TDA3XEVM: TDA3x - AR8031 Ethernet transceiver

Hello Anil,

What is software you are using? Is this VSDK?

With NSP you can use below APIs to access PHY registers.

GMACSW_ioctl( hGMACSW,
GMACSW_IOCTL_MDIO_READ_PHY_REGISTER,
(void *)&cmd, sizeof(MDIO_rdWrphyRegIoctlCmd));

GMACSW_ioctl( hGMACSW,
GMACSW_IOCTL_MDIO_WRITE_DP83867_PHY_INDIRECT_REGISTER,
(void *)&cmd, sizeof(MDIO_rdWrphyRegIoctlCmd));

Hi Prasad,

Thanks for the reply.

Yes I'm using vision SDK

Hi Prasad,

I would like to reset the rgmi clock and change the value of chip configure register(ar8031) after the tda3x evm booting.

I have gone through the file C:\PROCESSOR_SDK_VISION_03_04_00_00\vision_sdk\links_fw\src\rtos\utils_common\src\ndk\ndk_nsp_hooks.c in which most of the functions are called for tda2x.

May I know the files that needs to be changed for my usecase?Is there any other build procedure to be followed for these changes?

Regards ,
Anil

Hi,

Any update on this?

Hi Prasad,

I have tried writing a value to chip configure register.Build is successful.

After booting,I'm not getting any NDK link status.May I know what to done?

Hello Anil,

Do you want to use RGMII mode or RMII mode?
TI TDA3xx EVM has AR8031 PHY used in RGMII 1Gbit mode. Can you refer to that code in nsp_ndk_hooks.c file?

Hi Prasad,

By changing the mdio configurations in ndk_nsp_hooks.c,we can make it as 100Mbps Is this correct?

Anil
