Hi All,

we are using usb hsic port 3 connected to LAN9730 chip and it's initialized and working fine in kernel. but when it comes to uboot i dont see it's getting initialized, tried couple of things

 

we basically need to load Network file system from usb lan in uboot.

 

board.h

#define CONFIG_USB_HOST_ETHER

#define CONFIG_USB_MAX_CONTROLLER_COUNT 4
#define CONFIG_EHCI_HCD_INIT_AFTER_RESET /* For OTG port */
#define CONFIG_MXC_USB_PORTSC (PORT_PTS_UTMI | PORT_PTS_PTW)
#define CONFIG_MXC_USB_FLAGS 0
#define CONFIG_USB_ETHER_SMSC95XX

 

config file

CONFIG_USB=y
CONFIG_DM_USB=y
CONFIG_USB_EHCI_HCD=y
CONFIG_CMD_USB=y /* the 'usb' interactive command */
CONFIG_USB_HOST_ETHER=y /* Enable USB Ethernet adapters */
CONFIG_USB_ETHER_SMSC95XX=y
CONFIG_DM_GPIO=y
CONFIG_DM_REGULATOR_GPIO=y

 

but when i try usb start it just scan usb bus 0 and 1.

any suggestion on how to add hsic support in board initialization and initialize usb hsic port on imx6solo/dual.

 

Thanks in advance.
