I'm looking for help in analyzing a few .bin files. I have a program that installs a "firmware" update when I connect my camera through USB.

I'm on a Mac Os Sierra. Inside the Applications Folder under this Camera App/../../ I find a folder called Resources.

Actual files can be downloaded here: .bin (if you're interested)

I did a binwalk -e to extract the data from each .bin and the did a FILE command to understand a little more of what each individual is. Here are my results below:

enter image description here

I highlighted files I thought were interesting or/and were linked or related. (Again I'm not too sure what the crap I'm doing)

I'd love to get some feedback on someone who better understands all of this. I'm trying to find the "firmware" and possibly decompile it and add a few things then put it all back together.

Thanks


John Doe,

Again thanks. Here are some images of what I was able to get working on my PC laptop using CHIPSCOPE. Chipscope came with Xilinx WebPack, like I said above in my comment. I was able to connect to my Xilinx via JTAG ports but not much past that. I'll have to research further into how to utilize the microblazer tool chains...

enter image description here

So should I bring over the .ELF files from my Mac and open them up with my SDK Tools? Or better question, where can I learn more about this process so I stop asking stupid questions? I'm not too familiar with how to use the Xilinxs SDK Tools and how to configure the FPGA with these microblazers .ELF files.

Thanks again.

Your camera has a Xilinx FPGA inside. FPGA design likely includes Microblaze soft CPU core. Files extracted by binwalk appear to be valid ELF files, so you'll just need to download Microblaze toolchain. The easiest way to do so is to download Vivado WebPack (it's free) and install it — you'll find a toolchain in the Xilinx SDK folder.

$ microblazeel-xilinx-linux-gnu-readelf.exe -S 218CC2

  • Thank you so much, it does have an FPGA Spartan 6. I've figured out the JTAG ports to it and I've connected it with Xilinx Programmer Cable. Opening it up in JTAGPort Analyser from Xilinx connects me. The only thing is all this .bin files and binwalking was done in my Mac Osx and the Xilinx JTAG port Programs I've done in my old PC Laptop. Should I copy the Extracted .bin files over to my PC? I'm sorry to ask this but how do I use the .ELF files with the Xilinx SDK Tools? – Davi Silveira Dec 21 '16 at 16:00
