Hi,

Please refer to below User Guide for exact commands.

You may want to read back the register to confirm you have written the values correctly.

Hi Sirs,

Thanks for your reply.

Dear Eric

We tried Appendix B on your doc, use mii command to control.

mii write 0x05 0x001f 0x8000

mii write 0x05 0x0000 0x0140

mii write 0x05 0x0010 0x5008

mii write 0x05 0x0009 0x3b00

mii write 0x05 0x0025 0x0480

1000 Base Test Mode 1: Reg 0x001F = 0x8000 //reset PHY

Reg 0x0000 = 0x0140 //1000 Base-T Mode

Reg 0x0010 = 0x5008 //forced MDI Mode

Reg 0x0009 = 0x3B00 //Test Mode 1

Reg 0x0025 = 0x0480 //output test mode to all channels Reg 0x01D5 = 0xF508

 

It's same phenomenon. 0x0025 & 0x01D5 couldn't write! !!

Read 0x0025 is 0

1000 Base Test Mode 1:

Reg 0x001F = 0x8000 //reset PHY

Reg 0x0000 = 0x0140 //1000 Base-T Mode

Reg 0x0010 = 0x5008 //forced MDI Mode

Reg 0x0009 = 0x3B00 //Test Mode 1

Reg 0x0025 = 0x0480 //output test mode to all channels

Reg 0x01D5 = 0xF508  

So, does Address 0x0025 could be write?

Are you using extended address register read/write as provided in section 8.4.2.1 of DP83867 datasehet ?
