저는 공장에서 Android 2.2가 사전 설치된 WonderMedia 8650 CPU가 탑재된 노트북을 사용하고 있습니다. 덕분에메일링 리스트, 이것github 저장소그리고 이 관습은데비안 11설정 후 커널 5.15를 실행하는 debian 11을 부팅할 수 있었습니다. 대부분의 문제(이더넷, 키보드, 마우스패드, gpio, 화면, 직렬 콘솔)가 해결되었지만 내부 USB WiFi 어댑터와 관련된 문제를 해결할 수 있는 항목을 찾을 수 없는 것 같습니다.
내부적으로 노트북에는 USB Realtek RTL8188CTV WiFi 어댑터가 납땜되어 있으며 내부 GPIO 핀을 사용하여 켜거나 끌 수 있습니다. 해당 GPIO 핀을 성공적으로 전환할 수 있고 커널이 성공적으로 장치를 감지할 수 있지만(lsusb Bus 001 Device 005: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter:) "모르겠어요"(?) 때문에 장치를 사용할 수 없습니다. 다음 명령을 사용하여 데비안 설치 설정다중 벨트을 선택한 다음 firmware-realtek어댑터가 작동하는 데 필요한 를 설치합니다. 이제 문제가 발생합니다.
첫 번째 부팅 후 dmesg에서 장치가 제대로 작동하고 있다는 메시지를 받았지만 잠시 동안 네트워크에 연결을 시도한 후 실패하고 오류가 발생하기 시작하여 시스템이 불안정하고 응답하지 않게 됩니다. 이 상황을 복구하는 유일한 방법은 어댑터를 "분리"(GPIO 끄기)하는 것입니다. 이 상황에 대한 dmesg는 다음과 같습니다.
