There’s going to be an option called “Update Firmware.” Click on it to get to the next step. Connect your computer/laptop to your 3D printer using the USB connector that fits your machine.
- Binwalk is an open-source tool for analyzing, reverse engineering and extracting firmware images.
- We have made
- On Huawei/Honor Firmware, the Boot.img files are included within the update.app file.
- It is also possible to find, in some cases, file system images directly embedded in the firmware.
- Therefore, it always comes with the stock firmware file from the manufacturer in a compressed file.
There are two tools that you can use link from the command line to do what you’re asking. Open Esplorer, connect and wait (within a few minutes) some kind of response, that means erase process finished. It is better to cleanup the flash first before flash the firmware.
There are references to addresses of the form e000xxxx and 20000xxxx which Ghidra wasn’t able to resolve. Moreover if we search for strings we can see the strings don’t have any references pointing at them. We can note that several addresses are marked with red colored text. Ghidra marks an address in red when the specified address doesn’t exist in the file. Leaving the other options as-is we can now continue loading the file and double click to open in the disassembler. In this post we will be looking at analyzing a STM32 firmware binary in Ghidra.
Doing so makes flashing firmware definitely more complex because you cannot simply use a USB connection anymore. However, several people consider the trade-off worth it to increase their printer’s functionality.
