zedboard embedded linux version

e14 Contributor

Hello,

some questions about the pre-installed linux:

1) Is this embedded linux version that from the linux-xlnx xilinx-git repository?

http://git.xilinx.com/?p=linux-xlnx.git;a=summary

2) Do you supply all sources, build scripts and project files, or do I have to struggle through the xilinx documentation to get it working for my own project?

- Or do you supply only the working binary of the linux-system?

3) Do you supply the planAhead and EDK Project Files for the zedboard?

    hi,
    my command string says:
    console=ttyPS0,115200n8 earlyprintk rootfstype=ext4 root=/dev/mmcblk0p2 rw rootdelay=1 init=/sbin/init
    also i had to set the CONFIG_CMDLINE_FORCE parameter in order to avoid passing parameters to the kernel using u-boot.
    C.

    Hello,

    Had anyone finally solved the kernel panic problem/s?

    It happens me the same, I'm trying to build my own embedded linux distro. using u-boot as a bootloader, digilent kernel (new kernel uploaded in their git, based on 3.6 kernel), *.dtb obtained with the script tools as xilinx "explain" in his wiki page (I kept bootargs like the out of box factory made) and Bootloader too, (I'll post something soon about my bootargs' discoveries), I use buildroot 2011.11.1 to compile the kernel and to build my root filesystem image with the basic libraries.

    Copying *.dtb, zImage, ramdisk.image.gz and BOOT.BIN to SD and powering up. When the filesystem begins to being mounted:

    >EXT4-fs (ram0): mounted filesystem without journal. Opts: (null)
    >VFS: Mounted root (ext2 filesystem) on device 1:0.
    >Freeing init memory: 148K
    >Failed to execute /sbin/init.  Attempting defaults...
    >Kernel panic - not syncing: No init found.  Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.
    >CPU0: stopping

    And then it hangs. If I try my zImage with the other factory made files of the SD it works.

    Im trying different combinations of uClibc versions, binutil versions, and GCC versions inside buildroot, could somebody help me?

    If anybody need some more info or had any idea please answer or mail me, Im running out of ideas.

    Thanks for your time. Best regards,
