내 램디스크가 Linux 이미지의 일부이기 때문에 U-Boot가 부팅 시 uramdisk를 사용하지 않도록 지정하고 싶습니다. 문제는 수정된 sdboot를 선택하고 "bootm {linux} - {devicetree}"를 호출해도 uramdisk.image.gz 파일이 있는지 확인한다는 점입니다.
편집: 내가 무엇을 하든 sdboot 속성을 재정의하지 않습니다. 내 uEnv.txt를 로드하는 것처럼(다른 이름의 장치 트리 blob을 올바르게 가져오기 때문에 작동함) sdboot 속성을 덮어씁니다.
이것은 내 uEnv.txt 파일입니다.
sdboot=if mmcinfo; then run uenvboot; echo Copying Linux from SD to RAM... && load mmc 0 ${kernel_load_address} ${kernel_image} && echo Copying Device Tree from SD to RAM... && load mmc 0 ${devicetree_load_address} ${devicetree_image} && echo Boot Linux kernel... &&bootm ${kernel_load_address} - ${devicetree_load_address}; fi
이것은 내가 얻은 로그입니다.

답변1
sdboot내 생각에는 실행 중이 uEnv.txt아니라 sdboot기본 환경에서 실행되고 있는 것 같습니다 .
Copying Device Tree from SD to RAM...이에 대한 증거는 로그 출력에서 볼 수 없는 것입니다.
끝에 다음과 같은 내용을 추가해 보세요 uEnv.txt.
uenvcmd=echo Copying Linux from SD to RAM... && load mmc 0 ${kernel_load_address} ${kernel_image} && echo Copying Device Tree from SD to RAM... && load mmc 0 ${devicetree_load_address} ${devicetree_image} && echo Boot Linux kernel... && bootm ${kernel_load_address} - ${devicetree_load_address}
물론 이것을 테스트할 수는 없지만 로그에 다음이 표시되어야 합니다.
Running uenvcmd ...
