The V3.2 board has the same component placement as V3.1 and works with its machine definition: RJ45 links at 2.5G, LEDs, SFP detection with DOM readings at 10G, factory MAC at 0x1FC000 and the reset button. The new target only reports "V3.2" as the machine name. Installed from the original firmware V100.9.25 through its web interface with the OEM installer image. Reading the flash in-circuit with a SOIC-8 clip gave the chip ID EF FF FF, as on a V3.1 board. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The original web interface reports this board as hardware version V3.2 (original firmware V100.9.25, January 2026).
Compared to V3.1
The component placement matches 2M-PCB23-V3.1: same
positions for the flash (U8), the T7/T8/T9/T10 headers, the SFP cage and its
LED, and the unpopulated U7/U9 footprints. Build with
MACHINE=KP_9000_9XHML_X_V3_2, which uses the V3.1 machine definition and
only differs in the reported name.
Tested
Installed from the original firmware through its web interface with
installer/output/rtlplayground_oem_upgrade.bin, then:
- RJ45 ports link at 2.5G; LEDs: orange at 2.5G, green below
- SFP port: module detected with vendor/model/serial and DOM readings (temperature, Vcc, TX bias, TX/RX power), link up at 10G
- factory MAC read from flash (0x1FC000)
- reset button (GPIO48): held for more than 10 s it restores the default config
Flash access
Reading the flash in-circuit with a SOIC-8 clip did not work: the chip ID
comes back as EF FF FF (only the manufacturer byte is right) and reads
return 0xff, the same as on a V3.1 board. The switch chip is powered through
the clip and keeps driving the SPI lines. Make sure a way back is acceptable
before installing, or hold the switch chip in reset while reading.
