I don't know if this is an issue specific to the 3.13 kernel, but
I have not seen this on 3.8.13. It appears whenever I attempt to
stop UVC video acquisition. I suspect it is something to do with
DMA vs. PIO. Please let me know if I should post this elsewhere,
or if this is the correct place.
Hi Dave,
Is this the classic white or black beaglebone?
Black
I'd try with disabling:
CONFIG_USB_TI_CPPI41_DMA
and enabling
CONFIG_MUSB_PIO_ONLY
That was the next thing on my list. I'll keep you posted.
The cpu will do all the transfers...
