    P.Mutasingwa
    De-bouncing for the GPIO lines was turned off. I turned off various peripherals in the system and was able to narrow down the cause to the gp-timer interrupt. If I mask this interrupt, the jitter disappears. This is the GPTIMER12 on the OMAP. When this interrupt runs it shows up as IRQ-95 in...
