tcpip encx24j600的pic32mz和声问题

Heloi正在开发一个基于PIC32控制器和以太网控制器Enx24J600的定制板项目。我使用MPLABX IDE 3.40和Orthon 2.05和XC32，我的第一步是使用PIC32 MX795F512H和Enx24J600的演示应用程序（WebSoServer SD卡FATFS），这很好。第二步将是（SIM）。使用PIC32 MZ2048 EFH064改变处理器，但这不起作用。TCPIP初始化发生，但不结束（机器状态不继续）。所有的和声参数保持不变（除了时钟参数）。SPI接口工作正常，但以太网连接不发生。其他“演示”项目采用相同的结果：在PIC32 MX+Enx24上工作良好，不工作于PIC32 MZ+Enx24。硬件工作正常，它与一个旧版本的TCPIP堆栈工作正常。“TCPIP栈状态”始终保持不变。1（StasuStWORD），没有消息来自以太网端口。有人成功地尝试过类似的配置吗？PIC32 MZ EXX24J600（SPI模式）和声2.05？有什么建议吗？谢卫多

Hello
i'm developing a project on custom board, based on PIC32 controller and ethernet controller ENCX24J600.
i use MPLABX IDE 3.40 and HARMONY 2.05 and XC32
My first step was to use a demo app (web_server_sdcard_fatfs) with PIC32MX795F512H and ENCX24J600; this work fine.
My second step will be to (simply) change processor, using PIC32MZ2048EFH064; but this don't work at all.
TCPIP initialization take place but don't end (machine status don't go ahead). All HARMONY parameters remain the same (except clock parameters). SPI interface appear to work correctly but ethernet connection don't take place.
Other "demo" projects take the same result: works fine on PIC32MX+ENCX24, don't work on PIC32MZ+ENCX24.
Hardware work fine, it work correctly with an old adapted version of tcpip stack.
"TCPIP STACK Status" remain always 1 (STATUS_BUSY) and no messages come out from ethernet port.
Have someone successfully tryied similar configuration? PIC32MZ ENCX24J600 (spi mode) and HARMONY 2.05 ?
Any suggestion?
thanks
Guido

在您的MHC引脚图1中）检查以确保SPI引脚正确配置D2）检查以确保Enc8J60芯片选择线设置为GPIOOXOUT，复位线设置为GPIOIIN in您的MHC选项，Hyror框架配置，驱动程序，SPI1）确保SPI模块ID正确SELE。CTD。2）将时钟模式设置为DRVYSPIXCYDELMODIDIDLEWORYEDEGEFAL3）将输入相位设置为MyHC选项、Hyror框架配置、驱动程序、Enc2J601中的SPILIN输入、采样阶段，确保从选择中引用正确的PIN。TACK1）确保你在你的实例中引用Enc2J60。2）我也建议从你的网络启动标志中检查DHCP和DNS。3）确保ICMP服务器被选中。

以下为原文

In your MHC pin diagram
1) Check to make sure that SPI pins are properly configured
2) Check to make sure that ENC28J60 chip select line is set to GPIO_OUT and reset line is set to GPIO_IN

In your MHC Options, Harmony Framework Configuration, Driver, SPI
1) Make sure that SPI Module ID is properly selected.
2) Set Clock Mode to DRV_SPI_CLOCK_MODE_IDLE_LOW_EDGE_FAL
3) Set Input Phase to SPI_INPUT_SAMPLING_PHASE_AT_END

In your MHC Options, Harmony Framework Configuration, Driver, ENC28J60
1) Make sure that slave select references proper pin.

In your MHC Options, Harmony Framework Configuration, TCPIP Stack
1) Make sure that you referencing ENC28J60 in your instance.
2) I would also recommend unchecking DHCP and DNS from your network startup flags.
3) Make sure that ICMP server is selected.

请注意您的建议。我已经验证了配置，所有的都是正确的。请注意，我不使用Enc25J60，但EnC624J600。也注意到相同的项目/配置工作与PIC32 MX微控制器良好。我很想知道是否有人在使用TCPIP演示应用程序有积极的结果。使用PIC32 MZ控制器和Enx24J600的离子（或真实的TCPIP应用）…（和声）

tank you for your suggestions.
i had verified the configuration and all is right.
please note that i don't use ENC28J60 but ENC624J600.
also note that same project/configuration work fine with PIC32MX microcontroller...

I'm curious to know if someone had a positive result in using a tcpip demo application (or real tcpip application) using PIC32MZ controller and ENCx24J600... (and Harmony)

由于PIC32 MZ有内部以太网控制器，它不应该是默认的选择，所以我们不会在Engy分发中分发带有En24J600的PIC32 MZ演示应用程序。不管怎样，为了使您的项目取得一些进展，首先尝试对MAC或PHY进行一些熟知的读写操作。在EnC上注册，使用Project中的SPI驱动程序现在不调用TCP/IP堆栈初始化。如果SPI和I/O配置正确，那么所有读/写操作都会正常运行。否则，您可以调查问题所在。

以下为原文

We don't distribute a PIC32MZ demo app with the ENC24J600 in the Harmony distribution because the PIC32MZ has the internal Ethernet controller which should be the default choice.
Anyway, to make some progress with your project, try first to do some read/write operations of the MAC or PHY well known registers on the ENC, using the SPI driver in you project - daon't call the TCP/IP stack initialization for now.
If SPI and the I/O are configured properly, then all the read/write operations will perform properly.
Otherwise you can investigate to see where the problem is.

谢谢你的帮助。我现在把注意力集中在SPI通信上。通过示波器，我发现CS引脚（RC14）不能正常工作。原因是EnC驱动程序定义和设备配置之间的不一致性（SCOSEL被定义，因此RC14被保留为二级振荡器）。和声没有任何信号警告这种错位。现在我可以走了。谢谢。我的选择是En24，因为这个项目是一个进化。从以前使用Enc24的项目来看，我可以评估其他解决方案，但是我需要与低数量的线通信，比如SPI接口，和一个不太小的设备，因为我的板是手工制作的，并且我的芯片的最小间距必须是0.4mm（TQFP）。E？

thank for your help.
i have now focalized my attention on spi communication. with an oscilloscope i have discovered that CS pin (rc14) don't work properly. the cause is an incoherency between ENC driver definition and device configuration (SOSCEL was defined and thus RC14 was reserved for secondary oscillator).
HARMONY don't signal any warning for this misalignement.
now i can go ahead.
thank you.

my choose was for ENC24 because this project is an evolution from a previous project that use ENC24.
i can evaluate other solution, but i need a communication with a low number of wires, like SPI interface, and a device not too small because my board is hand-made and minimum pitch for my chips must be 0.4mm (TQFP).

what other PHY is suitable for this purpose?
