Hi all,

I have a sabre automotive i.mx6q board. I installed yocto linux into it.

How can I use keyboard/mouse with it ? When I try to logitech M235 wireless mouse the board can't detect it.

Also which usb port I can use for Keyboard/Mouse ?

Thank you from now.

Is this file avaliable before -make all command in buildroot or it is already in OS after install?

Atm there isn't such a directory in OS.  We are using yocto/open embedded atm. And I  have the finalized image only. My file directory in board looks like this:

bin    lost+found  proc  tmp

boot  home  media       run   unit_tests

dev   mnt      sbin  usr

etc   lib  opt      sys   var

I tried both with mouse and keyboard but it wasn't with the otg to usb 2.0 cable it was with the connector that i posted above.

When i measure the output of otg, is is between 0.2 - 03 mV

In your kernel directory,go to arch/arm/boot/dts . In this location you will get all the device tree related files. Search for imx6qdl-sabreauto.dtsi.

Also have you tried connecting mouse? Is the board able to give power to it?

Hi

You can use the OTG port as shown in the figure.You need to use OTG to USB 2.0 cable to connect your mouse/keyboard
