라즈베리파이4에 centos7 설치

라즈베리파이3까지는 centos7에서 공식적으로 이미지를 제공했지만, 라즈베리파4부터 공식 이미지이 없다. 그래서 공식이미지가 아닌 커스터마이징된 이미지를 사용해야 한다.

라즈베리 파이 와이파이 연결

3. RaspberryPi 4

이제 microSD Card를 RaspberryPi에 꽂고 전원 케이블을 연결하면 자동으로 부팅이 시작됩니다.
부팅에 성공하면 로그인을 시도합니다.

설치는 끝났으나, WI-FI가 확인되지 않고 있습니다.
WI-FI 를 인식하도록 설정 파일을 변경해야 합니다.

# Improved Bluetooth coexistence parameters from Cypress btc_mode=1 btc_params8=0x4e20 btc_params1=0x7530

적용하기 위해 CentOS를 재부팅 합니다.

# reboot

다시 로그인을 하고 WI-FI가 추가되었는지 확인합니다.

# nmcli d DEVICE TYPE STATE CONNECTION wlan0 wifi disconnected -- eth0 ethernet unavailable -- lo loopback unmanaged --

정상적으로 WI-FI가 추가되었습니다.
WI-FI를 연결하기 위해 WI-FI 목록을 조회 합니다.

WI-FI 접속에 성공하였습니다.
Windows 10 접속하기 위해 RaspberryPi에 IP를 확인해보겠습니다.
