Firmware image found with MediaTek MT76xx wifi chipsets.
This page hosts a formal specification of Andes Firmware Image layout as seen in MT76 Wifi Chipsets using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.
All parsing code for C# generated by Kaitai Struct depends on the C# runtime library. You have to install it before you can parse data.
The C# runtime library is available in the NuGet Gallery. Installation instructions can also be found there.
Parse a local file and get structure in memory:
var data = AndesFirmware.FromFile("path/to/local/file.bin");
Or parse structure from a byte array:
byte[] someArray = new byte[] { ... };
var data = new AndesFirmware(new KaitaiStream(someArray));
After that, one can get various attributes from the structure by accessing properties like:
data.ImageHeader // => get image header
// This is a generated file! Please edit source .ksy file and use kaitai-struct-compiler to rebuild
namespace Kaitai
