Original question:

RM57L843: Ethernet sample codes

RM57L843: TCP/IP sample code

Part Number: RM57L843

Hi,

My customer downloaded LwIP example from the original post.
https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/997216/rm57l843-ethernet-sample-codes/3683890#3683890

Now, he is trying to implement it. RM57 is client and PC is server.
What he calls are below functions and order.

tcp_new() => tcp_connect() => tcp_write() => tcp_output()

All these functions return with OK, but no data are sent to server.
Customer guesses something is missing.
Do you have TCP/IP sample code using LwIP stack?

Thanks and regards,
Koichiro Tashiro
