Re: 8-bit planar support for Resizer
HI! Does that mean, if I am trying to pass say a color separated R or G or B frame, the driver wont be able to process that? As of now I tried doing that, by setting params.pix_fmt= RSZ_PIX_FMT_PLANAR; params.inptyp = RSZ_INTYPE_PLANAR_8BIT; The IOCTL RSZ_S_PARAM fails. I wish to scale up / down a RGB image(using DM6443 resizer) after doing a color separation. Could you please guide me towards a way to achieve that? regards -Nitin - Original Message From: Jadav, Brijesh R brijes...@ti.com To: Vladimir Pantelic p...@nt.tu-darmstadt.de; davinci-linux-open-source@linux.davincidsp.com davinci-linux-open-source@linux.davincidsp.com Cc: davinci-linux-open-source@linux.davincidsp.com davinci-linux-open-source@linux.davincidsp.com Sent: Friday, July 31, 2009 17:50:42 Subject: RE: 8-bit planar support for Resizer Hi, Driver supports planar Resizer but no in the RGB format.

i2c controller timed out\n not able to recover
HI! I have a DM6443 based board and a chip similar to the MSP430 on the development board communicating over i2c. I am getting the error controller timed out\n, while trying to send some command over i2c and reading some data over it. Can some one please help me understand what can be the cause of such timeout? Also a reinitialization which is triggered after such an error doesn't seem to be happening properly. After this error I keep getting the errors timeout waiting for bus ready\n from the function i2c_davinci_xfer() if any data transfer is attempted. Can somebody help me understanding why is it so? regards -Nitin New Email names for you! Get the Email name you#39;ve always wanted on the new @ymail and @rocketmail.

Subject: [PATCH] Reset i2c bus to come out of time out conditions
Get out of i2c time out condition by resetting
the i2c bus. The kernel must be robust enough to
gracefully recover from i2c bus failure without having
to reset the machine. This is done by first NACKing the slave
and then resetting the i2c bus after a certain timeout.
Signed-off-by: Philby John
I tried this on DM6443 based board with 2.6.18 kernel. The result I am posting
below. It gives controller time out again and again.

DM6443 Cursor Window practical use case
Hi, From the VPBE user's guide I understand that the Cursor window can display only a rectangular cursor which is transparent within. I cannot display a Bitmap cursor. Is this understanding of mine correct? Can some one explain me what can be a practical use case for the rectangular cursor being displayed in in the Cursor window? I read the example in VPBE user's guide, still in that case also whats the practical use case for a Bitmap cursor displayed on OSD and surrounded with rectangular cursor boundary?

Well you need to browse v4l plugin and patch accordingly. Check my wiki page on how i got my webcam working http://wiki.davincidsp.com/index.php?title=USB_Webcam on DM6446. This will give you some starting point then patch v4l source (if needed). 2) Not sure why you are using UI on vid window. You should be using fb0 for UI, which support RGB565 or RGB888. You can control the attribute of video and graphics window (like transperancy etc) with fb1. Check the DVSDK demo source, which uses both graphics and video windows and controls the transparency via fb1. If there are some imgaes in the GUI, they would not come properly on OSD windows, since it can at the most take RGB565 (dm6443). The same images would come very nice, when rendered in RGB88 mode on VIDWIN0. Do you have any comments or suggessions in this regard. regards -Nitin Thanks -Brijesh Singh From: Nitin Mahajan [nitin...@yahoo.com] Sent: Saturday, February 28, 2009 2:58 AM To: davinci-linux-open-source@linux.davincidsp.com; Singh, Brijesh Subject: RE: DMAI Based GStreamer Audio Video Synchronisation?

Decoder element normally gets the buffer from demuxer then decodes it and adds timestamp and push to display sink. You will see AV sync from decoder only when the decoder thread is not able to process fast enough to keep-up with demuxer. I would suggest you to enable displayBuffer=TRUE property in decoder elements which will print you the read/write pointer location in circular buffer and will give u some clue. In addition to that, I would suggest modifying the number of maximum buffer queued in queue element after the demuxer. See decode_qt.sh for sample examples. 2) I think video encoder is almost 70% done, during development I tried testing all dvsdk's but will wait for validating result before concluding completed. You can find pretty much the same wording on omapzoom webstie, where the encoder is shown as untested. Now coming back to your problem. * You are trying to capture - encode - decode - display. By default this mode of operation will not work because you can not load two combo's at the same time. By default encoder uses encodeCombo and decoder uses decodeCombo. To solve this problem you need to use loopbackCombo which has both video encoder and decoder. To use loopback combo you need to modify gstreamer codec cfg file. Look at the plug-in source code. * But if I look at your log then you are hitting v4l2src issue. There was some driver bugs (or limitation) and I have patched v4l2src with those workaround. Looks like you are using sensor not the composite (or component) input. We are testing gst with normal EVM bundle which has composite input. If you are using sensor then u may need to modify v4l2src element to work with your sensor driver. Before jumping on v4l2src element, I would suggest using videotestsrc element for testing video encoder. See encode_elementry.sh script. E.g run ./encode_elementry.sh -l -v -o sample.264 This works for us for videotestsrc, but not of a USB video cam. I have one more query. I am displaying the application UI on VIDWIN0 and want to display the video frames on VINWIN1. I want to keep the VINWIN1 disabled/not visible in the beginning, visible with size same as video size during playback and disabled again after playback. What would be the cleanest way to do it when I am using DMAI, in gstreamer plugins.

starting DSP server './decodeCombo.x64P' FAILED

However when I play these media files through gstreamer or TI demo applications on NFS or ext2, ext3 file systems, they play properly. The path of ./decodeCombo.x64P remained same in rootfs, in both the cases, that is on YAFFS2 and NFS. Is there a problem with the DSP server, when it is present in NAND flash file system YAFFS2?

I also saw in the demo application display.c file that the function Rszcopy_execute() is used to copy the frame to framebuffer. I would like to clearly understand that how the VPBE can make use of DMA functionality? Is it the resizer which would take care of this ? Does the resizer internally uses one of the EDMA channels?

I guess this is either a cut'n'paste issue, or perhaps the terminal emulator is not wrapping long lines. Also you cannot put u-boot variables into the bootargs variable, they do not get expanded and the kernel will not know how to handle $(nfsroot) and $(rootpath).

Hi,
You need to escape the $ and ; chars to prevent uboot from expanding the
variable (the $) or attempting to run setboot (the ;). You want the resulting
uboot variable to contain the ${macaddr} unexpanded and the ';' seperating
the
'serenv' and 'run' commands.
IIRC you escape them with backslash (\).
Thanks for your valuable inputs. These two scenarios worked for me, and every
variable was expanded

nothing in memory you get the bad magic number.
If you set the bootcmd to nboot 8070 0 a, I think it should at least
try
to boot.
You then need to sort out the bootargs, as previously posted 'nfsroot=10.65M'
is
not right, it should be an IP address path to the NFS root filesystem on
your
server.
I guess this is either a cut'n'paste issue, or perhaps the terminal emulator
is
not wrapping long lines.
Also you cannot put u-boot variables into the bootargs variable, they do not
get
expanded and the kernel will not know how to handle
$(nfsroot) and $(rootpath). There is a 'trick' to do this that has been used
on
the DM6446.
bootcmd=setenv setboot setenv
bootargs $(bootargs) video=dm64xxfb:output=$(videostd):format=component
davinci-vpfe.device_type=1;run setboot;bootm 0x220
All this did was allow the $(videostd) variable to be picked up at boot time
-
the 'run setboot' was the trick that caused bootargs to be reset with the
expanded variables.
I was going through this valuable trick , and was interested in getting the
ethaddr env variable expanded so that I can get the MAC address in the driver.
I tried doing this after looking at the above example, just to check if the
ethaddr gets expanded
1. set bootcmd setenv setboot setenv bootargs console=ttyS0,115200n8 ro
noinitrd
rw ip=dhcp eth=$(ethaddr) mem=100M;run setboot ## Error: setboot not defined
Can you please tell me, what went wrong here or what would be the correct way
to
achieve this?

RBL, UBL , PSP Boot loader
Hello ! Can some one please explain whether the TI UBL and PSP Bootloader are same? IF PSP Bootloader is not the UBL then where does it reside? Whether the RBL and UBL already programmed in the DaVinci chip? regards -Nitin New Email addresses available on Yahoo! Get the Email name you#39;ve always wanted on the new @ymail and @rocketmail.

RBL - Rom bootloader - embedded in the chip 2. UBL - User boot loader - NOT in the chip - RBL boots UBL (except for NOR and UART boot modes) which boots a secondary bootloader. There are size constraints on what RBL can boot and since most secondary bootloaders do not fit in the size UBL is required - provided by PSP 3. UBoot - secondary bootloader that PSP provides - typically used to boot linux kernel. When someone says PSP Bootloader it could mean either UBL and UBoot and both are NOT in the chip - they are on the external NOR/NAND memory. I assume you have seen the app note Booting DaVinci EVM from NAND Flash which explains the procedure of using UBL/uBoot: http://focus.ti.com/lit/an/spraaa0/spraaa0.pdf TI UBL Version: 1.12, Flash type: NAND Booting PSP Boot Loader PSPBootMode = NAND Starting NAND Copy... Initializing NAND flash... Valid MagicNum found. NAND Boot success. DONE U-Boot 1.3.1 (Jun 12 2008 - 12:21:54) So the above set of messages while booting, indicate that 1. A TI UBL version 1.12 was booted by the RBL, and the UBL was loaded from NAND? 2. Booting PSP Boot Loader PSPBootMode = NAND , PSP bootloader here means the U-Boot, which will also be loaded from NAND? 3. This u-Boot inturn would load the Linux kernel from NAND? 4. Most importantly , how will UBL know from which place on NAND to load the u-Boot? and How will u-Boot know from which place to load the Linux kernel, since NAND is not a Random access device? regards -Nitin Get your new Email address!

Re: davinci_i2c_read/write from atomic context
Thanks, That works. But shouldn't the i2c_read/write functions be made safe in
atomic context?

I use a workqueue like:
static void tsc_workqueue_handler(struct work_struct *work)
{
tsc2004_ts_rx(); //includes some i2c transfers
}
DECLARE_WORK(tsc_wq, tsc_workqueue_handler);
static irqreturn_t tsc2004_ts_irq_handler(int irq, void *dev_id)
{
/*
* Schedule the workqueue for I2C transfers
*/
schedule_work(tsc_wq);
/* kick pen up timer */
mod_timer(penup_timer,
jiffies + msecs_to_jiffies(TSC2004_TS_PENUP_TIME));
return IRQ_HANDLED;
}
