Few day ago, i asked a question " How can i use to lwIP at RTOS "

e2e.ti.com/.../799670

and QJ Wang gave me a solution. but it worked on only HDK board.

I want to use this code on LaunchPad Board.

if I used this code on launchpad, i think it doesn't receive signal like MDIO ACK .etc

What can i do for it work well on LaunchPad ?

Plz Help me.

I changed Input PINMUXING from Alternate to Default in HALCOGEN. bcuz i use LaunchPad.

and changed ECLK configuration. If i use ECLK Pin Mode to GIO, MDIO couldn't read PHY ALIVE.

and now, I can't get Link status.

MDIO_LINK register always 0. How do i fixed it?

I resolved this problem!!
LaunchPad's GIOA[3] , GIOA[4] are work as switch at dp83630 !
I found it in schematic. so, i set gioA[3], [4] to output.
then, PING TEST works well.
but i got a another problem.
SCI doesn't work and User LED(GIOB [6], [7]) Blink too..... why they don't work??

Hello Donghun,

The baudrate and number of stop bit may be different in two setups. HDK uses NHET pins for LEDs rather than GIOB[7:6].
