1 This is an example capture of a Macronix MX25L1605D (MX25L1605DPI-12G)
2 SPI flash chip (16MBit == 2Mbyte; NOR flash) that is being written to.
4 The SPI programmer hardware used is openbiosprog-spi, see
6 http://randomprojects.org/wiki/Openbiosprog-spi
8 The software used for programming it is flashrom, see
10 http://flashrom.org/FT2232SPI_Programmer
12 The command line used was
14 flashrom -p ft2232_spi:type=2232H,port=A -w filename
16 where 'filename' is a 2MByte file filled with lots of consecutive "HelloWorld"
17 ASCII character strings.
19 The logic analyzer used for capturing is a ChronoVu LA8 at a sample rate
20 of 25MHz. The capture was done using sigrok (11/2011) via
22 sigrok-cli -d 0:samplerate=25mhz --samples 8388608 \
23 -p '1=CS#,2=MISO,3=SCLK,4=MOSI,5=WP#,6=HOLD#' \
24 -o mx25l1605d_write_hello_world.sigrok
26 The ChronoVu LA8 probes were connected like this to the MX25L1605D chip:
29 ------------------------
31 1 (orange) SO/SIO1 (a.k.a MISO)
33 3 (red) SI/SIO0 (a.k.a MOSI)
38 The capture is only partial, it contains a small part of the write process
39 (it does not contain the chip identification, chip erase, etc. which comes
40 before the actual write parts; it also does not contain anything after that,
41 the flashrom command took quite a bit longer than what the capture shows).
