Hello DongHun,

I am working on an example of lwip+freeRTOS, but I haven't make it work. I will keep you informed after I complete.

Hello DongHun,

Attached please find the working example of freeRTOS + LWIP (webserver) on TMS570LC43x HDK. This projects contains two tasks: one is for LWIP+LED blinky, other task is for another LED blinky.

The project works for both static IP (commented out) and dynamic IP (DHCP).

Hi QJ.

I tried to doing your solution and modified some link setting, lib path .etc for me. but it didn't work.

so I have tried to solve this problem all day but i couldn't.

Putty show me message "ERROR INITIALIZING HARDWARE".

LED blink was work very well.

I don't know why it doesn't work.

Please let me know if you have any guesses.

Hi QJ!

I think I solved the connection deny.

I think It has a bug in netif.c

If code attach ' if (init(netif) != ERR_OK) ' it doesn't work. so i inserted // in front of that code. then It works well. And finally i got a IP.

Thank you !
