Problem with vpss.ko

Hello,

Could you share your boot args please?

Also you should use :

./slaveloader startup VPSS-M3 ti816x_hdvpss_1G.xem3

EZSDK has different M3 firmware and utility to load M3 with PSP.

./slaveloader startup VPSS-M3 ti816x_hdvpss_1G.xem3 is the usage of PSP.

Have you rebuild the vpss.ko ?

Best Regards,

Margarita

Dear Margarita,

My boot arguments given below:

Where I can get the ti816x_hdvpss_1G.xem3 and the slaveloader. Could please shar the same?.

I have rebuilt the vpss.ko also and tried. Result remains same.

Thanks in advance,

Hello,

I assume that yo are trying v4l2 capture correct?

I would recommended you to follow this user guide :

http://processors.wiki.ti.com/index.php/TI81XX_PSP_VIDEO_CAPTURE_Driver_User_Guide

or

ezsdk/docs

DM816x_EZ_Software_Developers_Guide.pdf

How to change from OMX to V4L2 firmware for capture/display

Hi Margarita,

I am trying to test the display device and HDMI (ti81xxfb.ko, ti81xxhdmi.ko). But I couldn't load the module the vpss.ko. I want to know what might be the reason for it. Please let me know solution for the same. As I already posted the error message in my first update.

Thanks in advance,

Regards,

Salih

I have successfully inserted my vpss.ko module after I downloaded the binaries with the version TI81xx-HDVPSS-01.00.01.37 in my target. But my LCD device is not enabling after I given the below commands.

echo 0 > /sys/devices/platform/vpss/graphics0/enabled
echo 1:dvo2 > /sys/devices/platform/vpss/graphics0/nodes
echo 0 > /sys/devices/platform/vpss/display1/enabled
echo 800x480@60 > /sys/devices/platform/vpss/display1/mode
echo 1 > /sys/devices/platform/vpss/display1/enabled
echo 1 > /sys/devices/platform/vpss/graphics0/enabled

Can you please tell me what might be the reason for the same. I am using the external LCD panel in my target.

Thanks in advance.

Regards,

Salih

Hello,

You could try:

/etc/init.d/matrix-gui-e stop
/etc/init.d/pvr-init stop
echo 1:dvo2 > /sys/devices/platform/vpss/graphics0/nodes
echo 0 > /sys/devices/platform/vpss/display1/enabled
echo 33500,800/164/89/10,480/10/23/10,1 > /sys/devices/platform/vpss/display1/timings
echo 1 > /sys/devices/platform/vpss/display1/enabled
fbset -xres 800 -yres 480 -vxres 800 -vyres 480
/etc/init.d/matrix-gui-e start
 /etc/init.d/pvr-init start

Let me know the result.

Best Regards,

Margarita

Hi Margarita,

I have executed the same commands as you given. But still the behavior of the LCD remains same.

Please suggest any solution to solve this issue.

Thanks in advance

Salih

Hello,

What you are meaning "not enable"?

You could check these e2e forum threads they are related with LCD and dm8168.

Hi Margarita,

Thank you for your support. I have solved this LCD issue, since some conflict of GPIOs in our customized platform.

Now I want to test the Video in my LCD. Can you send me the procedure to play the video in my display device.

How can I use the G-streamer in my target?.

Thanks in advance.

Regards,

Salih

Hello,

How can I use the G-streamer in my target?.

You  could start with:

gst-launch filesrc location=/usr/share/ti/data/videos/dm816x_1080p_demo.264 ! 'video/x-h264' ! h264parse access-unit=true ! omx_h264dec ! omx_scaler ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! omx_videosink

This will decode&display the elementary stream dm816x_1080p_demo.264.

Let me know your use case and your questions regarding gstreamer. Please open a new topic about it.

Best Regards,

Margarita

Hi Margarita,

As I have used the above commands in my target. It showing below errors in my target and nothing executing in my display device.

Hello,

As per your first post it seems that you are using ezsdk 5.03 right?

The syslink version in this ezsdk is 2_00_05_85 but errors shows syslink 2.20.02.20. One of the reasons could be syslink verions mismatch. Please move to the latest EZSDK 5.05.02 version.

Also the provided pipeline is working on DM8168 it decode and displays on HDMI the video. Could you provide me more information what changes you have made in the EZSDK?

I would recommended you to check with the default EZSDK first.

Best Regards,

Margarita

Hi Margarita,

Thank you very much for your response. As I already moved to the latest SDK (ti-ezsdk_dm816x-evm_5_05_02_00).

As I downloaded the file (syslink.ko (SysLink version : 2.10.03.20), slaveloader, ti816x_hdvpss.xem3) from the TI website with the VPSS version TI81xx-HDVPSS-01.00.01.37.

I have executed the below commands to load the display related modules:

insmod syslink.ko
./slaveloader startup VPSS-M3 ti816x_hdvpss.xem3
insmod vpss.ko
insmod ti81xxhdmi.ko
insmod ti81xxfb.ko

And also I changed my customization in the Linux source code. And I have used the targetfs provided by EZSDK.

I have executed the simple pipeline in the target as below:

gst-launch playbin uri=file:///home/root/tfr.mp4

Results remains same as I am getting the below run time error messages:

But if you are trying to execute the pipeline with playbin2 you should do:

Stop the graphics plane,

cd usr/share/ti/ti-media-controller-utils

./load-hd-firmware.sh stop

./load-hd-v4l2-firmware.sh start

Hi,

I have tried to load the syslink (syslink_2_20_02_20) and tested. I am getting the below message while loading the vpss.ko module:

VPSS_FVID2: M3 firmware version 0x1000144 is newer,driver may not work properly.

And also while executing pipeline getting the same error messages and not working.\

How to stop the graphics plane in the target?. Please suggest any solution to solve this issue.

What changes you have made?

Are you seeing this with the default EZSDK without any modifications?

Best Regards,

Margarita

Hi,

Yes. I didn't do any changes in the EZSDK (targetfs). I have made changes only in Linux and U-boot source code.

Regards,

Salih

Hello,

Muhammad Salih said:

Then you should rebuild the modules also syslink.ko, vpss.ko etc and to copy them in the in the correct directories in the targetfs.

Best Regards,

Margarita

Hi,

Yes exactly. I have done it and copied the same into it and build the modules. Still the error remains same.

Regards,

Salih

Hello,

Please provide what are the changes which you have made in the kernel , etc. I am able to execute the pipeline without a problem with the default EZSDK 5.05.02.

Best Regards,

Margarita

Hi Margarita,

I am using the processor DM8168 (Rev 2.0 & rev 2.1). I am attaching the patch file with this update.

7870.G12_37_kernel.zip

And also can you send me the procedure of what are commands (modules loaded and others) you executed in the target before executing pipeline and also the pipeline commands.

Thanks in advance

Salih

Hello,

Could you check this pipeline for LCD display:

gst-launch -v filesrc location=location=/usr/share/ti/data/videos/dm816x_
1080p_demo.264 ! 'video/x-h264' ! h264parse access-unit=true ! omx_h264dec ! omx

or you could use v4l2sink device=/dev/videoXX but in case v4l2sink you should execute the load-hd-v4l2-firmware.sh 

Best Regards,
