Hi All,
firstly Before going to boot from USB key, I tried to make working flash "uImage to OSK5912" using USB.
and after compiling drivers/usb/usbdcore_omap1510.c with adding following macros
to include/configs/omap5912osk.h

#define CONFIG_CMD_USB          1
#define CONFIG_USB_DEVICE      1
#define CONFIG_USB_TTY         1
#define CFG_CONSOLE_IS_IN_ENV 1
#define CONFIG_USBD_MANUFACTURER       "OSK5912"
#define CONFIG_USBD_PRODUCT_NAME       "Osk5912 Bootloader " U_BOOT_VERSION
#define CONFIG_EXTRA_ENV_SETTINGS      "usbtty=cdc_acm\0"

after this, I set "setenv stdout usbtty" and "setenv usbtty cdc_acm" from U-boot serial console.

Now, I am, able to get U-boot console over USB after connecting to Linux Host.

But I am facing following problems,
1) I am getting every typed character twice(i.e. like local echo, but I checked local echo of minicom, it is off. same is happening
using kermit also.)

like following,
------------------------------------------------
Welcome to minicom 2.2

OPTIONS: I18n
Compiled on Mar 9 2007, 07:21:40.
Port /dev/ttyUSB0

                 Press CTRL-A Z for help on special keys

OMAP5912 OSK # OMAP5912 OSK #

OMAP5912 OSK # OMAP5912 OSK #

----------------------------------------------------------------------------

Also, this is not stable and gets disconnected offen. Please, suggest if have any Idea to resolve this problem.

2)also to download uImage to OSK(because loadb uses kermit), I installed Kermit.

Now, if I try to send uImage to OSK5912, it continues for some time, and connection gets lost, and OSK5912 U-boot
Serial console(i.e. over /dev/ttyS0) comes up, with some older flashed u-boot.bin

Not, sure why this is happening. Please, suggest if any Idea.

Thanks and Regards,
Shivdas Gujare

No idea. You will have to RTFM.

Drop this. This would enable the old OHCI support.

You *might* have to implement these in order to enable power, clocks ...

You probably missed some initialization. Carefully check the
documentation of you CPU and implement it in the functions above.

Exactly.
