I am using lwip on a TI LM3S6965 without RTOS.
I have a web page with 12 checkboxes and a couple of select lists within a form
that is handled by a CGI handler in the program.
I know that a checkbox only sends data when it is checked.
If I check all 12 boxes and press the submit button the page immediately
shows an error. "unable to display page" and the CGI never gets called.
If I only check 10 or less boxes the CGI gets called and all is fine.
I have tried increasing MEMP_NUM_PBUF to 36 and increasing MEM_SIZE to 24K in
the lwipopt.h file.
But it didn't help. I suspect it has something to do with memory.
Is there any other param or setting I should check?
Here is the HTML code:
