Hi,

You are getting an abort exception. HSV thread is the HTTP server thread. I think the abort exception may be due to a stack overflow, but I am not sure about that and I don’t know how to check it.

I have usually found that error to be due to uninitialised variables in the webpage\_v.c file - typically because I haven’t ‘fleshed out’ the stub routines generated by PBuilder (and sometimes because of bugs in my routines)

Thank you steved, you helped me solve my problem.

I was also having an abort problem. I am using a function to get the string type data to fill in a form, I was reading it from NVRAM and, due to an error, it was not ‘\0’ terminated. That caused my system crash.
