Other Parts Discussed in Thread: TVP7002, TLC59108

Hi,
I refer the technical user guide "TI81XX Video Capture Driver User Guide.pdf" and "TI81XX VPSS Video Driver User Guide", and others questions in TI E2E Community.
So i follow the steps of the documents,and execute saLoopBack then get error message "VPSS_DCTRL: failed to get venc info", i don't know where is wrong? please help me.

//====================================
root@dm814x-evm:/media/sda1/bin# ./saLoopBack

Hello,

Could you try:

root@dm814x-evm:~# /etc/init.d/matrix-gui-e stop
Stopping Matrix GUI application.
root@dm814x-evm:~# /etc/init.d/pvr-init stop
Stopping PVR
root@dm814x-evm:~# cd /usr/share/ti/ti-media-controller-utils/
root@dm814x-evm:/usr/share/ti/ti-media-controller-utils# ./load-hd-firmware.sh stop

root@dm814x-evm:/usr/share/ti/ti-media-controller-utils# ./load-hd-v4l2-firmware
.sh start

root@dm814x-evm:./saLoopBack

Also could you post your bootargs.

Let me know the result.

Best Regards,

Margarita

Hi,

1. My software release version is ti-ezsdk-dm814x-evm_5_05_02_00, and psp version is linux-2.6.37-psp04.04.00.01.
2. I try to follow your suggest steps, then get error message "Setting DV Preset failed".

root@dm814x-evm:/media/sda1/bin# ./saLoopBack
Driver Name: ti81xxvin
Driver bus info: TI81xx Platform
Driver is capable of doing capture
saLoopBack:
Mode set is 0
Setting DV Preset failed

I find this error happen in here isn't a valid video signal to the TVP7002 ADC, is right?
and i had check the connection between media player and DM8148, like this :
media player -> dm8148

(connection is included component RCA jacks, which are Y(green,J9), Pb(blue,J8), Pr(red,J10) )

3. I list these bootargs, but not sure that shell command is correct, please check.

root@dm814x-evm:/media/sda1/bin# cat /proc/cmdline
console=ttyO0,115200n8 rootwait root=/dev/mmcblk0p2 rw mem=364M@0x80000000 mem=320M@0x9FC00000 vmalloc=500M notifyk.vpssm3_sva=0xBF900000 ip=off noinitrd

Hello,

Please check IO expansion board is connected properly. And also make sure that Y, Pb and Pr of component in are connected in respective pins. Because setting/querying of DV preset fails means that it is not able to detect the input resolution.

Could you provide me details about your video source resolution etc.?

This is correct.

Hi,
1. The error Message "Setting DV Preset failed" is resolved, the checking steps are follow like these:
- check hardware connection is ok, and Y, Pb and Pr of component in are connected in respective pins.
- modify media player output resolution to 1080p 60Hz.

2 After execute ./saLoopBack, result the other error messages, and i find these error because in default mode LCD is set for 800X480 resolution, so need to modify it, right? and i also need to your confirmation that this example default display on LCD.

VPSS_GRPX : (0)- region(1920x1080) out of frame(800x480).
Error writing variable information.
: Invalid argument
Error in setting up of Buffers

Then i execute follow shell commands, then error is gone.

echo 0 > /sys/devices/platform/vpss/display1/enabled
echo 1080p-60 > /sys/devices/platform/vpss/display1/mode
echo 1 > /sys/devices/platform/vpss/display1/enabled

3. I reset dm8148 kit and do the steps again, but screen no video display, and instead to show half blanking and half brightness on LCD.
Can you give me some advice?

Hi,

I resolve the display problem. After connect HDMI, the video capture and display is OK, now i can develop my algorithm.

By the way if i need DSP side to run image process algorithm, which things are i need to know? thank you your help.
