C64x - Loop buffer exception - Missed stall

Hi,

I'm running on the DSP side of the OMAP device (Beagleboard) and from time to time I'm getting the below exception - 

3874   EXC_exceptionHandler: EFR=0x2

3875     NRP=0x82e63ec4

3876     mode=supervisor

3877   Internal exception: IERR=0x180

3878     Loop buffer exception

3879     Missed stall

What can be the reason? I'm using CCS3.3 (CGT - v7.0.4, BIOS - 5.33.06)

Many Thanks,

HR

    Hi,

    Despite the log messages seem to come from the BIOS System logs, I will forward your post to the OMAP forum thread as they will be able to better understand and explain the contents of the registers.

    Best regards,
