HDMI Testing

Preqs:

  • usb keyboard and mouse to interact with the GUI
  • HDMI monitor
  • install libdrm-tests
sudo apt install libdrm-tests

a) Test with various monitors

Test with different monitors

  • open a terminal in the GUI
  • run the command xrandr
$ xrandr
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
   1920x1080      0.00*
  • run modetest - this will confirm the edid parameters etc.
$ modetest -M tidss

b) Test Hot plug detect

The HDMI framer is at 0x4c on this board. So we can use:

$ cat /proc/interrupts |grep 4c

to test the number of interrupts we get.

plug out and check the count of interrupts and plug in and check the count of interrupts

debian@BeagleBone:~$ cat /proc/interrupts |grep 4c
368:          1          0          0          0      GPIO  36 Edge    -davinci_gpio  2-004c
debian@BeagleBone:~$ echo "plug off"
plug off
debian@BeagleBone:~$ cat /proc/interrupts |grep 4c
368:          2          0          0          0      GPIO  36 Edge    -davinci_gpio  2-004c
debian@BeagleBone:~$ echo "plug back in"
plug back in
debian@BeagleBone:~$ cat /proc/interrupts |grep 4c
368:          3          0          0          0      GPIO  36 Edge    -davinci_gpio  2-004c
  • There should'nt be infinite interrupts in the system
  • The GUI should also come back online after plugging the cable back in.

b) Test HDMI Audio

Pick your fav mp3/wav/whatever file,

sudo apt-get install qmpp
  • Play music, confirm audio time matches the length of music to be played.
  • increase decrease volume on GUI
