Proxmark3 小白入门 | 更新Proxmark3 固件

系统环境：macOS Mojave version 10.14.2

用 Proxmark3 客户端连接 Proxmark3

$ proxmark3 /dev/cu.usbmodem*****

固件版本也太老了吧！5~6年前的？OMG！让我来更新一下。

1. 下载源代码

git clone https://github.com/Proxmark/proxmark3.git

2. 编译 bootrom, OS and software

cd proxmark3
make clean; make

3. 断开 Proxmark3 连接。然后按着Proxmark3上的按钮重新连接到电脑。 当看到橙色和红色灯亮了之后，就可以松开按钮。
4. 查看 Proxmark3 的设备名

 ls /dev/cu*

类似这样 /dev/cu.usbmodem*****，就是 Proxmark3 设备名

5. 更新 bootrom, FPGA and OS:

$ ./client/flasher /dev/cu.usbmodem**** -b bootrom/obj/bootrom.elf armsrc/obj/fullimage.elf
