missing interrupts in same GPIO back on C6748

Other Parts Discussed in Thread: SYSBIOS

Hi Team,

Use case:  enabling interrupts for multiple GPIO pins on Bank3 causes interrupts to be missed.  Moving them to separate GPIO banks works ok.

 

From a hardware perspective it seems GPIO banks are mapped to a single event which can be associated with a CPU interrupt.  We believe that the interrupts are coming in so closely together that perhaps one is getting missed but nothing is reported on INXSTAT register.

We are trying to determine  if this is a SYSBIOS v 5.0  bug

Kind Regards,

Juan
