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.
Best Regards,
Thomas Kim
