Thanks for the reply chrysn,
I am using No OS, I have inserted LwIP code into stm32L using IAR compiler,
my sys_now() is working fine as I am using Hardware Timer(Systick timer)
and it is producing proper milliseconds.
The problem--> sys_timeout() was calling handler function immediately. Is
fixed now.
I have now fixed the problem using sys_restart_timeouts() before
sys_timeout(), sys_restart_timeouts() sets back the timestamp of the last
call to sys_check_timeouts(). Thus after 1000 milliseconds, I get called
the handler function (Just what I needed).
I am using this timeout in getting Request Timeout prints in ping.c.
