如何配置PIC32-EZ64

你好！抱歉我的坏英语我请求一些帮助，以便了解如何配置PIC32-EZ64，以便与LAN810一起工作。我的主要问题是：我多次尝试在这个板上使用TCPIP栈没有成功。这里我的说明：MPLAB X IDE V3.55和谐V2.BB板用于：PIC32-EZ64（OLIM）。使用PIC32 MZ2048 EFH064和LAN810AProject的板：“TCPIPSUDPULSE服务器”演示项目在和谐 V2Y02YY0BAppTCPIP“一般演示”演示项目中找到了以下主程序，我使用了“TCPIPSUDPUServer”演示项目中的和声。SK板（PIC32 MZ2048 ECH144）。现在，我想在PIC32-EMZ64 OLIMEX板上运行这个项目。由于和声，我改变了设置，以支持PIC32 MZ2048 EFH064。但是没有以太网端口的通信。我试图ping板，没有答案（与WiReSurk无关）。通过调试，我发现TCPIP栈初始化没有运行。在App.c文件中，TCPIPSATAT＝APPyTCPIpl忙了好几次，在AppyTCPPIpError上完成了阻塞。为了验证以太网端口是否在我的板上工作，我从OLIMEX网站上下载了一个演示项目：De将军。MWHEN通过直接在这个演示中使用.HEX文件找到程序板（由于MPLAB IPE），以太网端口工作。我还没有尝试更新这个演示中的文件，该项目使用了一个旧版本的MPLAB，并且似乎需要大量的工作，以便在我的版本上重新读取代码。NKS我的问题是微控制器和以太网TrimeEIR（LAN810A）之间的配置。和声没有用于810A的外部PHY选项，但是在OLIMEX“一般演示文件”中，它似乎使用了与LAN820（….Demo DemoV1Y06Y02\Frase\驱动程序）相同的PHY选项。因此，通过LAN820PHY选项，我尝试了，没有成功地发现如何通过协调和文件内的配置来改变配置，以便使以太网端口工作。我想得到一些我错过的建议。谢谢，Endinar。

    Hi !
Sorry for my bad english

I request some help in order to understand how configure the PIC32-EMZ64 in order to work with the LAN8710.
My main problem : I tried several times to use the TCPIP stack on this board without success.

Here my specs :
MPLAB X IDE V3.55
HARMONY V2.2b

board used : PIC32-EMZ64 (OLIMEX) board with PIC32MZ2048EFH064 and LAN8710A
project used : "tcpip_udp_server" demo project in harmonyv2_02_00bappstcpip
                     "General Demo" demo project found here

As main program, I use the "tcpip_udp_server" demo project found in harmony.
I already tried this project with success with the PIC32 EC SK board (PIC32MZ2048ECH144).
And now, I would like to run this project on the PIC32-EMZ64 OLIMEX board.

Thanks to harmony, I changed the setting in order to support the PIC32MZ2048EFH064.
But there are no communication by the ethernet port.
I tried to ping the board, no answers (with Wireshark nothing comme out).

By debugging I found the TCPIP stack initialisation doesn't run.
In the app.c file :
switch(UDP1_appData.state)
    {
        case APP_TCPIP_WAIT_INIT:
            tcpipStat = TCPIP_STACK_Status(sysObj.tcpip);
            if(tcpipStat < 0)
            { // some error occurred
                SYS_CONSOLE_MESSAGE(" APP: TCP/IP stack initialization failed!rn");
                UDP1_appData.state = APP_TCPIP_ERROR;
            }
tcpipStat = APP_TCPIP_BUSY several times and finish blocked on APP_TCPIP_ERROR.

Just in order to verify if the ethernet port work on my board, I dowloaded a demo project from the

OLIMEX website : General Demo
When I program the board by using directly the .hex file find in this demo (thanks to MPLAB IPE), the ethernet port work.
I have not yet tried to update the files in this demo, the project used an old version of MPLAB and seems to need lot of works in order to readapt the codes on  my version.

I thinks my problems is the configuration between the microcontroller and the ethernet transceveir (LAN8710A).
Harmony doesn't have an external PHY option for the 8710A, but in the OLIMEX "General Demo" files it seems to use the same PHY option than the LAN8720 ( ..General demov1_06_02frameworkdriverethphysrcdynamic).
So, with the LAN8720 PHY option, I tried, without success, to found how to change the configuration by Harmony and inside the files in order to make the ethernet port works.

I would like to get some suggestions of what I would have missed.

Thanks,
Endinar
