DP83867IR: USB-2-MDIO always gives back "Error! Device not connected!"

Part Number: DP83867IR
Other Parts Discussed in Thread: MSP-EXP430F5529LP, USB-2-MDIO, MSP430F5529

Hello,

I am about to control the DP83867 with the MSP430F5529 Launch Pad (MSP-EXP430F5529LP) and the USB-2-MDIO Software.

 

I think the HW Setup is ok. IO Voltage set to 1.8V on Lanunch Pad, and supplied with 1.8V.

Connected MDC and MDIO from Launch Pad to the PHY. Installed Drivers and USB-2-MDIO Software on computer.

Flashed “USB_2_MDIO_F5.hex” to the Launch pad.

The USB-2-MDIO Software can be started. Baudrate and Port can be set.

After “Open Port” the status goes to “HW Connected”.

 

We set the PHY Address to 10 (1010b / 0xA) on our hardware. Then i selected PHY ID 10.

When a register (e.g. 0000) is selected and read is done i always get back the message:

“Register 0000 is: Error! Device not connected!”.

On the oscilloscope i can debug/see the data that is sent and received during communication.

And data seems to be correct on MDC and MDIO.

 

I also did write to the LED Control register 0x19 to switch on the LEDS.

I was able to control the LEDS by setting the Register 0x19. LEDS can be switched on and

of by writing the respective register values.

This shows that communication from PC to Launch Pad to the PHY device works.

But the USB-2-MDIO Software always shows the message “Register 0019 is: Error! Device not connected!”.

 

Also the “Find PHY ID” does not work. The response is

“PHY ID x is NOI available” where x goes from 0 to 31.

On the oscilloscope it can be seen that a response from the PHY is given when PHY ID 10 is checked.

 

When executing a script always the “Error! Device not connected!” is given back.

 

What could be wrong? Driver? UART Settings ?

 

We have Windows 7 professional 64-bit.

I did try to use another USB Port.

I did install everything on another computer (same OS)

 

Thank you very much in advance

 

Best regards

Christoph
