+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](2M-PCB23-V3_1.md): 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.
