重现步骤
我尝试使用 CanMV-K230_debian_sdcard_sdk_1.3.img.gz 在 CanMV K230 启动 debian，但我使用 ifconfig 查看网络接口时发现没有无线网络驱动。但使用 CanMV-K230_sdcard_v1.7_nncase_v2.9.0.img.gz 启动的 buildroot 系统存在 wlan0 和 wlan1 两个接口。我想将 buildroot 中的 wifi 模块移植到 debian 上。
期待结果和实际结果
我现在希望在 debian 中安装好 wifi 驱动，并且我也知道对应的模块名称为 bcmdhd。但实际上在 dmesg 中和 ifconfig 中都没有 wifi 相关的信息。
软硬件版本信息
开发板名称：CanMV K230
WiFi模块：AP6212 L318400912414
内核：Linux 5.10.4
发行版：Debian trixie/sid
尝试解决过程
因为 buildroot 和 debian 的 Linux 内核版本相同，我尝试将 CanMV-K230_sdcard_v1.7_nncase_v2.9.0.img.gz 中的 /lib/modules/5.10.4 拷贝到 debian 的对应路径，然后重启的 dmesg 输出见错误日志：
我也找到了 bcmdhd 对应的模块源码 https://github.com/StreamUnlimited/broadcom-bcmdhd-4359 以及固件 https://github.com/HiFDW/broadcom-ap6212/
请问接下来我应该怎么做？
