Other Parts Discussed in Thread: DP83TD510E

Hello,

I would like you to confirm about following two for EVM setting. Could you confirm about below and give me feedback ?

* When I shunt J9 to use "USB Power Supply Option", can I NOT use USB2MDIO tool ?
=> When I try to perform "USB Power Supply Option" setting, USB serial device is not recognized on PC. So I ask above question.
* When I use "USB Power Supply Option", can I use both DP83822 and DP83TD510E ?
=> Since LED0 to 2 does not light up, so I ask above question

Hi Ryuuichi,

Can you try replacing R24 on the EVM with a 0 ohm resistor and see if that fixes your issue?

Hello Kam-san,

Do you mean that I need to replace resistor from 33ohm to 0 ohm ?

Hello Kam-san,

Sorry for my late response.
I had no chance to check this, but today I could check this.

Aa ar result, I confirmed USB2MDIO tool work correctly by replacing R24 from 33ohm to 0ohm.
I also checked there is no impact when I use external power supply as well. So this may be proper workaround for this issue.

Thank you.
