## Basic Information ## Dump Flash ### Bus Pirate + flashrom ![](https://github.com/nirugima/hacktricks/blob/main/.gitbook/assets/image%20\(201\).png) Note that even if the PINOUT of the Pirate Bus indicates pins for **MOSI** and **MISO** to connect to SPI however some SPIs may indicate pins as DI and DO. **MOSI -> DI, MISO -> DO** ![](https://github.com/nirugima/hacktricks/blob/main/.gitbook/assets/image%20\(648\)%20\(1\)%20\(1\).png) In Windows or Linux you can use the program [**`flashrom`**](https://www.flashrom.org/Flashrom) to dump the content of the flash memory running something like: ```bash # In this command we are indicating: # -VV Verbose # -c The chip (if you know it better, if not, don'tindicate it and the program might be able to find it) # -p In this case how to contact th chip via the Bus Pirate # -r Image to save in the filesystem flashrom -VV -c "W25Q64.V" -p buspirate_spi:dev=COM3 -r flash_content.img ```
