【備份】【D1 Lichee RV & WIFI】RTL8723DS & BS 的 WiFi 移植記錄

這裏是 sipeed 的大佬鼠喔，前天下午被催着處理，折騰了一天處理掉了，先上結果圖吧。

（2021-12-17 大佬鼠我發帖時，BS 加載還有一些bug，所以沒有具體的截圖）

移植方法的前提有兩個，首先拿到全志公開的 SDK ，然後在 lichee/linux-5.4/drivers/net/wireless/rtl8723ds 裏添加舊驅動升級上來。

不要去嘗試使用主線的 8723bs 驅動和其他 lichee/linux-5.4/drivers/net/ 目錄下的驅動，全志只有 XR829 上寫了sunxi相關操作，也就是說，其他地方的驅動要從這裏抄，或者從以前的舊代碼升級上來。

官方有用的訊息只有這個 https://bbs.aw-ol.com/topic/756/faq-全志d1芯片-如何移植-rtl8821cu-wifi-驅動到-linux-5-4內核/1

注意 lichee/linux-5.4/include/linux/timer.h 和 相關 lichee/linux-5.4/drivers/net/wireless/rtl8723ds/os_dep/osdep_service.c 接口的升級，vfs_read 已經發生了改變，所以要用 kernel_read 喔。

最後附帶一下我編譯好的 8723ds.ko 吧，感興趣的同學可以試試！

用法如下：

8723ds.ko

（這版模塊插入挺久的，這讓我有一點迷惑，之後我再看看要不要優化吧）

啓動一下網卡（可能）

ifconfig wlan0 up

創建 /etc/wpa_supplicant.conf 文件

ctrl_interface=/var/run/wpa_supplicant
update_config=1
network={
    ssid="Sipeed_2.4G"   
    key_mgmt=WPA-PSK
    psk="xxxxxxxxxx"                  
}

清理 ！啓動 ！

killall wpa_supplicant
wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf &
udhcpc -iwlan0 &

要注意有其他愚蠢的 wpa_supplicant 在執行導致 wlan0: WPA: 4-Way Handshake failed - pre-shared key may be incorrect 。

有問題的彩蛋：8723bs-vq0.ko （僅供測試，逃！~）

今天最多修一下 BS 的剩餘問題，之後我可能就不會再出沒了，如果你們使用上沒有問題的話。
