But the TRM seems not to disclose the location of this register. Some googling indicates that the L3/L4 interconnects are documented elsewhere.
OTOH, I am still wondering if my kernel isn't the root cause. It seems clear that other people have been able to get ADC control from the PRU, but with 3.8 or 4.1 kernels. I could revert to an older kernel version, but that feels like the wrong approach. I have also been looking at the IIO system, which may be a better approach as it would be more "standard" and portable than using the PRU. (But I *like* using the PRU - it's a nice hammer looking for a nail!) -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
