急!c6678的UDP通信问题



我在6678的EVM板运行了D:\ti\mcsdk_2_01_02_06\examples\ndk\helloWorld的程序,实现了6678与PC机的UDP通信,但是一次收发的数据量远远不够。目前测试了只有1436个字节,我尝试在helloworld.c中将rc的值作修改,可是不管是8192还是16384,都无法改变实测的一次收发量。还望各位指点!

// UDP Receive limit
rc = 8192; //试问是8192个字节还是什么?
CfgAddEntry( hCfg, CFGTAG_IP, CFGITEM_IP_SOCKUDPRXLIMIT,
CFG_ADDMODE_UNIQUE, sizeof(uint), (UINT8 *)&rc, 0 );
