ISR Overrun - pramod mishra - Jun 23 9:02:53 2008
Hi All, I have made a model in Simulink ...for which I have generated code using 'Embedded Target using TI c6000'. My code runs on DSK6713. However as soon as the code starts running ...i get a error 'ISR Overrun - base sample time too fast' . and execution stops. Why is it so ? What is the remedy? Plz reply soon. Thanx in advance Pramod Mishra

pramod, Your description sounds like some interrupt is enabled, that interrupt occurs, the interrupt handler routine is not clearing the interrupt pending etc flags, the interrupt immediately occurs again. Also, the possibility that some interrupt source is initiating an interrupt event, that interrupt event is saved in the interrupt pending flag, The source of the interrupt goes away, the interrupt source occurs again, before the interrupt has been handled.
