hello
I checked with the hardware spec
in that
P1020RDB: having connection like
P1012processor -> PHY -> HUB -> ports
whereas in custom board
P1012processor -> phy -> port(single usb port)
In uboot source code initializing sequence of u-boot
is below:
1.usb_init()
2.usb_scan_devices()
3.usb_new_device(dev)
4.usb_hub_probe(dev, 0)
5.usb_hub_configure(dev)
how can we do this in u-boot source code
