Hi, I am working on adding USB OTG host support for the mx31_3ds board (OTG PHY is a ISP1504). USB OTG in device mode works fine and I can only get OTG host mode to work if I force a 'return 0' into the ulpi_check_integrity function. I was wondering if anyone has any suggestions as to where to inspect/debug the fact that the read/write to the OTG PHY scratch register does not match.
