BeagleBone Black에서 Falcon 모드를 활성화하려고 할 때 U-Boot 오류가 발생합니다.

BeagleBone Black에서 Falcon 모드를 활성화하는 데 문제가 있습니다. 작동 중인 U-Boot(v2019.04) 및 Linux(Debian 11.5, 커널 v5.15.65-bone-rt-r30)가 있지만 지금까지 Falcon 모드를 성공적으로 활성화하지 못했습니다. 여러 가지 오류가 발생했습니다. 첫 번째는 환경을 보호하려고 할 때입니다.

** Unable to use mmc 0:1 for saveenv **

두 번째는 SPL을 내보내려고 할 때입니다. uImage 헤더를 올바르게 읽습니다.

튜토리얼을 따라하고 있어요https://embetrix.com/2017/05/07/fast-boot-linux-with-u-boot-falcon-mode/(Ubuntu 서버에서 모든 것을 컴파일하고 Debian의 BeagleBone Black에서 SD 카드에 직접 썼다는 점을 제외하면 Yocto에서 5개의 "부분" 명령이 포함된 부분을 건너뛰었습니다. 문제가 아니기를 바랍니다.) 가능합니다. 튜토리얼이나 내 환경 어딘가에 버그가 있다는 것입니다. 커널을 읽는 데 시간 초과 문제가 있거나 장치 트리 파일이 잘못되었을 수 있습니다. 작동 중인 zImage에서 uImage를 생성했는데 uImage 헤더가 올바르게 읽혀지고 있어 문제가 무엇인지 잘 모르겠습니다. 어떤 도움이라도 대단히 감사하겠습니다.

편집: 아래 제안된 대로 더 이상 EXT4 파일 시스템을 사용하지 않도록 구성을 변경했습니다. 이제 내 환경 변수가 저장되었습니다. 정말 좋습니다! 불행하게도 커널 체크섬 문제가 여전히 존재합니다. 현재 U-Boot 로그는 다음과 같습니다.
