Hello,

I am getting a runt pulse out of the PXA270 when the frame and s-clock first go active and the output is switching from high-low-high. The runt pulse is only low for 1/2 cycles.

Configuration: BitsyXb to Ti DSP 320-6713 over spi0, failure occurs at spi clock @800 KHz, gets worse when clock rate increased.

Don't know if this is really causing the failure but doesn't look good. Should there be some timing relationships between the frame-clock-data?

BitsyXb

help.

Hi John, this problem has not been reported before on any of our systems. Can you contact us with more details about your test procedure and the OS you're using on BitsyXb? Thanks.
