Hi,
This is continuation of my previous post.
What I observed is, after 26packtes,
lwip_cheksum function is called. Inside this function, pbuf’s next pointer is
taken, but this next pointer is pointing to some junk value (either corrupted
or not initiliazed), so it goes to exception handler.
Can you plz suggest any method, to further
debug this issue.
Regards

Are you using lwIP with the driver provided by Analog Devices,
therefore are you using the VisualDSP Kernel (VDK) ?

Hi,
I don’t see that program is crashing.
After 10 packets sent, if I keep the breakpoint at sio_write, it is hitting.
And after some time, breakpoint at pppInproc is also hit.
If I allow the code to run, by removing
breakpoint and after some time, if I insert the breakpoints again it is not
hitting. But the code is not crasing.
