Re: [lwip-users] problem with the DNS functions

[ake . forslund]

Hi,

When these kinds of delays help I ususally
find that a call that should block don't block, check the functions in
your sys_arch.c and verify that they work as lwip expects.

In 1.4.0 (and 1.3.2 I think) dns_init()
is called from lwip_init(). Wouldn't it be easier if your system ran the
standard init-sequence?

In my experience the error is usually
in my own code, the debug definitions *_DEBUG in lwipopts.h have time and
time again helped me locate my problems, if you haven't used them give
them a try. LWIP_DEBUG_DNS might be a good start.

Best regards

Without delay, the program execute dns_init and it remains in the file
"task.c".
With a delay inferior at 10sec, the program doesn't evolve.
I set this delay for to have the time to execute dns_init.

I find strange to have a delay here and especially superior at 10sec.

Thank you in advance.
