Hi,
   My target is Arm pid(simulator only) and using sid.
                  I am not at all enabling or disabling any
interrupt.How to check interrupt is enabled or disabled. 
    Both ISR and DSR are called till the first alarm is triggered.
    After first alarm,when i initialize second alarm,ISR and DSR are not
called at all,but alarm is being added.
  Thanks and Regards
Mahesh

Re: [ECOS] stops at start function

[mohanlal jangir]

Are you using cyg_alarm_initialize? This needs a non-zero third argument for
further trigger. Otherwise it will only trigger once.

Do you mean, when your first alarm is triggered, the ISR registered is not
called!! If I understand your query properly, I would suggest you to check
following -
1. You are registering ISR, with cyg_alarm_create
2. Make 4th and 5th argument of cyg_alarm_create "global static". (Basically
I want to make sure, that valid memory is allocated for those arguments).
3. Make sure your alarm is really triggered. Can you send the code snippet,
which is creating and initialising the alarm?

Mohanlal

[ECOS] thanks for the support Re: [ECOS] stops at start function

[Mahesh]

Hi,
    I got the error in my problem.
    I had allocated a pointer to a structure,but in this particular
flow,it missed the assignment of address of structure to the pointer and
hence the pointer was pointing to 0x0.
    It was changing this address contents and hence getting stuck.
Thanks for the support the group gave to me.It was really a good
experience.
Once again thanks all
Thanks and Regards
Mahesh
