Display Hanging after Pterm Utility

Dear All,

I am trying to port display driver on QNX for OMAP2430 hardware. I have configured LCD controller, Framebuffer etc. I am
 seeing PTERM windows on the LCD panel and the cursor blinking but thats it. I cannot type any commands in "minicom" 
neither in pterm window(needless to say there is no input driver running). Is Photon expecting an input driver? If it is
, then display driver is depending upon the input driver.
One more thing I read on QNX website that don't use "layer_flushrect()" API. I was seeing this API being called 
continuously, so I commented this API. May I know what does this API do? Is it the same as "blitting"?

I have attached the relevant files for your kind reference.
I would appreciate the help very much.

RE: Display Hanging after Pterm Utility

What version of the OS are you running on?

layer_flushrect() is basically a "hack" for drivers that have virtual
layers, and or an optimization for layers if their GPU can be fine tuned
that way.  It is not necessary, and you should not populate the callout.

Input is not required, but you would need it to type into a pterm.  btw,
you would see this being called continually if you had a blinking
cursor.

I am not sure what you mean by minicom, I assume you mean a terminal
connected to the serial port?
Maybe something is running ready?  Run you terminal at a higher
priority, and check the state of the system.
If it is a serial terminal, you will need to run the serial driver at a
higher priority as well.

Re: RE: Display Hanging after Pterm Utility

Thanks Derek for the reply.
Sorry for not mentioning the OS version. I am running 6.5.

As I mentioned I am not populating the layer_flushrect(), but you are right I could be getting the continuous calls 
because my cursor is blinking.

You are absolutely right about "minicom". I am using a serial terminal to launch the Pterm utility. I am not sure on 
what priority my serial driver is running on. 

I would appreciate Derek if you could look at the attached files and see if there is something wrong in that.

RE: RE: RE: Display Hanging after Pterm Utility

Maybe I misunderstand, but how do you expect to type on the serial
console, if pterm is running in the foreground on the console?  pterm
does not daemonize itself.  I am not even sure that bkgdmgr daemonizes
itself either ... add a & to the end of those lines.

Re: RE: RE: Display Hanging after Pterm Utility

I got the Pterm working. I ran the Pterm in background and I could see the blinking cursor and I can type the commands 
in serial terminal.

I created one simple app to draw a rectangle and I am trying to launch this app from the serial terminal and not the 
Pterm. I have put that application in /src/utils/ folder. The application is there in the image.

I have two question regarding this.

i) Do I need to launch the app from the Pterm?
   If yes, then I will need an input driver.

ii) Can I launch that App from the serial terminal?

I tried doing it but it doesn't draw the rectangle. 
The "Sloginfo" says that gf_draw_begin() failed with gf_errno 1.

Does anybody know why I got this error? I would appreciate the reply.

Note:
I could draw the rectangle by typing following command on pterm "pterm -x10 -y10 -height100 -width100".

One final question. Is there a way to display the QNX home screen on the LCD panel? If yes, then how?

Is this rectangle application a GF or a Photon application?

No, there is no need to run it from pterm.

RE: RE: RE: RE: Display Hanging after Pterm Utility

Ok, you will need to run it on a different layer than Photon, or turn
your application into a Photon/GF hybrid application.  Examples of
hybrid applications can be found at:

RE: RE: RE: RE: RE: Display Hanging after Pterm Utility

Depends how soon you want it to come up ... do you want it immediate, or
once io-display is running, or is it OK to wait until Photon is booted?

Immediate is much more difficult.

If once io-display is running, just run a GF application on a layer that
is behind the layer that Photon will use (if you have more than one
layer).  You can slay it off later.

If after Photon has booted, just run you Photon application before any
other Photon applications.

Re: RE: RE: RE: RE: RE: Display Hanging after Pterm Utility

Thanks Derek.

Primarily we would have liked to do this during startup but now we abandon the idea. Now we want to do it once the 
Photon is up and display driver is running.
I am assuming Photon is running on the main layer, layer=0. I tried with the hybrid app that you shared yesterday but 
could not see any thing on the LCD panel. Looking at the log it seems the GF app is trying to run on the layer=1. 
Pasting excerpt from the log after launching "gf-ph-2d" app.

"img_decode_simple" to draw the image. I do have libimg.so in my image and do see the entries for various image formats 
in img.conf file.

Right now, I do not have "img_decode_simple" utility and I heard it comes with Advanced Graphics. 
How do I get this utility to draw some image on the LCD panel. I would appreciate if you can clarify few of my doubts.

Re: RE: RE: RE: RE: RE: RE: Display Hanging after Pterm Utility

You are right Derek, there is no call to attach with any layer in the gf-ph-2d code.
So, what went wrong. Why I can't see the gf-ph-2d app running?

Do you suspect anything wrong with my settings? Be it display.conf/omap35xx.conf or the build file. I need to mention 
one thing that I added layer=0 entry in the photon part of the display.conf file.

Raj

ok, Photon is running, correct?  Are you running it as root?  By
default, all GF applications must run as root user.

You are right Derek, there is no call to attach with any layer in the
gf-ph-2d code.
So, what went wrong. Why I can't see the gf-ph-2d app running?

Do you suspect anything wrong with my settings? Be it
display.conf/omap35xx.conf or the build file. I need to mention one
thing that I added layer=0 entry in the photon part of the display.conf
file.

Raj

Re: RE: RE: RE: RE: RE: RE: RE: Display Hanging after Pterm Utility

I guess Photon is running alright. All I see is a window with some color on LCD panel along with a command prompt 
terminal just like a serial console. What will be the best way to check if the Photon is running perfectly?
Also, how do I run all the GF apps with root privilage?

Derek, my 2nd question was do I really need "img_decode_simple" utility to draw a bmp/jpg/gif image? If yes then how do 
I get it?

RE: RE: RE: RE: RE: RE: RE: RE: Display Hanging after Pterm Utility

If you can see your pterm, it is running OK.

Yes, GF apps need root priviledge, or you need to set up an access
group, see the documentation for io-display.

The binary for img_decode_simple should be shipped, under /usr/bin, or
do you mean the source?

Re: RE: RE: RE: RE: RE: RE: RE: RE: Display Hanging after Pterm Utility

Thanks. It means Photon is running OK.
I guess I got the idea of running the app in access group.
Is it that we need to put the gf-ph-2d app in the build file under the display driver group where all the other default 
apps like, vsync, pterm, egl-gears are?

I am definitely not talking about the source code of img_decode_simple. I'll just check if we have this under /usr/bin 
folder.

Thanks again Derek. Very much appreciated your help.

Raj

Re: RE: RE: RE: RE: RE: RE: RE: RE: Display Hanging after Pterm Utility

Derek, I found the img_decode_simple app. I followed the procedures mentioned on the QNX website link "working with 
images". I edited the img.conf file to have the entries for JPEG and BMP only. Added the img_decode_simple binary into 
the target as well as added the jpg/bmp files for the drawing. I added this line :

img_decode_simple my.jpg 

into the build script so that it starts the drawing as soon as photon/io-display/io-graphics starts up and running. 
However, I am getting this error 

gf_setup() failed with error 8 which means there is something wrong with the format. 

My display resolution is 240x320 and I am trying with images (125x94/300x282 as I couldn't find the image with exact 
240x320 resolution).

Do you know what is wrong?

regarding the hybrid apps that you shared, I am not able see anything on the LCD panel after running gf-ph-2d & gf-ph-3d
 app.
gf-ph-2d complains about "PdCreateOffscreenContextGF(): No such process" and
gf-ph-3d complains saying "PdCreateOffscreenContextGF(): failed".

But the gf-gl_pg_demo app runs perfectly and I could see the gears moving with some text on the top as well.

Please tell what is wrong I am doing.

Re: RE: RE: RE: RE: RE: RE: RE: RE: RE: RE: Display Hanging after Pterm Utility

Derek, no need for you to spend your time on img_decode_simple issue. Just got that stuff working today. I slayed the 
Photon app and then run "img_decode_simple my.jpg" and I was able to draw the image on the LCD panel.
I just saw another thread inquiring about the FRAME BUFFER concept in QNX display driver.
This one thing is baffling me as well. Although I can do almost everything with my display driver ,i.e, draw images, run
 2D/3D demo apps. The only thing pending is playing a video.

Just wanted to know where are we defining the memory for the frame buffer. Is it the one in build file, the parameters 
we pass to the start up script like omap3530 -L 0x87E00000 0x00020000 ?
I haven't see any reference of frame buffer in the devg code.

The other thing is do we have any test code to test our driver thoroughly?

I would appreciate the reply.

Derek, no need for you to spend your time on img_decode_simple issue.
Just got that stuff working today. I slayed the Photon app and then run
"img_decode_simple my.jpg" and I was able to draw the image on the LCD
panel.
I just saw another thread inquiring about the FRAME BUFFER concept in
QNX display driver.
This one thing is baffling me as well. Although I can do almost
everything with my display driver ,i.e, draw images, run 2D/3D demo
apps. The only thing pending is playing a video.

DL:  Yes, you cannot run img_decode_simple (GF application) on the same
layer that Photon is working, glad you figured it out OK.

Just wanted to know where are we defining the memory for the frame
buffer. Is it the one in build file, the parameters we pass to the start
up script like omap3530 -L 0x87E00000 0x00020000 ?
I haven't see any reference of frame buffer in the devg code.

The other thing is do we have any test code to test our driver
thoroughly?

DL:  Do you have a video decoder on your board?  Does it present to a
physical address?  frame buffer is just a region of memory.

I would appreciate the reply.
