Hi Experts,

I had enabled the mouse driver access by changing the configuration file /etc/init.d/matrix-gui-2.0

the following line:

export QWS_MOUSE_PROTO=Tslib:/dev/input/touchscreen0

export QWS_MOUSE_PROTO=Auto:/dev/input/mice

Similarly I tried to enable keyboard driver by appending the line export QWS_MOUSE_PROTO=Auto:/dev/input/by-id/usb-xxx_USB_Keyboard-event-xxxx below it.

Still the keyboard is not detected and not working. Board used is AM335x EVM.

Hi Lyf,

I am not expert, but let me try to help you with debugging,
can you check if configuration "INPUT_EVDEV" is enabled or not ,
I think that is required to be enabled,
Even after enabling INPUT_EVDEV we need need some configuration in the /etc . Google it around, i will paste link if i get it.

Thank you,

Regards,
Ankur

Hi Lyf,

As Ankur suggested,

Please ensure that you enabled the USB INPUT KEYBOARD support in linux kernel.

Also confirm that you are getting EVENTS from keyboard.

Try "evtest" command to confirm.

Hi Lyf,

Glad that it worked,
So was it only INPUT_EVDEV configuration issue ? Or
You had to modify something else also ?

Thank you,

Hi Ankur,

Keyboard configuration has been enabled by default.

When the matrix GUI is loaded for the Linux SDK v7.0 I am unable to navigate using keyboard.

But when I opened the browser and tried to type the URL in the text box then the keys worked out.

Lyf
