Linux는 u-boot 및 FIT(평면 이미지 트리)로 부팅할 수 없습니다.

이 질문은 정확히 동일합니다로스트보이의 문제. 글에 답변이 없어서 다시 질문드립니다.

FIT에는 서명된 커널 이미지(zImage)와 FDT가 포함됩니다. Target은 Jetson-TK1이며 기본 BSP와 매우 잘 작동합니다.

제가 무엇을 다시 확인했는지 알려주실 수 있나요?

여기에 ITS 파일과 콘솔 로그를 다음과 같이 첨부합니다.

답변1

여기서 문제는 bootargs를 설정하는 것이 없다는 것입니다. 우리가 살펴보면문서 예시먼저 다른 명령을 실행하여 bootargs를 설정한 다음 FIT를 로드하고 부팅하는 것을 볼 수 있습니다. extlinux.conf 파일의 APPEND 라인을 bootargs에 넣어야 하며 그러면 Linux가 시작되는 것을 볼 수 있습니다.
