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
|
|
|
