Hi Noam,
Sorry I had attached the wrong file. Please check this and help me out. Thanks in Advance Gautam From: lwip-users [mailto:[email protected]] On Behalf Of Noam Weissman Sent: 23 October 2017 13:59 To: Mailing list for lwIP users Subject: Re: [lwip-users] Problem with TCP write. 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.

Hi Noam, Please find the attached file. Can you please help me out if you find anything not configured properly?

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. BR, Noam. From: lwip-users [mailto:[email protected]] On Behalf Of Gautam Kumar Sent: Monday, October 23, 2017 10:07 AM To: [email protected] <mailto:[email protected]> Subject: [lwip-users] Problem with TCP write. 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. Regards, Gautam
