Nanopi R4S(Rockchip RK3399 ARM64 SoC)에 OpenBSD 7.2를 설치하려고 할 때 다음과 같은 SD 카드 문제가 발생했습니다. 같은 질문이전에 OpenBSD 7.1에서 설명했습니다..
sdmmc0: can't enable card
설치 프로세스가 평소와 같이 시작되지만 계속해서 디스크를 선택하면 사용 가능한 디스크가 없습니다.
Available disks are: .

Welcome to the OpenBSD/arm64 7.2 installation program.
다음 문구도 내 관심을 끌었습니다.
Loading Environment from MMC... MMC Device 0 not found
*** Warning - No MMC card found, using default environment
누구든지 이 문제를 해결하도록 도와줄 수 있나요? 나는 U-boot에 대해 잘 모르지만 이것이 OpenBSD 문제인 것 같습니다.
미리 감사드립니다!
