[jekenpwn]

Hi renesas team,

We want to USB2.0 and USB3.0 to share using the USB2.0 external clock.

I tried to follow the BSP document (RENESAS_RCH3M3M3NE3_USB3.0H_UME_v2.01.pdf)
However, the USB3.0 host interface just can using the USB2.0 function, and USB3.0 devices will show below errors:
PLS give me some suggestions.

Hi Jeken,

USB 3.0 on the Salvator-xs is not be enable by default, you need to add USB3.0 node in device tree and re-build kernel, you can refer my changes on kernel configuration looks like to add usb 3.0 firmware and rebuild kernel again:

##Kernel configuration
Device Drivers --->
Generic Driver Options --->
-*- Userspace firmware loading support
(r8a779x_usb3_v3.dlmem) External firmware blobs to build into the kernel binary
(firmware) Firmware blobs root directory

		Device Drivers --->  
			[*] USB support ---->  
				<*> Support for Host-side USB  
				...  
				<*>xHCI HCD (USB 3.0) support  
				-*-Generic xHCI driver for a platform device  
				< >xHCI support for Mediatek MT65xx  
				<*>xHCI support for Renesas R-Car SoCs    

	##USB3.0 clock configuration  
		Device Drivers --->  
			PHY Subsystem --->  
				-*- PHY Core  
				...  
				<*> Renesas R-Car generation 3 USB 2.0 PHY driver  
				<*> Renesas R-Car generation 3 USB 2.0 clock selector PHY driver  
				<*> Renesas R-Car generation 3 USB 3.0 PHY driver  

	##Enable USB Video Class (UVC)  
		Device Drivers --->  
			Multimedia support --->  
				[*] Media USB Adapters  
					[M] USB Video Class (UVC)  
					[*] UVC input events device support (NEW)  

Hope this helps
