重启设备后IP地址会回落

设备：PIC32 MX运行TCPIP栈，USB控制台等其他无关的东西。我把IP地址硬编码成和谐并烧掉固件。该设备运行良好，并响应网络查询。如果我将PC与TeraTerm连接到USB端口，PIC提供管理控制台，在这里我可以执行以下命令来改变IP地址：“SEtiP PIC32 TIN 192.1680.32 255.255.255.0”，一旦我这样做，PIC现在被切换到新的IP地址。问题是当卡重新启动或电源循环时，IP地址回落到一个是硬编码的和谐。这是不好的。我们不可能通过每一张产生的卡片来协调IP地址。现场安装程序需要能够设置IP并拥有它。有人找到解决这个问题的办法吗？

    Device: PIC32MX running TCPIP stack, USB console, and other stuff which is irrelevant.

I hardcode the IP address into HARMony and burn the firmware. The device works fine and responds to network queries. If I connect a PC with TeraTerm to the USB port, the PIC serves up a management console where I can execute the following command to change the IP address on the fly: "setip PIC32INT 192.168.0.32 255.255.255.0"    Once I do this the PIC is now switched to the new IP address. The problem comes when the card is rebooted or power cycled, the IP address falls back to the one which was hard coded by Harmony.

This is no good. We can't possibly set the IP addresses through Harmony for every single card that gets produced. The field installer needs to be able to set the IP and have it stick. Has anybody found a solution to this problem?
