+Probing
+-------
+
+The flashrom command line used was:
+
+  flashrom -p ft2232_spi:type=2232H,port=A
+
+The sigrok command line used was:
+
+  sigrok-cli -d 0:samplerate=25mhz --samples 8388608 \
+             -p '1=CS#,2=MISO,3=SCLK,4=MOSI,5=WP#,6=HOLD#' \
+             --wait-trigger --triggers 3=1 \
+             -o mx25l1605d_probe.sigrok
+
+The capturing starts when the SCLK signal is high for the first time
+(it's low per default). We capture as many samples as fit into the 8MByte
+buffer of the logic analyzer.
+
+The capture might not contain the complete flashrom chip detection sequence.
+
+
+Writing
+-------
+
+The flashrom command line used was:
+
+  flashrom -p ft2232_spi:type=2232H,port=A -w filename
+
+where 'filename' is a 2MByte file filled with lots of consecutive "HelloWorld"
+ASCII character strings.
+
+The sigrok command line used was:
+
+  sigrok-cli -d 0:samplerate=25mhz --samples 8388608 \
+             -p '1=CS#,2=MISO,3=SCLK,4=MOSI,5=WP#,6=HOLD#' \
+             -o mx25l1605d_write_hello_world.sigrok
+
 The capture is only partial, it contains a small part of the write process
 (it does not contain the chip identification, chip erase, etc. which comes
 before the actual write parts; it also does not contain anything after that,
 the flashrom command took quite a bit longer than what the capture shows).
 
+
+Reading
+-------
+
+The flashrom command line used was:
+
+  flashrom -p ft2232_spi:type=2232H,port=A -r dump.dd
+
+The sigrok command line used was:
+
+  sigrok-cli -d 0:samplerate=25mhz --samples 8388608 \
+             -p '1=CS#,2=MISO,3=SCLK,4=MOSI,5=WP#,6=HOLD#' \
+             -o mx25l1605d_read.sigrok
+
+The capture only contains a small part of the read procedure. The data in
+the chip consists of consecutive "HelloWorld" ASCII strings.
+
+
+Erasing
+-------
+
+The flashrom command line used was:
+
+  flashrom -p ft2232_spi:type=2232H,port=A -E
+
+The sigrok command line used was:
+
+  sigrok-cli -d 0:samplerate=25mhz --samples 8388608 \
+             -p '1=CS#,2=MISO,3=SCLK,4=MOSI,5=WP#,6=HOLD#' \
+             -o mx25l1605d_erase.sigrok
+
+The capture does not contain the full erase process, only a small part of it.
