Hi,

I am using EVM 6474 and DSP/BIOS, and my application runs on CORE0.

I have three interrupts configured,

1. Mcbsp Receive ready interrupt.

2. Gpi interrupt

3. IPC interrupt.

When I enable the PRD module (i.e. Use CLK Manager to run PRD), the core 0 crashes and goes to Exception handler.

below is my observation on Message LOG,

=============================

817 TSK: running dynamic TSK (0x008018dc)

818 SWI: end KNL_swi (TSK scheduler) (0x874e10) state = done

819 CLK: current time = 125 (0x0000007d)

820 PRD: tick count = 125 (0x0000007d)

821 SWI: post KNL_swi (TSK scheduler) (0x874e10)

822 SWI: begin KNL_swi (TSK scheduler) (0x874e10)

823 EXC_exceptionHandler: EFR=0x2

824 NRP=0x10000

825 mode=supervisor

========================================

but. when i disabled PRD module from using the CLK Manager, It is working fine.

can u please help me on this.?

Thanks,

Bala

Bala,

I noticed that this post was never responded to -- did you ever resolve the issue?

And what version of BIOS are you using?

It appears that your PRD is actually functioning correctly. If the PRD is disabled, does that mean the SWI is never posted? If so, it would appear that something in the function invoked by the SWI is triggering an exception. What is that function doing?
