I don't have any means to read the debug values. When if i enable display functions, i won't have any means to "read" it.
Am i sounding confused? All i wish to say is that i don't have means like JTAG, etc. to read back any thing from my kit.
Regards,
AB

I expect you simply need to add more memory. Increase MEM_SIZE.

Enable LWIP_STATS in lwipopts.h, and call the stats display functions in
stats.h to get information about resource usage. The "max" values are
usually interesting.
Doing this allows you to increase the resources to quite high levels, try
running your application under typical loads, and then you look at the
"max" values to see how much was actually used, so you can reduce them back
down again.
