kernel 6.5.4이미지를 이용하여 비글본 블랙보드를 출시하고 싶습니다 . 그래서 SDCard(8GB)를 가져와서 포맷하고 다음을 사용하여 2개의 파티션으로 분할했습니다.갈라진우분투의 응용 프로그램. 다음 부팅 파일을 SDCard의 BOOT 파티션에 복사했습니다.
- am335x-boneblack.dtb
- 마일로
- u-boot.img
- uEnv.txt
- uimage
kernel 6.5.4오류 없이 빌드 할 수 있었고 uImage 및 zImage 커널 이미지를 얻었습니다. 하지만 SDCard에서 내 보드를 부팅하기 위해 rootfs를 생성할 수 없습니다. 나는 다음을 사용하여 다운로드했습니다.뼈-debian-9.9-lxqt-armhf-2019-08-03-4gb.img.xz~에서
데비안 9.9 2019-08-03 4GB SD LXQT - 비글보드
먼저 압축을 풀어주세요

이는 우리에게뼈-debian-9.9-lxqt-armhf-2019-08-03-4gb.img문서
마우스 오른쪽 버튼을 클릭하고 "Disk Image Mounter"를 열어서 마운트합니다.
홈페이지/waageesh/rootfs
그 후 /home/waageesh/rootfs (비글본 블랙 이미지 파일에서 추출한 rootfs)의 모든 내용을 /home/waageesh/ROOTFS (SDCard에서 생성된 파티션, BBB에서 부팅할 때 rootfs를 커널로 복사)에 복사했습니다.
이제 SDCard에서 BBB 보드를 부팅해 보십시오.
SDCard에서 로드할 때 커널 패닉이 발생하고 중단됩니다. 이제 동일한 커널 버전에 대한 커널 모듈을 구축 중이며 SDCard에 있는 rootfs 파티션의 /lib/modules/6.5.4에 이러한 .ko 모듈을 설치하여 ARM 아키텍처를 교차 확인하려고 합니다.

uImage(커널 6.5.4) + rootfs(4.14.108-ti-r113) -> 커널이 로드되지 않음
uImage(커널 6.5.4) + rootfs(4.19.94-ti-r42) -> 커널이 로드되지만 오류로 인해 충돌이 발생합니다.SDCard를 고속 모드로 변경할 수 없습니다.&hang 커널 패닉 오류
내 의심은... 커널 버전을 기반으로 rootfs를 구축해야 합니까, 아니면 커널 부팅에 rootfs를 사용할 수 있습니까? (언급했듯이 이것은 나에게 효과가 없었습니다)
다음으로 다시 시도해 보세요.buildroot-2021.02.1Linux 호환 rootfs 를 생성합니다 kernel 6.5.4.
buildroot를 사용하여 동일한 버전으로 rootfs + 커널을 빌드하려고 시도했지만 결국 다음 오류가 다시 발생했습니다.

그래서 나는 막히고 혼란스러워졌습니다.
나는 단지 내가 원하는 특정 버전의 커널을 빌드하고 싶고 해당 사용자 정의 커널에서 rootfs를 생성할 수 있어야 합니다.
내가 놓치고 있는 것이 정확히 무엇이고 우리가 원하는 커널 버전에 대해 rootfs를 빌드하는 올바른 방법은 무엇입니까?
