Hello,

Please check TAS5825M EVM is well connected to PPCMB, and the PVDD is provided.

After that, try another PC to connect same EVM board. If still not working, then use Direct I2C to write below command:

w 98 00 00

w 9a 00 00

Capture the execute result.

Regards

change to another PC, Is Same problem!

2. What's the I2C result using below Direct I2C -> Script -> Execute?

In reply to Matthew Miao:

I have follow your request,

But the TAS5825M EVM 3.3V LED is not lighting.

What's the voltage measurement:

• 3.3V test point
• DVDD1 Jumper
• PVDD 

• 3.3V test point  --0V
• DVDD1 Jumper --0V
• PVDD --18V

Do you have another PPCMB or TAS5825M EVM board for cross check?

BTW, could you add external 3.3V to TAS5825M EVM test point and double check system connection?

It seems PPCMB 3.3V DVDD to TAS5825M EVM is not well connected. 

I Try to your step, but the issue is same,

Could we swap the EVM Board

I don't have any ppcmb,so i can not confirm, tas5826mevm damahe,or ppcmb damage。

How about below test:

BTW, could you add external 3.3V to TAS5825M EVM test point and double check system connection?
