[U-Boot-Users] USB Uboot on OSK5912

[Shivdas Gujare]

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

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

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
