The SPI interface in MACOBOX allows you to dump firmware directly from flash memory chips using either a socket or a clip — both of which are included in the MACOBOX toolkit.
Connection Options #
You can use:
- The SPI socket, for directly inserting a desoldered chip
- The SPI clip, for in-circuit dumping without desoldering
Both are compatible with the MACOBOX’s SPI slot and can be connected easily (remember to set the voltage accordingly).
Make sure to select mode S1-> OFF, S2 -> ON
Starting an SPI Dump #
Once the chip is connected via socket or clip:
- Go to the SPI page
- Press the Start SPI Dump button
- A loading spinner will appear while the dump is in progress
- When complete, the binary file will be saved under the Binaries section
What You Can Do with the Dump #
From the Binaries tab, you can:
- Press Play to extract and unpack the firmware (binwalk-style analysis)
- Press USB to export the binary file
- Associate it with a project
- Use the Share button to send the dump to the Cloud Scanner
Advanced Options #
In the Advanced section, you can:
- Rename the finding before saving it
- Manually specify the chip model, in case the auto-detection fails
Tips #
- Make sure the chip is clean and well-seated in the socket or clip
- Always check the chip orientation: most SPI chips have a small dot or notch on one corner.
This must match the dot silkscreened on the Bruschetta Box socket - It is strongly recommended to remove the voltage selector jumper before inserting the SPI socket into its slot
– This avoids accidental short circuits if the socket is misaligned
– Once the socket is properly seated and everything looks fine, you can reinsert the jumper - Some boards may require power removal or isolation to dump successfully in-circuit
