Following.

Ok. Is USB boot possible if we make changes to Boot Configuration Select HW?

Boot board from USB stick connected in SMSC LAN9512 EVB's hub port. Now I
have added usb option in u-boot, I can see it with 'help' command. But
device is not there though driver smsc95xx is enabled in u-boot.

I noticed that EVB device is using fsl-echi driver for USB/Ethernet after
boot.
*        From console: *usb 1-1.2: new high speed USB device number 4 using
fsl-echi* *

when I connect USB stick to hub's port.
Should I enable echi-fsl driver to u-boot also?

My u-boot configs for USB command are:
/* USB Configs */
#define CONFIG_CMD_USB
#define CONFIG_CMD_FAT
#define CONFIG_USB_EHCI
#define CONFIG_USB_EHCI_MX6
#define CONFIG_USB_STORAGE
#define CONFIG_USB_HOST_ETHER
#define CONFIG_USB_ETHER_ASIX
#define CONFIG_USB_ETHER_SMSC95XX
#define CONFIG_MXC_USB_PORT 1
#define CONFIG_MXC_USB_PORTSC (PORT_PTS_UTMI | PORT_PTS_PTW)
#define CONFIG_MXC_USB_FLAGS 0

In addition, is this USB option even possible to implement because of dip
switch(SW-6)?
And if it is, in what position switch dip's should be in USB boot?
BTW, Can I override switch by software(BOOT_MODE and GPIO Boot override
pins)?

br,
