Thank to your advice we managed to find a mistake on board, USB was sealed in inversed manner.

 I managed to connect USB flash storage with FAT32 fs, mount it and even display a filce contained on storage.

USB hub connected works good too.

Usb mouse connected works properly in GUI Matrix application, but sometimes cursor in Matrix GUI Application disappears, what can be a reason?

Finally keyboard doesn't works in Matrix GUI Application, and application and sometimes even entire device stucks when we try to print web-address in browser.

Best regards,

Anton

I have found something here: http://e2e.ti.com/support/embedded/linux/f/354/p/111342/395247.aspx#395247. I will make a test with USB mouse on my own 816X/389X EVM to see whether I can reproduce the issue. You can also ask this question in our Linux software forum, I think the question is more appropriate for this forum: http://e2e.ti.com/support/embedded/linux/default.aspx

Pavel,

Regarding keyboard in matrix gui application issue:

Andy Friedl said:

I just added "export QWS_KEYBOARD=USB:/dev/input/event1" to the /etc/init.d/matrix-gui-e (e.g right after the export QWS_MOUSE_PROTO... line) and now I'm able to write/type with my USB keyboard (eg in the browser example ;) ).

It hepls, so it seems to be Qt issue, and in fact keyboard works properly.

Regarding mouse issue, I want to say additionally that in fact mouse work properly, the problem is that mouse cursor disappears when you move it out of screen and then trying to move back. I started new thread about in in Linux software forum. I will duplicate issue solving in this thread as soon as it will be solved.

Best regards,

Anton 

Anton,

Regarding the mouse cursor issue, I made a test with my USB mouse and DM816X/AM389X EVM. I do not observed any issue with the mouse cursor. I move the mouse cursor out of the screen and then I move back on the screen, everything is working properly, the mouse cursor does not disappear. Do you have any console message when the mouse cursor disappear? I hope someone from our software team will provide you with hints soon.

Meanwhile, below is what I have into the console, when I plug my USB mouse, do you have something similar?

No console messages. And in fact mouse moving still seems to be processed correctly, just it's cursor just doesn't displays. I infer it because after cursor disappears, when I'm clicking mouse right button, some right-button event image (refresh) appears on matrix gui application. And it looks like it's image position follows assumed mouse shiftings.

Yes, I have:

Pavel, I suggest my matrix gui version is 1, while actual matrix gui version is 2. What version do u use? 

Best regards,

Anton 

Anton,

I think I also use version 1. When boot up, I have the following label up in the middle: "Matrix Application Launcher p1".

And according to the below wiki, this is indicating version 1:
http://processors.wiki.ti.com/index.php?title=Matrix_Users_Guide&oldid=74107

While for version 2, we should have" "Matrix Application Launcher v2", see http://processors.wiki.ti.com/index.php/Matrix_Users_Guide

My previous test was with the latest EZSDK for DM816x device, which is 5.05.02.00. I will test with 5.04 to see if there will be any difference.

Regards,

Pavel

Yes, I have the same.  Also following wiki you provided:

http://processors.wiki.ti.com/index.php?title=Matrix_Users_Guide&oldid=74107

there is two matrix gui v1 subversions: original and enhanced, I certainly have original version.

Is it possible for me to use enhanced version or second version of matrix gui application? I downloaded matrix v2 sources, installed them, could you provide shell script for running matrix v2 if it not meaningless? Also it seems that I have to install matrix browser, is it possible?

Best regards,

Anton 

Anton,

I tested with EZSDK 5.04. As expected, no difference, the mouse cursor does not disappear. The Matrix version in both EZSDK 5.04 and 5.05 is 1.3 :

{EZSK}/example-applications/matrix-gui-e-1.3

Check the {EZSK}/example-applications/matrix-gui-e-1.3/README file for how to build the Matrix GUI.

The matrix-gui-e auto shell script is located at  {ROOTFS}/etc/init.d/matrix-gui-e

Regards,

Pavel

Hi, Pavel

I've found some differences between your and my case. You run matrix gui by default shell script located in /etc/init.d/, don't you? I tried the same: I've connected full HD display to our board and mouse cursor behavior was absolutely proper, cursor didn't disappear.

But I usually use DVI 1440x900 display with my board, so I run matrix gui manually by following script, provided by Margarita Gashova in  thread

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/p/255046/916293.aspx#916293

and in this case we have mouse cursor behavior when it disappears.

 
#!/bin/sh
/etc/init.d/matrix-gui-e stop
/etc/init.d/pvr-init stop
echo 0 > /sys/devices/platform/vpss/display0/enabled
echo 106500,1440/80/232/152,900/3/25/6,1 > /sys/devices/platform/vpss/display0/timings
echo 1 > /sys/devices/platform/vpss/display0/enabled
fbset -xres 1440 -yres 900 -vxres 1440 -vyres 900
/etc/init.d/matrix-gui-e start
/etc/init.d/pvr-init start
cat /sys/devices/platform/vpss/display0/mode

Best regards,

Anton 

Anton,

Yes, following that script, my mouse cursor also disappears.

Pavel

Is there any workaround?

Best regards,

Anton,

I am not aware for any workaround. I will check with the SDK team and let you know if they know something about this.

Best regards,

Pavel

For using the Mouse with QT: 

You should be able to use one of the following instead of specifying touchscreen

export QWS_MOUSE_PROTO=Auto

export QWS_MOUSE_PROTO=Auto:/dev/input/mice
