PHRAM 장치(dev/mtdblock0)를 rootfs로 사용하여 RAM에서 yocto로 구축한 비지박스 기반 ext4 Liunx 이미지를 부팅하려고 합니다. 이 머신은 Intel FPGA 보드(Stratix 10)입니다. PHRAMLinux 커널 구성에서 활성화했습니다 .
커널, 장치 트리, rootfs를 RAM에 로드하고 수동으로 부팅했습니다. (uboot가 없으면 reg x0-x3을 설정하고 EL1의 커널로 점프하세요.)
커널은 mtdblock0rootfs로 성공적으로 마운트되었지만 systemd 중에는 실패합니다.
편집하다:systemd 대신 /sbin/init로 sysvinit를 사용해 보았는데 훌륭하게 작동했습니다. 따라서 문제는 systemd에 있어야 합니다. 하지만 시스템이 필요합니다.
이미지는 원래 MMC 카드에서 부팅하도록 설계되었으며 제대로 작동하므로 수정해야 할 것이 있는지 궁금합니다.
이것이 로그입니다. (저는 rootfs를 마운트한 후 복사했습니다. 필요한 경우 커널 부팅에서 해제합니다.)
