Dear Deval Shah,
I checked my rasberry board. my board is rasberry Pi B+. (It is not RPI2 B+)
I am sorry. I returned to rtems, libbsd version for Pi B+.
Anyway, I guess that both bcm283x_dwc_otg_probe() and
bcm283x_dwc_otg_attach() function should be called.
I don't know how to call bcm283x_dwc_otg_probe() and
bcm283x_dwc_otg_attach().
Please advsie me.
Best Regards,
Thomas Kim.
