Could anyone help me get started with minized ?

matgoszcz

Hello,

 

 

first of all, I would like to be able to upload programs written in vhdl.
I don't know how to create correct constraints file.

 

Thanks for the help in advance

  • Hi, do you know what default file system eMMC has?. I want to read image.ub from eMMC but it says that it can't read file system.

    If the MiniZed is brand new and the eMMC has never been used, it will need to be partitioned and formatted.  The PetaLinux BSPs provided by Avnet for the MiniZed include a shell script (format_emmc.sh) to create and format a small (128MB) DOS partition.

     

    The PetaLinux BSPs for MiniZed can be found here:
    MiniZed

    The shell script looks like this:

    #Delete partition and add a new one of 128MB

    echo "fdisk /dev/mmcblk1 (1 partition of 128MB)"

    echo -e "d

    o

    n

    p

    1

    1

    +128M

    w

    " | fdisk /dev/mmcblk1

     

    echo "sleep 1"

    sleep 1

     

    #Format as a DOS partition

    echo "mkdosfs -F 32 /dev/mmcblk1p1"

    mkdosfs -F 32 /dev/mmcblk1p1

     

    echo "sleep 1"

    sleep 1

     

    #Mount eMMC

    echo "/dev/mmcblk1p1 /mnt"

    mount /dev/mmcblk1p1 /mnt

    echo "ls -l /mnt"

    ls -l /mnt

     

     

    #Unmount drive again:

    echo "umount /mnt"

    umount /mnt

     

    NOTE!  You may want to use fdisk first to verify the eMMC is indeed empty.  Creating a new partition table and formatting a new partition will destroy any data already on the eMMC.

    Thank you, Tom!

     

    I have managed to run my minized (again) on Petalinux 2019.2. I just have one more question, do you know what petalinux package is required to have "mkdosfs"?.

    I bypassed this issue by flash programming with minimal bootable version from restoring minized tutorial but still I would like to know.

     

    Thanks.
