sun4i - Can't start /init (initramfs issue?)

  • Trying to get the MELE A1000 box up and running, the kernel panics when trying to start the early userspace: mybuild_klog.txt

    Code
    [    3.301289] Run /init as init process
    [    3.307300] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004
    [    3.314970] ---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004 ]---

    I built the image myself, from jernej 's mele branch (PROJECT=Allwinner ARCH=arm DEVICE=A20 UBOOT_SYSTEM=mele make image). I'm unable to confirm that the KERNEL file contains a valid initramfs. I have found initramfs.cpio among the build artefacts, and that does look like it should work:

    • /bin/sh links to /usr/bin/busybox
    • busybox present, compiled for 32bit ARM EABI5
    • /init script present

    Any suggestions how to troubleshoot this, or what else I should check?

    • Building whole image with DEBUG=yes?
    • Adding set -x at the very beginning of init and rebuilding an image with this change?

    I'm new to building LibreELEC, what would I need to clean to make either of these changes apply in the resulting image?
