PHY changing question

[M_Grillo]

Hello,

What are the steps for changing from the "phy_ksz8041.h" PHY to the “phy_dp83xxx.h” PHY in an MQX project?

MQX 3.4

CW 7.1.2

Thanks,

Mark

Mark,

even if not stated, but from compiler you are using I suppose you would like to modify some MCF5225x  BSP.

1. In BSP library Peripheral IO Drivers -> enet-> phy replace files "phy_ksz8041.*"  by  “phy_dp83xxx.*” 

2. In enet_ini.c change included files

//#include "phy_ksz8041.h"

#include "phy_dp83xxx.h"

3. Modify ENET_IF_STRUCT ENET_0 struct to refer to phy_dp83xxx_IF

const ENET_IF_STRUCT ENET_0 = {     

&MCF5xxx_FEC_IF,     

&phy_dp83xxx_IF,     

MCF5225_FEC0,     

MCF5225_FEC0,     

BSP_ENET0_PHY_ADDR,     

BSP_ENET0_PHY_MII_SPEED

};

I am not sure if there was MQX 3.4  BSP_ENET0_PHY_MII_SPEED parameter in structure. If not, delete it.

When you recompile BSP and it should work.

The BSP and all other libraries compiled fine but now the application has this link error:

Error   : Undefined : "phy_dp83xxx_IF"

Referenced from "ENET_0" in

Link failed.

Thanks,

Mark,

sorry I have missed couple of things.

My web_hvac application was possible to compile without problems.

But if you are accessing  phy_dp83xxx_IF structure in your application you need to change also following.

in bsp.h change

//#include <phy_ksz8041.h>       // Ethernet Physical Interface

#include <phy_dp83xxx.h>       // Ethernet Physical Interface

in BSP postbuild batch file "bsp_twrmcf52259.bat" change 

rem copy /Y ..\..\..\mqx\source\io\enet\phy\phy_ksz8041.h .

copy /Y ..\..\..\mqx\source\io\enet\phy\phy_dp83xxx.h .

That did it!

Thanks! It's much appreciated.
