Re: [lwip-users] Problem with TCP write.

[Noam Weissman]

Hi Gautam,

 

First of all you are not supposed to make changes in opt.h file…

 

For that you need to add lwipopts.h in your own code !

 

Have you started with an example or did you dive into it with seeing that a simple echo server is working ?

 

I suggest starting to read some documentations and continuing from there.

 

BR,

Noam.

Gautam,

 

Check err.h file !

 

/** Out of memory error.     */

  ERR_MEM        = -1,

 

You are doing something wrong in your code or did not properly defined your memory settings in lwipopts.h

 

If you show your code, it would help.

Noam.

Hi All,

 

I am using LWIP with ATSAME70. I am trying to send data over TCPIP, the port is getting opened successfully, but while send the data using TCP_Write(), it gives the error -1.

 

Please help me out in this regard.
