How to build it
===============

Configure Buildroot:

    $ make versal_vck190_defconfig

Compile everything and build the rootfs image:

    $ make

Result of the build
-------------------

After building, you should get a tree like this:

    output/images/
    +-- boot.bin
    +-- boot.vfat
    +-- Image
    +-- rootfs.ext2
    +-- rootfs.ext4 -> rootfs.ext2
    +-- sdcard.img
    +-- system.dtb -> versal-vck190-rev1.1.dtb
    `-- versal-vck190-rev1.1.dtb

How to write the SD card
========================

WARNING! This will destroy all the card content. Use with care!

The sdcard.img file is a complete bootable image ready to be written
on the boot medium. To install it, simply copy the image to an SD
card:

    # dd if=output/images/sdcard.img of=/dev/sdX

Where 'sdX' is the device node of the SD.

Eject the SD card, insert it in the board, and power it up.
