flashreader 1.0.0

Read/write i2c & spi memory chipsets (Flash & EEPROM)

Python Flash Reader

Flash Reader allows to read and/or write any EEPROM or Flash memory via SPI or I2C. This library is particularly useful in case of reverse engineering or prototyping for embedded systems (RPI, etc..).

Supported platform

• Raspberry pi 4
• FT232H (Adafruit)

Support memory

• Various spi serial flash
• Macronix mx25R..., mx25L...
• Microchip 25aa..., 25lc...
• Winbond w25q...
• Microchip 24lc...

Quick start (Raspberry pi 4)

Setup Raspbian

apt-get install python3 python3-pip python3-spidev python3-monotonic
sudo raspi-config

• Go to "Interfacing Options" > "SPI" > "Enable"
• Reboot the RPI

Wiring

• SPI: PIN19(MOSI), PIN21(MISO), PIN23(SCK), PIN11(CS)
• I2C: PIN3(SDA), PIN5(SCL)

Quick start (Windows)

Setup Windows

• Plug FT232H
• Use Zadig (https://zadig.akeo.ie/), select the USB device in the list, select libusb-win32 and replace the driver (DO NOT USE WINUSB or any other driver).

Wiring

• SPI: D0(SCK), D1(MOSI), D2(MISO), D3(CS)
• I2C: D0(SCL), D1(SDA)

Run

Read spi flash (By using generic driver: spiflash)

python -m flashreader --platform raspberrypi --memory spiflash --read ./dump.bin --offset 0

Write spi flash (By using generic driver: spiflash)

python -m flashreader --platform raspberrypi --memory spiflash --write ./dump.bin --offset 0
