I am working on lpc 1833 microcontroller and have ported lwip stack on it. Also i am able to ping successfully to my device from other device. Now i have added one task in which TCP server created and accept multiple connection of clients. This works fine means packet send from client successfully received at server and vice versa. After that i have added another 2 task and above tcp server task not working means unable to send/receive tcp packets. If i comment those 2 tasks then it's working fine.

See my code in attached file here.

Any idea whats wrong here?

Regards,

Jayesh

Hi, jay,

I would check the following:
1. make these two new task as empty task and see if the TCP is still working. Add in your two new tasks back in with small steps to see what is causing the TCP stop functioning.
2. memory conflict and timing conflict investigation.

regards,
