板子：smart4418
板子现在的内核：Linux version 4.4.49-s5p4418
板子现在的u-boot：U-Boot 2016.01-00032-geef57c7a47
我编译成功了2014.07版本的u-boot并成功生成u-boot.bin，然后使用fastboot烧写，过程如下：
****以下是在u-boot下的操作***
nanopi2# fastboot
fastboot - use USB Fastboot protocol
Usage:
fastboot <USB_controller>
- run as a fastboot usb device
nanopi2# fastboot devices
crq->brequest:0x0

在Windows下执行上面的命令后u-boot就出现了上面的错误：
GUID Partition Table Header signature is wrong: 0xEA000087EA000093 != 0x5452415020494645
get_partition_info_efi: *** ERROR: Invalid GPT ***

请问1：为什么我看维基教程进入fastboot的方式只需要输入命令fastboot就行，而我进入fastboot还需要在后面带个参数呢？
2：请问我这样烧写的方式是对的吗？烧写后出现的错误是什么原因导致的呢？
谢谢各位！
