USB - HSIC port 2/3 support in uboot on imx6solo/dual

[pavansingpatil]

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.

Hi igor,

Thanks for the reply.

sorry for not mentioning earlier but i have seen and through these patches earlier but as you know its for barebox and we are using uboot and these patches won't be much useful for uboot since similar files are not exist in uboot.

any suggestion on uboot would be helpful. 

Regards,

Pavan
