Interface KSZ8863RLL to LPC54606

[sharads]

We have interface ethernet switch KSZ8863RLL to LPC54606. I have been using the driver available in SDK (it works well with LPCExpresso Eval board where LAN8720 is used). Off course, I have changed the pin mapping in pinmux accordingly. I am getting message like 'cannot initialise PHY'.

I understand that NXP is not having any driver for KSZ8863RLL.

Currently I am unable to understand what is going wrong. I am looking for kind of guidance that will help me going forward.

Hi, Sharad,

I suppose that you have to modify the fsl_phy.c and fsl_phy.h. I copy the screenshot here, you can see the two files:

I have checked the schematics of FRDM-K64F board, it use KSZ8081RNACA as PHY, I think you can download the SDK package for FRDM-K64 board and refer to even copy the files:fsl_phy.c and fsl_phy.h in FRDM-K64F SDK package.

This is the schematics of FRDM-K64F.

Hope it can help you

Hi XiangJun,

As per your suggestion, I have copied the fsl_phy.c and fsl_phy.h from

FRDM-K64F SDK package. I am getting lot of errors fsl_enet.c and

fsl_enet.h due to structural changes between FRDM-K64F and LPCExpresso

board/SDK.

I have copied the registers related to  KSZ8863RLL from fsl_phy.h

(FRDM-K64F SDK).

Unfortunately, I am not getting required value (PHY_CONTROL_ID1=0x22)

from following code..

    while ((idReg != PHY_CONTROL_ID1) && (delay != 0))

    {

        PHY_Read(base, phyAddr, PHY_ID1_REG, &idReg);

        delay--;

    }

what else I can check or do to make this working?

Your input will help me go further.
