# Generate Booting SD Card for VisionFive 2

## VFAT Image

Target: `starfive-visionfive2-vfat.part`

Step 1. Enter the command

dd if=/dev/zero of=starfive-visionfive2-vfat.part bs=512 count=131072
mkfs.vfat starfive-visionfive2-vfat.part

## SD Card Image

Target: `images/sdcard.img`

Requirements:

.
├── input/
│   ├── starfive-visionfive2-vfat.part
│   ├── u-boot-spl.bin.normal.out
│   └── visionfive2_fw_payload.img
├── genimage
└── vf2-genimage.cfg

Step 1. Build `genimage` from the [source](https://github.com/pengutronix/genimage/releases)

Step 2. Create `vf2-genimage.cfg`

image sdcard.img {
    hdimage {
        gpt = true
    }

    partition spl {
        image = "u-boot-spl.bin.normal.out"
        partition-type-uuid = 2E54B353-1271-4842-806F-E436D6AF6985
        offset = 2M
        size = 2M
    }

    partition uboot {
        image = "visionfive2_fw_payload.img"
        partition-type-uuid = 5B193300-FC78-40CD-8002-E86C45580B47
        offset = 4M
        size = 4M
    }

    partition image {
        partition-type-uuid = EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
        image = "starfive-visionfive2-vfat.part"
        offset = 8M
        size = 64M
    }
}

Step 3. Enter the command

./genimage --config vf2-genimage.cfg

## Flash the Image and Copy Files

Step 1. Flash the image to an SD card

sudo dd if=sdcard.img of=/dev/sda

Step 2. Copy the necessary files to the SD card

1. FIT image: `kernel.fit`
2. Configuration file: `vf2_uEnv.txt`

`vf2_uEnv.txt`

boot2=fatload mmc 1:3 ${loadaddr} kernel.fit; bootm ${loadaddr};
