Other Parts Discussed in Thread: DP83849I, , MSP-EXP430F5529LP

Hi

I'm doing an Ethernet communication test with the DP83849IVS-EVK board.

I want to modify the register for changing to LED mode 3

I have  "MSP-EXP430G2ET" LAUNCH PAD  and  read "usb-2-mdio software tool" (SNLU 197)

I am trying to run USB-2-MDIO using the MSP-EXP430G2E2 Launchpad and the DP83849IVS-EVK board.

but I have problems with PHY searching.

My conditions is 

 1) Connected

   : DP83849IVS-EVK  MDIO/ J1 Pin2  ---- MSP-EXP430G2E2 board MDIO / P1.5

     DP83849IVS-EVK  MDC/ J1 Pin5  ----  MSP-EXP430G2E2 board MDC / P1.4

     and GND PIN connected

 2) On the MSP-EXP430G2E2 board

  : the drivers are installed

  : successfully flasehd, down to Launchpad and LED1 and LED2 of fully illuminated

   ( file: usb_2_mdio_G2.HEX)

 3) On the DP83849IVS-EVK board

 :  J36 (PHYAD1) and J37(PHYAD2) => strapped high or open

 4) On USB-2-MDIO

 :  PORT can be opened, 

    Port Port Status window display "green" and "HW Connected" on "USB-2-MDIO"  program

However , when I run the "File -> find PHY ID" , all 32 PHY IDs show "NOI Available"

Could you tell me any idea or what problem?

Thanks 

Donell
