DP83TD510E-PODL-EVM: 2.4Vpp mode2

Hi Allan,

Sorry for the late reply due to the holiday season.

May I ask which register did you configure when you are setting Test mode 2? Here is the script we use for test mode 2:

• 000d 0001
  000e 08f8
  000d 4001
  000e 4000 //Set test mode 2 in MMD 01

  000d 001F
  000e 001F
  000d 401F
  000e 4000 //soft reset

Could you try to see if adding soft reset after the test mode 2 configuration help?

Hi Hillman,

Thank you for providing the script for Test Mode 2.

I noticed the syntax for the Soft Reset section at the end seems to use Indirect Register Access (via Reg 0x000D / 0x000E) targeting MMD Device 31 (0x1F).

000d 001F
000e 001F
000d 401F
000e 4000 //soft reset

Since 0x001F (PHY Control Register) is a standard base register, shouldn't we access it directly? Using the indirect method for a standard register seems unusual.

Could you confirm if the following direct write is sufficient and safer?

001f 4000 // Soft Reset (Direct Access)

Or is there a specific reason we must access it via MMD 31 for this specific PHY?

Thanks.

Hi Wang,

You can also use direct register access for software reset. Both way work for to access the register 0x001F in MMD31 library.
