Hi Akash, Jagan,
Looks like USB is not functional in u-boot on Rockpro64. u-boot is from git, commit 680023c5fab6b1777c0c6f2e76e5d2effb7903a0.
I'm using u-boot SPL and mainline ATF (19adcb415c313d656324d54e7608cdc7d7a5c414 is ATF commit)
'usb start' doesn't detect anything but hubs and looks like there's no power on USB ports:
=> usb start starting USB... Bus usb@fe380000: USB EHCI 1.00 Bus usb@fe3c0000: USB EHCI 1.00 Bus dwc3: Register 2000140 NbrPorts 2 Starting the controller USB XHCI 1.10 Bus dwc3: Register 2000140 NbrPorts 2 Starting the controller USB XHCI 1.10 scanning bus usb@fe380000 for devices... 1 USB Device(s) found scanning bus usb@fe3c0000 for devices... 1 USB Device(s) found scanning bus dwc3 for devices... 1 USB Device(s) found scanning bus dwc3 for devices... 1 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found
=> usb tree USB device tree: 1 Hub (480 Mb/s, 0mA) u-boot EHCI Host Controller

1 Hub (5 Gb/s, 0mA) U-Boot XHCI Host Controller
1 Hub (5 Gb/s, 0mA) U-Boot XHCI Host Controller
Regulators were probed correctly according to 'dm tree':
regulator 14 [ + ] fixed regulator |-- vcc12v-dcin regulator 15 [ + ] fixed regulator |-- vcc1v8-s3 regulator 16 [ + ] fixed regulator |-- vcc3v3-pcie-regulator regulator 17 [ + ] fixed regulator |-- vcc3v3-sys regulator 18 [ + ] fixed regulator |-- vcc5v0-host-regulator regulator 19 [ + ] fixed regulator |-- vcc5v0-typec-regulator regulator 20 [ + ] fixed regulator |-- vcc5v0-sys regulator 21 [ + ] fixed regulator |-- vcc5v0-usb regulator 22 [ + ] pwm_regulator `-- vdd-log
Any ideas what can be wrong? Have it worked before?
I remember my last checking, give me sometime will check it on master and update you.
Looks like gpio clock is not enabled anywhere in u-boot for rk3399, so gpios just don't work.
rk3399 clock driver is very rudimentary and doesn't touch clock gates at all.
Can anyone explain how it's supposed to work?
