BeagleboardXM - No USB keyboard, mouse on Gingerbread

Hi,

    I have the BeagleboardXM RevC and I am having trouble getting USB mouse and keyboard to work. Tried the pre-built images and also built my own using the devkit. A colleague of mine also tried it on a different BeagleboardXM using pre-built and custom built images with the same results. I am connecting the USB keyboard and mouse to the on-board USB host and the board is powered using a 5V/3A power supply.

    Attached is the console output for reference and the patches I applied trying to get the kernel built.

Thanks,

    Hi Aniruddh,

    Please connect external power hub and try again.

    You can check keyboard and mouse events using getevent command.

        $ getevent

    Hi Aniruddh,

    From the boot log you have provided, I understand that you are trying to run 2.6.32 kernel on BeagleBoard XM revision C.

    Some additional patches are required for this version kernel to run on BeagleBoard XMC. I have attached the same. 7183.0001-DVI-color-and-USB-fix.txt

    Our latest DevKit fully supports BeagleBoard XM C on kernel 2.6.37. You can download it from http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_GingerBread_2_3_4_DevKit_2_1/index_FDS.html

    Hi Arun,

           Thanks for your help. Unfortunately that patch failed to apply. Looking at the patch contents I see that there are several functions in it which are missing in my base file from the DevKt. So I guess another intermediate patch might be needed. I found this patch which seems to be much similar to yours but also adds the missing functions. 8446.USBKeyboardPatch-ebe1e26476768b8edde0607433e564ffd4b0e903.patch.txt

    I had tried this patch earlier but it did not work. Please let me know if this patch is ok or it needs any changes.

    Thanks

    Hi,

    Which is the devkit you are trying to use?

    If you take BeagleBoard XM package from http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_GingerBread_2_3_4_DevKit_2_1/index_FDS.html , then it will work without fail on BeagleBoard XM C.

    The sources are also provided in the same page.

    I have provided the patch for 2.6.32 kernel since I thought you were working on rowboat 2.6.32 kernel base. Please try out the latest release on your board.

    Hi Arun,

          That worked. But now I am having problem with video playback. The video plays fine but its size is not correct. I am using the following bootargs

    setenv bootargs 'console=ttyO2,115200n8 androidboot.console=ttyO2 mem=256M omap-dss.def_disp=dvi omapfb.mode=dvi:1600x1024MR-16@60 omapfb.video_mode=1600x1024MR-16@60 omapfb.mode=dvi:1280x720MR-16@60 root=/dev/mmcblk0p2 rw rootfstype=ext3 rootdelay=1 init=/init ip=off omap_vout.vid1_static_vrfb_alloc=y vram=32M omapfb.vram=0:16M mpurate=1000'

    I am trying to play this video http://ia600406.us.archive.org/31/items/ElephantsDream/ed_hd_512kb.mp4. The size of the video is not the same as screen resolution. Please see the image below.

    Also attached here is the complete boot log and output from logcat. 8726.teraterm.log

    Hi Aniruddh,

    Edit hardware/ti/omap3/liboverlay/overlay.cpp file and change LCD_WIDTH and LCD_HEIGHT macros for desired resolution. By doing this video should get played in full screen.

    Let us know if you face any issue.

    Regards,

    Hi Pankaj,

         One last thing. My display dosen't look very crisp despite having set the resolution. Do I need to do something additional? My boot args are as follows

    setenv bootargs 'console=ttyO2,115200n8 androidboot.console=ttyO2 mem=256M omap-dss.def_disp=dvi omapfb.mode=dvi:1600x1024MR-16@60 omapfb.video_mode=1600x1024MR-16@60 omapfb.mode=dvi:1280x720MR-16@60 root=/dev/mmcblk0p2 rw rootfstype=ext3 rootdelay=1 init=/init ip=off omap_vout.vid1_static_vrfb_alloc=y vram=32M omapfb.vram=0:16M mpurate=1000'

    Thanks,

    Aniruddh
