Core crashes during Audio Play Back

Can you please confirm whether you are referring to any audio playback example which is available under ADSP-2159x BSP

 Let us know the rate of failure and confirm what is the sampling frequency you are using.

 To check the stack overflow. The compiler provides support for detecting stack overflows. You can enable stack overflow detection via Project > Properties > C/C++ Build > Settings > Tool Settings >CrossCore SHARC C/C++ Compiler > Run-time Checks > Generate code to catch a Stack.

 When stack overflow occurs at that time the stack overflow interrupt is triggered and also the "_adi_stack_overflowed" function is called by default. The stack is implemented as a circular buffer using I7. When stack overflow detection is enabled, the corresponding circular buffer overflow interrupt (CB7I) is enabled.

 Could you please check the status of the registers IMASK.CB7I and I7.

 We recommend to refer the section "Stack overflow detection" in the Compiler Manual for SHARC Processors linked below:

 Please note, SSOV bit is a sticky bit. Sticky bits do not clear themselves after the condition is no longer true. They remain "sticky" until cleared by the program. Interrupt service routines (ISRs) must clear their interrupt's corresponding sticky bit so the processor can detect a re-occurrence of the condition.
