Hi Marek,

Thanks for your reply. I have added the CC to "*u*-*boot*@ lists.denx.de".

Dear Atul Kumar,

Firstly, I'm slightly unhappy how you're deliberately ignoring anything I tell you, especially about CCing the mailing list :-(

Hi Marek,

I have tried to add some code here to enable usbkbd that is below.

-if (strcmp(stdinname, DEVNAME)) -- > replaced with below code

+ if (strcmp(stdinname, DEVNAME) == 0) + { + // Can't use this, so set the stdin to usbkbd instead + setenv("stdin", "usbkbd"); + }

Where is this code, can you generate a proper patch? I can't locate it. Also, why not use simple "setenv stdout usbkbd"?

Here i have just shown removed line of code and added line of code but still under testing. the command "setenv stdout usbkbd" does not give any effect. tried in below sequence and other sequence too.

After stdio register

before strcmp

stdin name- serial

before over write

before console assign

before error test

scan end

setenv stderr usbkbd

OMAP3 beagleboard.org #

setenv stdout usbkbd

OMAP3 beagleboard.org #

setenv stdin usbkbd

As the "setenv stdin usbkbd" is done i am unable to type any thing either from usb keyboard connected to board or Host pc. Even keyboard LEDs are not glowing.

Can you suggest how i should procede.

Dear Marek,

Thanks for your attention.. After doing "coninfo", i get below msg..

All right, maybe you should fix your method of pasting u-boot output, you have every second line blank and a few linebreaks here and there, randomly. It'd be cool to fix it, it'd make it much easier to read. Can you do something about it please?

After doing this my terminal does not prints any logs but i am able to type on console..

You mean with the keyboard? Because "setenv stdin usbkbd" tells the system to read input from the USB keyboard.

Here, I am not able to give input to terminal.. No keyboard lights are glowing.. unable to get back to console to type any thing from keyboard. there is nothing in console "overwrite_console()" function .. do we need to apply any patch here.. please suggest..

Once when i reboot the board again the logs starts coming up..

Ah ... so you got no console output. Try typing on the usb keyboard. If you change stdin to usbkbd, you'd only be able to type with the USB keyboard, it won't pick input from the UART/serial port or whatever other source you use.

I see on "*stdin name- *serial** " .. if instead of serial "*usbkbd*" is there it will be able to register the kbd..

Unable to change "stdin name- serial".. to "stdin name- usbkbd" any other method.. suggest..

I tried this another way but do not find any change in pri ..

Pri? [...]

btw it's a good practice in the mailing list to not top-post (aka reply under the email you're replying to). But if you comment on stuff, you can do it in the middle of the email (just like I did with this one) to better identify what you're replying to.

this is "pr- print environment variables/settings " or pri or print.

Thanks & Regards Atul Kumar

Dear Atul Kumar,

Dear Marek,

I am tring to bring up USB Keyboard on u-boot with "Beagle_board

xM ver B".. found number of post,but the stack is already updated one.. I am able to find the info of the connected device but some how keyboard does not works.. can you suggest/guide me were i am making mistake or where I need to do some device specific changes..

Please always CC the U-Boot mailing list (CCed).

Did you try running "coninfo" after the "usb reset"/"usb start"? What does it output, do you see "usbkbd" there? Wild guess would be to run "setenv stdin usbkbd" or something after you do "usb reset".
