PPC 임베디드 Linux 장치에서 최신 Linux 커널을 부팅하기 위해 U-Boot를 사용하려고 하는데 커널이 부팅되지 않습니다.
내 부팅 가능한 커널 이미지는 U-Boot에 의해 구축되고 네트워크 부팅됩니다. 문제는 커널의 압축을 푼 후에 아무 일도 일어나지 않는다는 것입니다. 무슨 일이 일어나고 있는지 잘 모르겠습니다. 누군가가 압축되지 않은 커널이 부팅 가능한 커널 이미지에 쓰고 있어 압축되지 않은 커널이 손상된다고 제안했지만 현재 발생하는 메모리의 전체 내용을 찾는 방법을 모르겠습니다. U-Boot의 출력은 다음과 같습니다.
Booting kernel from Legacy Image at 00800000
Image Name: Linux-4.9.48
Image Type: PowerPC Linux Kernel Image (gzip compressed)
Data Size: 3098594 Bytes = 3 MB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
그 후에는 아무것도 하지 않습니다.
왜 이런 일이 발생하는지에 대한 다른 아이디어를 갖고 있거나 uBoot의 메모리 맵을 어디서 찾을 수 있는지 아는 사람이 있나요? 미리 감사드립니다!
