理论上一切皆有可能。在实践中，你可能会遇到困难。您是否尝试过将固件更新二进制文件扔到反汇编程序中，看看它是否是真正的指令并且没有以某种方式加密或模糊？
即使它确实是未加密的指令，您也需要了解有关文件布局的一些信息 - 没有多少芯片可以直接从复位向量开始执行 C 代码。之后，将反汇编的二进制文件重新转换为高级源代码并不是一件容易的事。当然，恢复一些你可以轻松理解和修改的东西将是一个大工程......祝你好运！
In theory anything is possible. In practice, you might have a hard time. Have you tried throwing your firmware update binary at a disassembler to see if it's real instructions and not encrypted or obscured in some way?
Even if it does happen to be unencrypted instructions, you're going to need to know something about the layout of the file - there aren't many chips out there that can start executing C code right from the reset vector. After that, turing the disassembled binary back into high-level source code is not an easy task. Certainly getting something back that you can easily understand and modify will be a big project... good luck!
