2008-11-05 Thread richard.zhao

Oh, I have made mistake, the project at 
http://focus.ti.com/dsp/docs/dspsplash.tsp?contentId=3100 ,not for DM355. How 
to get the package for

Hi all,

I downloaded the gstreamer sourcecode from 
http://focus.ti.com/dsp/docs/dspsplash.tsp?contentId=3100 and followed the 
instructions by SPRAAQ9.pdf, but the compiling just failed when configure glibc

... ...

checking for growing stack pointer... configure: error: cannot run test program 
while cross compiling
See `config.log' for more details.

How can I solve this problem?
And I also found a post at

The first statement inside if and else is the same. This can be moved out.

Also, I think, there is some portion of the code at the end, in the same 
function (davinci_i2s_hw_params), which requires conditional check as above.

RE: Encodedecode: Failed to open codec engine

2008-11-05 Thread Kamoolkar, Mugdha

I suspect that if you rebuild user-side, you may need to rebuild the 
application also (which includes dsplink.lib) for the change to take effect. 
Another (easier) option is to enable USE_CHNL (make it 1) and rebuild the 
dsplinkk.ko kernel module. That wouldn't need application rebuild.

Also, I forgot to mention that in addition to USE_CHNL becoming 1, 
USE_CHNL_ZCPY_LINK also has to be set to 1. The best way would be to run the 
dsplinkcfg.pl script because that would do all the reconfiguration fully.

Hi Mugdha,

Thanks for your reply and the pointer.
I've checked the dsplink configuration at 
dsplink/packages/dsplink/config/CURRENTCFG.MK (is it the right place?) and it 
seems that CHNL module is ON:

 export USE_CHNL:= 1


The error is launched when TraceUtil_start(ENGINE_NAME) is called from main().
ENGINE_NAME's value is "encodedecode".

Maybe I touched something in build toolchain, because with my current 
environment every demo fails in the same way. However, old backed-up binaries 
work fine.

Is there some place in the demos toolchain, where dsplink configuration could 
be modified and then make demos fail? Does this make sense to you?
Is a goog idea to recompile dsplink introducing more traces?

dsplink and cmem modules appear when I lsmod in the target.

And you're right, my dsplink version is 1.30.08.02.

Thanks and regards,
Jose.

Jose,

The error prints that you got in debug build are from DSPLink. For example, 
look at the first error:
Failure: Status:[0x80008008] File:[0x50c] Line:[216]

Look at the following wiki page for an interpretation of this:
http://tiexpressdsp.com/wiki/index.php?title=Debugging_DSPLink_using_SET_FAILURE_REASON_prints

This tells us that the file was dsplink/gpp/src/api/Linux/drv_api.c
Failure was at line 216.
In DSPLink version 1.30.08 (which is the version you seem to be using), this 
indicates following failure:
#if defined (CHNL_COMPONENT)
if (DSP_SUCCEEDED (status)) {
osStatus = ioctl ((*drvObj)->driverHandle,
  CMD_DRV_GETCHNLMAPTABLE_ADDRESS,
  &cmdArgs) ;

if (osStatus < 0) {
status = DSP_EFAIL ;
SET_FAILURE_REASON ;
}
That means that the ioctl failed. The only reason I can guess that the ioctl 
would fail, is if, for some reason, the DSPLink kernel module dsplinkk.ko was 
built with CHNL module off in the DSPLink configuration. But the user-side 
library of DSPLink was built with CHNL module enabled. In this case, the 
user-side #if defined (CHNL_COMPONENT) would go through, and attempt the ioctl.
But the kernel driver does not understand this command and hence fails.

Is this possible in your build?

Regards,
Mugdha

Error: Failed to create h264 video encoder

2008-11-05 Thread Craig Smith

Hello All, I am using the DM6467 EVM and trying to modify the
encodedecode demo to take a 1080i source (a camera). I works fine in
pass through mode, but when I try to get it to encode/decode, the
encoder creation fails. I have debugged it as far as I could and
traced it down to the call to VIDENC1_control(inside of Venc1_create)
returning a status of -1. But I have no indication of what parameters
it is complaining about. I understand that the encode/decode will not
keep up real-time, but I just want to make sure the encoder is working
for 1080i. BTW, it does work fine for 720p.

I've included some more debug info below. If anyone has an idea of
what I'm missing (or if I can provide more info), please let me know.
Thanks so much.

Best regards,
-Craig

Thanks for your quick answer, Steve.

Yes, I think it is already correctly configured:

/*
*   Engine Configuration  */ var Engine =
xdc.useModule('ti.sdo.ce.Engine');
var demoEngine = Engine.create("encodedecode", [
{name: "h264enc", mod: H264ENC, local: false, groupId: 0},
{name: "h264dec", mod: H264DEC, local: false, groupId: 0},

]);

David,

Fbset should display correct settings of fbdev window configuration.

For LSP1.20, you can set the following as part of your bootargs to set bootup 
output and display mode:
davinci_enc_mngr.ch0_output=LCD davinci_enc_mngr.ch0_mode=640x480

If these are not set, then output is default to be COMPOSITE and mode NTSC 
(720x480), which is why you still see resolution 720x480. 'output=lcd' style of 
bootarg is no longer supported.

Regards,
Owen

I think this is not the problem of no effect. But just a problem of report.
As I check with my system. When set to video=davincifb:output=lcd. resolution 
is set to 640x480.
And as I checked all Xres and Yres. All right, but fbset -i will report 720x480.

RE: nanosleep failing with EINTR during video process calls on DM355

2008-11-05 Thread Grosen, Mark

Srikanth,

The use of a signal (SIGUSR1) by the codecs was removed in the later releases 
of the codecs. This should fix the issues you are seeing and make it easier to 
debug using gdb. You can find how to upgrade at http://davincidsp.com and 
registering your board.

Subject: nanosleep failing with EINTR during video process calls on DM355

Hey all,

I have observed on DM355 that if one thread tries to "sleep" while another 
thread is making video encode/decode process calls the sleep fails.

I see the same behaviour even in the encodedecode demo that came with the 
DVSDK. I used the nanosleep API to sleep for 2s in one thread while the video 
encode/decode was running and the nanosleep failed with an EINTR error 
(immediately). The perror print is (unsurprisingly
:-) ) "Interrupted system call".

Any ideas why this could be happening?

One thing I did notice is that the process calls on 355 seem to be generating 
SIGUSR1 interrupts on DM355. You can see this if you run the encodedecode demo 
usingg gdb. Could it be because of this? If so, any idea how I can prevent this 
interrupt from interrupting the nanosleep?

CCDC and debugging...

2008-11-05 Thread Andrea Gasparini

Hi, 

I've some problems with interfacing a sensor with the CCDC of a DM355 
powered custom board and a mv4.01 kernel.

I'm still not receiving any interrupt, and I'm figuring out why.
So, I'm trying to decode the STADRH and STADRL registers: I noted that if 
v4l call the ccdc driver with an address (let's say: 0x8600 ), it went 
transformed in 0x30 inside STADRH and 0x0 in STADRL...
So, the questions are:

- why 0x30?? when the DDR EMIF offset should be only 0x8000 ?? 
Shouldn't it be 0x600 ? Am i missing some steps?

- after that, how can I see if the CCDC is writing something on memory? 
That could help me in distinguish if the problem is the irq, or the whole 
transfer. ( let's assume that the sensor works well...)
 I tried to read /dev/mem at offsets 0x8600, 0x600, 0x30 but it 
doens't work (it segfaults).

Thanks, bye!

RE: Can we rebuilt dvsdk_1_40_01_32/dm6467_dvsdk_combos_1_17 ?

2008-11-05 Thread Azbell, Brandon

Mike,

Yes, this is something that has been reported and we are working on 
including the ability to rebuilt the codec engine servers with the DVSDK. 
I don't have a timeframe for an updated DVSDK to resolve this though.  A way to 
work through this is to use the Codec Bundles available on the following site 
to get the libraries to rebuild.  These can be found at the TI e-Store 
http://www.ti-estore.com.

Strange problem with Linux git version. lcd crashes ttyS0 console! goto USB problem now

2008-11-05 Thread Pablo Bitton

Hey,

I've got the same Oops as you.
It seems that all you need to do is "modprobe pcf857x" before you
"modprobe musb_hdrc".
By the way, I think it's better to build pcf857x driver as a part of
the kernel image.

Good luck.

Encoder Manager support"
i doubt that, the kernel version i have is not the one that the SPRUEK9 
document talk about, since in the document he talk about folder structure with 
slightly different names such as, in the document he talk about folder with 
name "mv_pro_4.01" but which i find is "mv_pro_4.0"
so it seem i want another kernel, am i right and if so, from where i can get 
this new kernel?

If you follow section 3.3.1 in SPRUEK9, you should see Device Driver -> Video 
For Linux -> "Davinci Encoder Manager support". If you build DM355 or DM6446 
defconfig, it is on by default.

Re: Davinci-linux-open-source Digest, Vol 35, Issue 11

2008-11-05 Thread David Chan

I think this is not the problem of no effect. But just a problem of report.
As I check with my system. When set to video=davincifb:output=lcd.
resolution is set to 640x480.
And as I checked all Xres and Yres. All right, but fbset -i will report
720x480.

What is purpose of targetFrameRate and refFrameRate in dynamic parameter of Video Encoder?

2008-11-05 Thread Deepika Makhija


Hi All,

I am working on DM355 evm board.  As I am new to this environment I had 
few doubts in Video encode demo application.

What is purpose of targetFrameRate and refFrameRate in dynamic parameters?
I guess those are to indicate the codec the frame rate. But what is need 
for two different variables?


Can anyone guide me on this?

Thanks in advance

Regards,
Deepika

unclear high resolution jpg image

2008-11-05 Thread ashish pareek

 Hi ,
I am using Dm355 with mt9t001 image sensor .
My application saves YUV image and encode it using jpegencoder .It works fine 
with 1280x720 resolution and i get a clear jpg image .
But while working with high resolution 1920x1080 , i couldnt get true image 
.Instead i got image consisting of 2 different colour bands .
Could any one tell me the possible cause for that ?

Does any one having any reference code for similar application?

Re: LSP1.2 kernel configuration help request

2008-11-05 Thread Andrea Gasparini

Hi, 

Mohamed AbdElwahed spiffera, alle Wednesday 05 November 2008 circa:

1) no attached stuff seen.
2) drivers/media/video/Kconfig state that:

config DAVINCI_VPBE_ENCODER>
tristate "Davinci VPBE Encoder support"
depends on (DAVINCI_ENC_MNGR) && (FB_DAVINCI || VIDEO_DAVINCI_DISPLAY)

So, perhaps you have to enable FB_DAVINCI or VIDEO_DAVINCI_DISPLAY as well.
Don't really know if mv4.0 is so different from 4.01, it seems strange...
