1. RFS子卡JP2，短接pin2-3

2. 在Quartus Project的top中，将UART2USB 和WIFI_UART0连接

 assign WIFI_UART0_TX = UART2USB_RX;
 assign UART2USB_TX = WIFI_UART0_RX;
 assign UART2USB_RTS = WIFI_UART0_CTS;
 assign WIFI_UART0_RTS = UART2USB_CTS;
 assign WIFI_RST_n = KEY[0];
 assign WIFI_EN = 1'b1;

3. 编译后，烧录.sof

4. 开启ESPFlashDownloadTool_v3.4.2.exe，并选择“ESP8266 DownloadTool”

5. flash layout 參考： ESP8266_NONOS_SDK-2.1.0\bin\at\README.md

6. 其余设定参考下图，COM口选择RFS子卡的UART COM port：

7. 点击START，UART等待同步

8. 按一下FPGA版上KEY[0]進行同步

9. 下載完成
