C++中的固件更新如何实现？

#include <iostream>
#include <fstream>
#include <vector>

class FirmwareUpdater {
private:
    std::vector<uint8_t> firmwareData;
    std::string firmwareFilePath;

public:
    FirmwareUpdater(const std::string& filePath) : firmwareFilePath(filePath) {}

    bool loadFirmware() {
        std::ifstream file(firmwareFilePath, std::ios::binary);
        if (!file) {
            std::cerr << "无法打开固件文件: " << firmwareFilePath << std::endl;
            return false;
        }

        file.seekg(0, std::ios::end);
        size_t fileSize = file.tellg();
        file.seekg(0, std::ios::beg);

        firmwareData.resize(fileSize);
        file.read(reinterpret_cast<char*>(firmwareData.data()), fileSize);

        if (file.fail()) {
            std::cerr << "读取固件文件失败" << std::endl;
            return false;
        }

        return true;
    }

    bool updateFirmware() {
        if (firmwareData.empty()) {
            std::cerr << "固件数据为空" << std::endl;
            return false;
        }

        // 这里应该有实际的固件写入逻辑
        // 例如：写入到闪存或其他存储介质
        std::cout << "正在更新固件..." << std::endl;
        // 模拟写入操作
        for (size_t i = 0; i < firmwareData.size(); ++i) {
            // 实际写入操作
        }

        std::cout << "固件更新完成" << std::endl;
        return true;
    }
};

int main() {
    FirmwareUpdater updater("firmware.bin");
    if (updater.loadFirmware()) {
        if (updater.updateFirmware()) {
            std::cout << "固件更新成功" << std::endl;
        } else {
            std::cout << "固件更新失败" << std::endl;
        }
    } else {
        std::cout << "加载固件失败" << std::endl;
    }

    return 0;
}
