Reset wait busy status = 0xffffffff time out Use Default - Total size = 8MB, Sector size = 64KB SF1: ManufID = FF, DeviceID = FFFF (Missing or Unknown FLASH) The first steps involve switching it to UART mode and setting serial parameters (baud rate, parity bits, stop bits, polarity):ĭevice clock is disabledethaddr.found Once our target is connected to the Bus Pirate, it’s time to configure it to act as a UART transparent bridge. The diagram below will give you some information about the required connections. I’ll be using a bus pirate in UART transparent bridge mode here. I won’t cover the details on how to identify GND, Vcc, Rx, and Tx pins here, but I recommend you read Hardware 101 recent post if you want to learn how to do that with a simple multimeter. The four pins slot highlighted in red is a good candidate for UART serial port. If we remove the two enclosure screws and open it up, we immediately identify two pinout slots: If you missed the introductory post you can find it here Man-in-the-conference room - Part I (Introduction). In this post I’ll describe how I used hardware hacking techniques to get more information about the device and dump its internal storage.
