When switching between NodeMCU versions, see the notes about Upgrading Firmware. The unzipped file should have directory structure shown below. For the ESP32 firmware, the Espressif released firmware can be download here.

• Compression algorithms also produce results with high entropy.
• In these cases, automatic tools such as binwalk will probably not be able to obtain consistent results and a manual analysis of the file will be necessary.
• Most Android information phones run ARM, your Smart TV uses ARM, your airplane entertainment system uses ARm (or MIPS).
• You can basically repeat all the steps highlighted in the previous section, even if you’re adding Marlin for the first time to a 3D printer.
• The ELF format can be then easily disassembled, as most debuggers can read ELF files.
• This will create a directory named ‘www’ and extract the Web files there.

What you will be needing is a USB, the firmware that you need in HEX format, and, of course, Cura. The rest of the process is extremely painless to follow, so let’s get into that right away now. Like RepRap, Repetier also has a web-based configuration tool so you can make modifications to the firmware with ease and comfort. There’s also a slicer from the developer of Repetier called Repetier-Host. Marlin is popular because it has a number of desirable features that other firmware does not have. First off, it is highly customizable, meaning that you can add your own features to Marlin easily.

To correctly analyze such a file we need to specify the load address and create the memory segments. Information about the load address and memory segments can be found in the datasheet and compiler header files. The memory map can also be automatically created using SVD-Loader by parsing SVD files. SVD-Loader will only create segments that are defined in the SVD file. Thus it’s important to always cross-check with the datasheet to ensure correctness. Correspondingly on Linux we have the ELF (Executable and Linkable format) file which serves the same purpose.

The graph shows several sections of unencrypted information at the beginning and a section of encrypted or compressed information at the end. By using this command I got binary files formatted but not read by human eyes. The extracted ‘payload_dumper’ folder will contain the tool’s Python scripts as shown in the figure below.
