+Connect to pomona holder (8pin) like below if BeagleBone Black is used: (see links above for rasberry pi 3)

+    1 DI (IO0)    -> 18
+    2 CLK         -> 22 SPIO_SCLK
+    3 NC
+    4 VCC         -> 3 or 4 (3.3V)
+
+    8 GND         -> 1 or 2 (GND)
+    7 NC
+    6 DO  (IO1)   -> 21 SPIO_DO
+    5 CS          -> 17 SPIO_CSO

+Both chips should have the same layout. Read from both ships SPI2 (4MB) and SPI1 (8MB), save these images a number of times and make sure they seem to be correctly read from chip (i.e. verify hashsum). In my case this command was used (but usually it can detect the chip automatically):
+
+./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=1024 -r x230_spi2_3.rom -c "MX25L3206E/MX25L3208E"
