Re: [lwip-users] LPC1788 Ethernet Based Socket Communication Randomly Stops Working After Few Hours

[Jeffrey Nichols]

    Hi Pratap,
    
    Make sure the integration between FreeRTOS and LWIP treats any timer
    conversion correctly. If it overflows at the same time as you lose
    connectivity then this is your problem. In my experience about half
    of the examples provided by silicon vendors have gotten this wrong.
    
    Another other likely possibility is running out of memory, which you
    may be able to quickly trigger by pointing a port scanner (e.g.
    nmap) at your device.
    
    If you can attach a debugger to your device while it's running you
    may be able see what's happening when things go wrong.
    
    Regards,
    Jeff

Hi,

 

We are using LPC1788 OEM Board REV E.of Embedded Artists.
We are using MCUXpresso IDE V11.3.0 and FreeRTOS Lwip stack.

 

The FreeRTOS  version is  "V7.5.3".

 

The LWIP version is

 

 

This Board uses a socket communication to communicate with other board at 1ms time interval.
Randomly after few hours the LPC1788 Board stops working so The socket communication also  stops.

 

Please help us to resolve the issue.

 

Thanks and Regards,

Pratap Devsarkar.
