水星2程序员
mercury2_prog应用程序是一种命令行实用程序，用于通过板载FT2232H USB到串行适配器编程Mercury 2 FPGA板。目前，它可以与S25FL116K（16Mbit），S25FL132K（32Mbit）和S25FL164K（64Mbit）SPI闪光芯片进行通信。
该应用程序使用FT2232H的端口A用于配置。端口B免费用于用户应用程序。请参阅Mercury 2示意图，以了解如何将FT2232H连接到FPGA和SPI闪光灯。
用法
-h或--help打印了描述这些选项的帮助消息-l或--list列出了所有可见的FTDI设备，并尝试找到Mercury 2板-e或--erase在水星上擦除了整个SPI闪光2-
-r或--read读取整个SPI闪光灯并将其保存到dump.bit -
-w或--write使用指定的文件将其写入SPI闪存。例如：./ mercury2_prog -w test.bit。 （请注意，此命令将在编写之前自动删除所需的块。）
建造
mercury2_prog应用程序是在Linux上使用make编辑的。使用GCC 7.4.0和MingW32-GCC-7.3在Ubuntu 18.04上进行了测试。该构建产生了两个二进制文件：
-
mercury2_prog本机X86-64 Linux应用程序 mercury2_prog .exe跨编译X86-64 Windows应用程序
请注意，您必须sudo apt-get install mingw-tools mingw-w64-tools以互编换窗户。
