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?
