Does it suppoerts only nor based chips?

Hi Asmita, The first advice i would give is make sure you have a proper Saleae capture (e.g. your capture rate was sufficient for the speed of your device). sniffROM recognizes the commands in the commands.xlsx file and is able to parse the most commonly used ones (read, write, etc). So as long as your device uses the same commands (which briefly looking at the datasheet seems to be the case) then the tool *should* work. One caveat is that "quad I/O mode" commands are not currently supported. Do you have any error output, or what are you seeing?

Hello,
I am getting error like :

~/sniffROM$ python sniffROM.py flashSpiData.csv -o flashData.bin --summary
Parsing SPI data...

Traceback (most recent call last):
File "sniffROM.py", line 663, in
highest_byte+1, args.o, bytes_sniffed, ((bytes_sniffed / float(highest_byte)) * 100.0), bytes_sniffed_written)
ZeroDivisionError: float division by zero

Kindly let me know about this issue.

Regards
Asmita

Hello,
The above error was when I took data for 180 seconds , after taking samples for 120 seconds, I got error as :

~/sniffROM$ python sniffROM.py f1.csv -o flashData.bin --summary
Parsing SPI data...

Traceback (most recent call last):
File "sniffROM.py", line 417, in
elif ((command == 0x03) or # Read
NameError: name 'command' is not defined

Asmita, Those errors look strange.. based on the source code I don't know how they would happen. Can you confirm you have the latest code free of modifications? And were you ever able to use the tool successfully for other flash chips? Try running the tool with "-vv" for more verbosity. Would you be able to send the first 40 or so lines of the CSV input that you're using? It currently needs to match the format created by the Saleae's default SPI analyzer.

Hello,
I cloned the repository using
git clone https://github.com/alainiamburg/sniffROM.git

Currently I have tried only with this chip. Same error.
~/sniffROM$ python sniffROM.py f1.csv -o flashData.bin -vv

Where are the packet IDs? As for the data, it looks like either your miso/mosi wires are not connected properly or you caught the device in the middle of a read. I recommend you read the sniffROM wiki closely and make sure you are following the steps correctly. Make sure you understand how the SPI protocol works and get a proper logic trace capture (ideally start taking the capture first and then power on the device you are analyzing). Keep in mind the read/write commands are sent to the flash on MOSI and the flash data comes back on MISO.
