## Summary New RISC-V chip port for the GigaDevice **GD32VW55x** (Nuclei N307, Wi-Fi 6 + BLE 5.3) and the GD32VW553K-START board. The radio comes from the prebuilt vendor libraries behind a thin sys_* facade; the SDK is cloned and pinned at build time (same pattern as esp-hal-3rdparty). Everything that touches hardware registers is a native NuttX driver. HAL drivers: serial, DMA, GPIO/EXTI, SPI, I2C, ADC, PWM, input capture, FWDGT and WWDGT watchdogs, PROGMEM (internal flash via the mask ROM API), TRNG, CRC, RTC, plus board LEDs and software reset. Wi-Fi (wlan0, station and softAP) is a netdev_lowerhalf driver on the NuttX network stack. BLE 5.3 is present but EXPERIMENTAL and off by default. Full details are in the new documentation under Documentation/platforms/risc-v/gd32vw55x/. <img width="652" height="771" alt="gd32vw553k-start" src="https://github.com/user-attachments/assets/db136683-f4ac-4270-a267-f92f383112df"; /> ## Impact New arch/chip and board; no existing code is changed. The Wi-Fi/BLE configurations need the vendor SDK (fetched at build time); nsh and periph build without it. ## Testing Built on Linux with riscv-none-elf-gcc 14.2.0; all five configurations build, nxstyle is clean, docs build without warnings. Validated on hardware (**GD32VW553K-START**: - nsh / periph / littlefs — boots, drivers register, TRNG and LEDs work, LittleFS survives a reboot. - Wi-Fi station: scan, WPA2 four-way handshake, DHCP, ping gateway and 8.8.8.8 (3/3). - Wi-Fi softAP: nuttxwifi up (WPA2, ch 11), visible from a laptop. - BLE: advertises as NuttX; a central connects and enumerates GATT. -- This is an automated message from the Apache Git Service.
