TI中文支持网6678使用Broadcom的5464 PHY芯片。做了两块电路板，1.1版本和1.2版本。
使用论坛下载的K1 STK中的GE，对其寄存器配置做了修改，运行正常：
CPU CLK=312.5*3（CPU是1.25GHZ，已经降频使用了），DDR3 CLK 1312.5MHz。
[C66xx_0] JTAG ID= 0x1009e02f. This is C6678/TCI6608 device, version variant = 1.
DEVSTAT= 0x0000c001. little endian, No boot or EMIF16(NOR FLASH) or UART boot, PLL configuration implies the input clock for core is 50MHz.
SmartReflex VID= 63, required core voltage= 1.104V.
Die ID= 0x0b01000e, 0x0404251b, 0x00000000, 0x648c0021
Device speed grade = 1250MHz.

Initialize DSP main clock = 312.50MHz/1×3 = 937MHz
Initialize PASS PLL clock = 100.00MHz/2×7 = 350.000MHz
Initialize DDR speed = 312.50MHzx/5×21 = 1312.500MTS

再运行基于MCSDK的helloWorld改写的工程，DSP做服务器端，PC使用网络调试助手，直连向DSP发送数据。（DSP 跑NDK做服务器端有没有隐患？）
1.1电路板运行基本正常，PC端能重复发送数百MB数据。
1.2电路板运行异常，PC端无法ping通，无法connect。错误信息如下：

请问1.1版本和1.2版本有什么不同？

网络方面没有区别。
我的程序基于helloWorld例程，helloWorld.c文件的NetworkOpen处做了一些修改如下，会不会有问题呢？
//
// NetworkOpen
//
// This function is called after the configuration has booted
//
static void NetworkOpen()
{// Create our local server//hHello = DaemonNew( SOCK_DGRAM, 0, 7, dtask_udp_hello,//OS_TASKPRINORM, OS_TASKSTKNORM, 0, 1 );// commented fl,2017-12-05
//hHello = DaemonNew( SOCK_STREAM, inet_addr(LocalIPAddr), ZxjDspNetPort, ZxjC0Tcp201712,//OS_TASKPRINORM, OS_TASKSTKNORM, 0, 1 );// added fl,2017-12-05// fixed IP and PORT 2017-12-28
hHello = TaskCreate(ZxjC0TcpTskFxn,"ZxjC0TcpTsk",OS_TASKPRINORM, 32768, 0, 0, 0 ); // from CCS3 ndk, 2017-12-28

您有基于helloWorld的TCP例程吗？能否贴一个，谢谢！
另外，6678的网口是否只有1能用，0不能用？
谢谢！
Li Feng1：
回复 Shine:
TCP通信中，DSP作为服务器端，没问题吧？

附件是我的helloWorld，基于MCSDK的，添加了PHY(BCM5464)配置，链接文件、头文件来自压缩包的common文件夹。请指点，谢谢！
