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
