I do not have access to a 3530 Beagle
Just tried on 3630 beagle that seems to be fine.
let me see if I can reproduce in other onap3 boards that I have.
Hi Paul,
On my beaglexm 3630
This is with the following steps:
1. merge your 32k timer fix branch
2. disable USB host: set CONFIG_MFD_OMAP_USB_HOST=n
Let me know if I missed anything.
