~# /tmp/vpd_tool -r -H -O "/sys/bus/i2c/drivers/at24/8-0050/eeprom" -R VINI -K B4
{
    "/sys/bus/i2c/drivers/at24/8-0050/eeprom": {
        "B4": "0x00"
    }
}
~# /tmp/vpd_tool -r -H -O "/sys/bus/i2c/drivers/at24/8-0050/eeprom" -R VINI -K B3
{
    "/sys/bus/i2c/drivers/at24/8-0050/eeprom": {
        "B3": "0x000000000000"
    }
}
~# /tmp/vpd_tool -r -H -O "/sys/bus/i2c/drivers/at24/8-0050/eeprom" -R VINI -K B7

        "B7": "0x000000000000000000000000"
    }
}
