Re: USB Keyboard Support

Everyone,

I recently got the USB device up and working under DENX Linux 2.4.25 with a
MPC8280.

We are using a Sm501 video chip and also have that working now, I was hoping
to get the USB Keyboard system and running so I could totally run the system
without having to use the serial port as the stdin/stdout anymore.

However, I am having trouble getting any USB keyboard input to be recognized
as the stdin or anything really.

I have verified that the kernel sees the keyboard and associates the correct
HID driver, and keyboard driver with it.  Also I have added the
/dev/input/input0-3 files and have verified that they are receiving garbage
when keys are pressed. i.e. via 'cat input0' and dumping the input to the
console.

Anyone know what else is required in order to setup the USB keyboard as the
input device when using a VGA console?

Thanks,

-Russ

Dear Russ,

We have MPC5200Lite board running DENX Linux 2.4.25 with Fujitsu CoralP video card.
To have have the USB keyboard as system stdin, the only thing I have done is to remove "console" args from kernel command line. I use the following command lines:

1)To have the console output on serial line and screen, and the input on serial line:

root=/dev/nfs rw ip=on console=tty console=ttyS0 init=/sbin/init

2) To have the console input on the USB keyboard and the output on the screen:

root=/dev/nfs rw ip=on init=/sbin/init

I have atached our kernel configuration.

Hope this helps.
