LCD display

Statistics doenst show any frame drop.Where are you seeing the frame drop in the scaler ? The  Recv fps of channel 1 is only 15.Share the performance log of all the links and mention the expected fps you expect .

Hi Badri,

Sorry  for the late reply.

Yes, I was getting the output on HDMI instead of LCD. when two port is HDMI and LCD is avilable the output buffer even though I have configured for LCD display it was getting frame in HDMI display.

So my linkChain (dataflow) flow there no mistake. I think the display device configuration is wrong.

1. please correct me the display configuration for LCD.

2. In previous post, i have mentioned the frame drop, i was mentioned frame drop based on scalar1 Statistics

 [m3vpss ]  CH  | In Recv In Reject In Process Out Skip Out User Out Latency
 [m3vpss ]  Num | FPS     FPS       FPS        FPS    FPS   Skip FPS Min / Max
 [m3vpss ]  ---------------------------------------------------------------------
 [m3vpss ]    0 |      30         0         30  30        0        0  30  37
 [m3vpss ]    1 |      15         0         15  15        0        0   3   6
 [m3vpss ]    2 |      30         0         30  30        0        0  30  37

if take example channel no 1

CH Num is 1.

In Recv FPS is  15

In Reject FPS is 0

In Process FPS is 15

Out Skip FPS is  15 -----> based on this (skip FPS is 15) I have told frame drop is happening.

pls tell me what is this Out Skip FPS? and tell me the configuration of LCD display?

Regards,

Kolanchi.

Hi TI Experts

I am using ipnc rdk v3.5.  on dm385 board.

with this I am able to display camera captured  freames on HDMI , but when I am trying to display on LCD, nothing is comming on LCD.

I did following changes in use case:

1.

 gVdisModuleContext.displayId[VDIS_DEV_DVO2] = SYSTEM_LINK_ID_DISPLAY_1 ; 

 displayPrm.displayRes = gVdisModuleContext.vdisConfig.deviceParams[VDIS_DEV_DVO2].resolution;

System_linkCreate(gVdisModuleContext.displayId[VDIS_DEV_DVO2], &displayPrm, /*LCD*/
sizeof(displayPrm));

2.  Also I did

d /opt/ipnc/kermod

insmod ti81xxfb.ko vram=0:1M,1:2M,2:1M

echo 0 > /sys/devices/platform/vpss/graphics0/enabled
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 triplediscrete,rgb888 > /sys/devices/platform/vpss/display1/output
echo 1 > /sys/devices/platform/vpss/display1/enabled
fbset -fb /dev/fb1 -xres 800 -yres 480 -vxres 800 -vyres 480

Please give your suggestions:

Rajesh Singh 

Hi Rajesh,

Can you first try to bring up your lcd connected to DVO2? After loading modules, can you run below commands and see if your lcd in coming up with the background color.?

echo 0 > /sys/devices/platform/vpss/graphics0/enabled
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 triplediscrete,rgb888 > /sys/devices/platform/vpss/display1/output
echo 1 > /sys/devices/platform/vpss/display1/enabled

Rgds,

Brijesh

Hi Brijesh ,

Thanks for reply.

I did , as you had suggested and got following output:

1. echo 0 > /sys/devices/platform/vpss/graphics0/enabled

output->   VPSS_GRPX : please open fb0 node first.

2.  echo 0 > /sys/devices/platform/vpss/display1/enabled

output-> No error (LCD become brightening)

3. echo 33500,800/164/89/10,480/10/23/10,1 > /sys/devices/platform/vpss/display1/timings

output-> No error

4. echo triplediscrete,rgb888 > /sys/devices/platform/vpss/display1/output

output-> No error

5. echo 1 > /sys/devices/platform/vpss/display1/enabled

output -> No error (LCD become blank)

Kindly suggest where I could be the problem.

Regards :

Rajesh Singh

Hi Rajesh,

After the last step, can set bit15 at the offset 0x4810a000 and see if you are getting correct color bar on LCD?

Rgds,

Brijesh

Hi Brijesh,

Thanks a lot for your support. 

yes I am getting color bar on LCD after setting bit15 at the offset 0x4810a000.

But when I am trying to display mipi camera  captured contents on LCD, noting is comming. However I am able to display the mipi camera captured contents on HDMI. 

Kindly suggest me, 

regards:

Rajesh Singh

Hi Rajesh,

Since the color bar output is correct, VENC settings and LCD is settings are correct, now you need to make sure that input pipe line settings are correct. Is your captured frame size same as LCD frame size? I am asking this question because it works fine on HDMI.

What do you see on LCD when you try to display image?

Rgds,

Brijesh

Hi Brijesh,

Thanks for reply

1.

When I am displaying on HDMI, I am setting resolution as 1080p ,

while I am displaying on LCD, I am setting resolution as 800X480.

2.

I see black LCD screen, when I am trying to display on LCD.

Regards:

Rajesh Singh

Hi Rajesh,

Is your VENC started? Can you enable color bar after you see blank screen?

Are you starting your input display path after starting venc or capture? Is the input display path connected to the DVO2 VENC? Is your capture input connected to the right display id in the chain?

Could you check above?

Rgds,

Brijesh

Hi Brijesh,

Thanks for quick reply once again.

I will  recheck all the points, what you have suggested, and share with you. 

regards:

Rajesh Singh

Hi Brijesh

Following are the output which I observed for your suggested steps:

1.  I  am able to display LCD patterns, after the screen is getting black.

2. I  have changed following the following files in IPNC RDK 3.5  for TI_8107_BUILD.

     Red color shows what I have added.

Hi Brijesh,

Thanks for your valuable suggestions. Now LCD display is working. but one issue. Display seems to have some noise or someting.

I am sharing one image, please have a look and suggest me some possible causes for this.

.  

Regards:

Rajesh Singh

Hi Rajesh,

Again check the internal color bar, if it is correct, venc is providing correct data. These artifacts are coming from somewhere in your pipeline.

Regards,

Brijesh

Hi Brijesh,

Thanks for reply.

I tested the internal color bar, and it is OK. I am still trying to figure out the cause.

Hi Brijesh,

If same buffers I am displaying on HDMI, there is no noise/line but while displaying it on LCD, image is not proper. 

Kindly give some suggestions.

Hello,

I hope someone can please give me a hint on the following.

I am using 240x320 LCD.

I have found timing parameters which seems to give a stable image, but each time it shows the image on different start line in the screen, and the rest of screen is blank.

when I did:

dd if=/dev/zero of=/dev/fb0

It seems to solve the graphic issue and the image is displayed on full screen starting with line 0 of the LCD screen.

BUt then on starting dvrrdk video application, I see the video each time starting on different line.

Is it a timing issue ? Or should I clean any video buffer to make it work ?

Regards,

Ran

I think, if display link is properly initialize by the application, then there should not 

be any problem.

Hi Rajesh,

Thanks,

So the fact that each time the picture is presented in other part of the screen indicated a timing parameter problem (even though the image is stable), Right ?

Ran

Dear Ran,

in File:
mcfw/demos/mcfw_api_demos/multich_usecase/ti_mcfw_ipnc_main.c
Function:
Void App_loadDemo(Void)

are u doing something like this ?
system("./bin/mem_rdwr.out --wr 0x46c00524 2");
/* FOR LCD*/
OSA_printf("IPNC_DSS_ON: loading fb module for LCD\n") ;
system("insmod ./kermod/ti81xxfb.ko vram=0:2M,1:2M,2:2M") ;
system("echo 0 > /sys/devices/platform/vpss/graphics0/enabled") ;
system("echo 0 > /sys/devices/platform/vpss/display1/enabled") ;
system("echo 33500,800/164/89/10,480/10/23/10,1 > /sys/devices/platform/vpss/display1/timings") ;
system("echo triplediscrete,rgb888 > /sys/devices/platform/vpss/display1/output") ;
system("echo 1 > /sys/devices/platform/vpss/display1/enabled") ;

Replace green line with yours LCD configration.

Thanks,
