggles via the WiFi chip exactly as the quirk describes. A third firmware, Hello UART, prints a banner on UART0. Open the debugger to single-step the ARM Cortex-M0+, read/write r0-r15/xPSR, disassemble the XIP flash and boot ROM, set breakpoints and write-watchpoints over the real RP2040 memory map. On-board only — the CYW43 LED and serial — with no external components, and the bare Pico W is naturally silent.
