USB Init fails on AHB Idle not set

Question asked by Pawlyk.James on Aug 29, 2016


I cloned a cube project for a working application with Micrium os.  I want to run code without an OS.  As far as I can tell so far I am doing all the same initializations but the function USB_CoreReset fails with a return of HAL_TIMEOUT.  (ignored by caller).   USB never becomes operational.  Not that both builds are running on same board.

Anyone have an idea of a string to pull to figure out what's going on?
