RE: davinci: DA850: GLCD support
Hi Francis,
Basically, you are trying to rotate image by 90. Can you check you LCD to see
if it supports these kind of rotated timing parameters? If it does not, you
will have to take care of rotating input image in the application.
Thanks,
Brijesh Jadav

Hi,
The LCD i used here as Sharp - 480*272. HEIGHT is 272, Width is 480. Now i can
see the image on GLCD in Landscape mode.
I want to change my LCD orientation in Portriat mode permanently. I modified
timing parameters in linux-xx.xx./drivers/video/da8xx-fb.c
as follow.
/* Sharp LK043T1DG01 */
[1] = {
.name = Sharp_LK043T1DG01,
.width = 272,
.height = 480,
.hfp = 3,
.hbp = 3,
.hsw = 10,
.vfp = 2,
.vbp = 2,
.vsw = 41,
.pxl_clk = 7833600,
.invert_pxl_clk = 0,
},
But i am not able to see my image in Portriat orientation. please any one can
suggest and solve my issues.
Regards,
Francis

RE: davinci: DA850: GLCD support
Hi francis,
This is actually console rotation, Linux console driver takes care of rotating
you console. This does not rotate your normal frame buffer. Actually the
underlying fb driver is totally ignorant of console rotation.
I think there are some boot time parameters, you can use them to rotate your
console. See if below text helps.
4. fbcon=rotate:n
This option changes the orientation angle of the console display. The
value 'n' accepts the following:
0 - normal orientation (0 degree)
1 - clockwise orientation (90 degrees)
2 - upside down orientation (180 degrees)
3 - counterclockwise orientation (270 degrees)
The angle can be changed anytime afterwards by 'echoing' the same
numbers to any one of the 2 attributes found in
/sys/class/graphics/fbcon
rotate - rotate the display of the active console
rotate_all - rotate the display of all consoles
Console rotation will only become available if Console Rotation
Support is compiled in your kernel.
Thanks,
Brijesh Jadav

Hi Brijesh,
Thanks for your mail.
Basically my default GLCD settings are in Landscape(Display 480(W)x272(H)). I
am able to rotate the image in portrait orientation(270) using echo 3
/sys/class/graphics/fbcon/rotate_all command. Once it restart my target again
it goes to default mode. We are developing our own customized Qt application. I
want to viewport size as always in portrait mode.
Any driver changes or something we can modify it in scripts. Please suggest me.
Thanks,

RE: LSP 2.10 Previewer hung on preview task
Hi, Can you check whether H3A is enabled in the Kernel and CCDC output for H3A is enabled? As far as I remember, there was some issue with the H3A and previewer. When H3A is enabled, previewer stops giving interrupts. Can you check whether previewer interrupts are coming properly? You can check it by printing /proc/interrupts file. There should an entry for the previewer in this file and it should be incrementing if interrupts are coming properly. If interrupt is not coming, previewer will wait for the interrupt and will not come out of it Thanks, Brijesh Jadav From: davinci-linux-open-source-boun...@linux.davincidsp.com [mailto:davinci-linux-open-source-boun...@linux.davincidsp.com] On Behalf Of Ondrej Pindroch Sent: Monday, July 06, 2009 7:47 PM To: davinci-linux-open-source Subject: LSP 2.10 Previewer hung on preview task Hi Do someone have tested davinci_previewer from LSP 2.10 on DVEVM DM6446.

RE: VPFE
Hi, I think it does not metter how you register dummy slave driver to the kernel. You can even register it as pure char device. May be it is better not to register it at all and have a plain file with dummy functions with the fixed values.

Instead of changing resizer driver, I would suggest to get the major number

Hi,
Are you sure that resizer takes major number 254? I guess it uses
dynamic number allocation.
I believe you are correct, it uses dynamic number allocation. 254 was the
number
I saw it using when the device file was created by the init scripts. How can
I
find the correct major number? I'm not running the init scripts, so there is
nothing in /proc to check.
Maybe I should have asked: How can I use the resizer without running the init
scripts?
AFAIK, you cannot check device numbers without proc or sysfs. Some
options coming to mind:
1)
Edit resizer driver drivers/char/davinci_resizer.c Change line:
result = alloc_chrdev_region(dev, ZERO, 1, DRIVER_NAME);
to:
dev = MKDEV(254_or_some_number_unique_in_the_system, ZERO);
result = register_chrdev_region(dev, 1, DRIVER_NAME);
Don't forget to create node for the number you choose as major.
2)
Create a file in your filesystem and edit, let's say /home/my_init.sh:
#!/bin/sh
mount /proc
RES=$(cat /proc/devices | awk '/davinci_resizer/ {print $1}')
rm -f /dev/resizer
mknod /dev/resizer c $RES 0
/path/to/your/app/app
Then start this script as init, instead of your application.
3)
You can also edit your inittab. Instead of running init scripts you can
just mount some filesystems and then start your application.
I don't use MV fs and kernel, so I can't try these. But I guess they may
give some ideas.

Caglar

RE: OSD support in DM6467
Hi, It does not have any OSD and attribute window. It has only two Video windows. I don't know which demo you are talking about. Applications like DirectFB only runs on the the FBDEV so they will not run on dm6467. For these kind of applications, you need to write a V4L2 layer, same as the FBDEV layer, to display frames.

RE: DVEVM 6467 no signal on output
Hi, Display type mean pixel format? It's because only one pixel format is supported on dm6467 i.e. YC Planar. So there is no need to change it. If display type is bt656 or bt1120, it will be selected based on the mode selected. dm6467 supports four boot time arguments ch0_output, ch0_mode, ch1_output and ch1_mode. These are used to set the output physical connection and mode on that connection on a channel.

On these you get to set both the mode the output with kernel parameters like.. davinci_enc_mngr.ch0_mode=ntsc davinci_enc_mngr.ch0_output=COMPOSITE Here 'mode' can be things like NTSC, PAL, 640x480, 1080P 'output' can be COMPOSITE, SVIDEO, COMPONENT, LCD... (depending on what hardware you have of course). The defaults are COMPOSITE + NTSC which seemed to be what your kernel was saying on boot up. If you have changed the default by editing code are you actually booting the kernel you changed?

They are harmless - the module has loaded and should still function. I would check your boot arguments - I would have expected a x=component (where x is some module parameter or other) in the boot line or is it the default on the 6467 (I don't have a 6467 board to try here)? Just checking your kernel output and it says 'ch0 default output COMPOSITE, mode NTSC' which backs up this idea.
