udp_ip_protocol_stack协议栈调用通信失败
使用的是MZ702N，例程ch33部分，没有使用接收部分，仅通过udp_ip_protocol_stack上传常数数据00ff，网络调试助手没有收数，求协议栈的正确调用方法...。prj仅顶层文件修改，如下：
udp_ip_protocol_stack udp_ip_protocol_stack

.app_rx_data_valid (),
.app_rx_data (),

.app_rx_data_last (),

.app_rx_port_num (),

进程部分以下屏蔽掉部分无效信号如下：

请问楼主解决了吗？是因为什么问题呀？
