SD 부팅 불가

Unread post by motive1 » Thu Jan 16, 2020 4:39 pm

그동안 eMMC 부팅으로만 사용해서 확인을 못했었는데요. 구입한 XU4 2대가 모두 SD 부팅이 안됩니다.
부팅이 되지 않고 빨간LED만 들어오는 상태입니다.
PCBA : XU4Q rev 0.1 20170905

eMMC 부팅 설정시는 정상적으로 부팅이 되고 SD카드도 접근가능합니다.

ETCHER, win32diskimager 모두 해봤고, 물론 BOOT SW도 SD로 설정했습니다.

UHS-1 타입의 SD카드도 테스트 해보셨나요?

Exynos의 내부 롬 코드가 SD 카드의 특성을 타는것으로 보입니다.

UHS-I를 지원하는 다른 카드로는 SD 부팅을 성공했습니다.

Code: Select all

기존 카드도 타제조사의 Exynos7420, Exynos5420 보드에서 사용하던 것이라 카드를 바꿔볼 생각을 못했었네요.
감사합니다.
