Dear Deval Shah, I found something.
At this time, I am analyzing libbsd subsystem call procedure. I added additional information on verbose log file for referencing kernel.h (in rtems-libbsd/freebsd/sys/sys) and symbol file which is generated by arm-rtems4.12-nm. I attached this log file(libbsd-verbose-log.txt). As you see in this log file, my surmmary is below; 1) subsystem 310000 is SI_SUB_DRIVERS. also, I checked that dwcotg_nexus_mod, usbus_ehci_mod, umass_uhub_mod, uhub_uhub_mod, uhub_usbus_mod are registered by _bsd_module_register_init(). - I think that it is okay. 2) subsystem 3800000 is SI_SUB_CONFIGURE. I checked nexus_probe() in rtems-kernel-nexus.c is called in this phase. but, device_add_child() is not called in below step of nexus_probe(). SET_FOREACH(nd, nexus) { device_add_child(dev, nd->name, nd->unit); } Finally, I am guessing that device_add_child() for DWCOTG should be called. At this time, I don't know why device_add_child() for DWCOTG controller is not called. Please advise me.
