Hi! I only would like to know if I could connect a composite video input (not S-VIDEO) on the expansion board, and what settings should I put inside the TVP5151 to have a PAL input configuration... I\\\'m planning to use it as a secondary input in a software I\\\'m writing, so I would like to write the commends for this basic setting... Thanks!

    Hi For select the SVIDEO configuration you should use this command: tvp5150_write(sd, TVP5150_VD_IN_SRC_SEL_1, 0x01); For select composite channel A: tvp5150_write(sd, TVP5150_VD_IN_SRC_SEL_1, 0x00); For select composite channel B: tvp5150_write(sd, TVP5150_VD_IN_SRC_SEL_1, 0x02); Cheers Manel

    Sorry, I will explain better myself... I would like to use a Ubuntu distro (to have the GNOME environment) with the ISEE kernel (I\\\'m working on the 2.6.35.10-0 version). So I have downloaded the X-loader and U-boot binaries, and Kernel sources. With the Virtual Machine I have compiled the kernel with the igep0020_defconfig configuration. Now I would like to use the TVP5151 with this kernel version, because I would like to use My Own expansion board with a different display. Now I\\\'m testing some features one by one, like touch panel, tft interface for lcd, backlight (I have used a different IC for the backlight), and the TVP5151 video interface. I didn\\\'t yet bought the expansion board, but I have the same TVP5151 schematics, so I only would like to test its digital interface with the OMAP processor (not the video quality as I have done myself the signal path for analog inputs...)? I have tried to download/compile the different kernel you pointed in the [url=http://labs.igep.es/index.php/How_to_get_the_Poky_Linux_distribution#TVP515]http://labs.igep.es/index.php/How_to_ge ... ion#TVP515[/url] but when I try to launch the git checkout -b origin/media-0005-sensors media-0005-sensors I receive an error, so I can\\\'t continue... Is there some way to test the TVP5151 with the MAIN IGEP KERNEL? Regards

    I suggest you start sending i2c commands to the TVP5151 ... Manel

    hi! Yes, you just suggested me, but how can I send this commends? is there a way to send them with the terminal, serial terminal or Poky root terminal for example? Or should I use the YAVTA software ([url=https://github.com/fastr/yavta]https://github.com/fastr/yavta[/url])? I don\\\'t think the YAVTA could write i2c commands...

    Yes, I already added the TVP5151, with all its signals. I haven\\\'t added any sort of Pull up Resistor on the I2C bus, as I haven\\\'t seen them on your expansion board schematics. I had compiled the kernel (isee 2.6.35.10-0 version) with the \\\"igep0020_defconfig\\\" and installed the modules in the rootfs of a uSD card of a Ubuntu distro, made with rootstock (lxde). The only changes I have done to the schematic of the TVP5151 is only one input source connected, that I would like to use as RCA connector input (composite video in). Our company chooses you development board because in the description you mentioned the OMAP-camera interface, and in the expansion board I have seen the TVP5151 decoder... We are very very late with the development of our product, and we need some more help!!

    You must use this kernel: linux-2.6.35.y-omap3isp Not 2.6.35-10 Due the ISP framework interface it\\\'s included in the first one ...

    Hi What do you mean by \\\"you can contact us directly in support or sales account and we\\\'re open to discuss the support required for your company ...\\\". Isn\\\'t this forum the location for support? You have a special support department for companies? How does that work?

    Manel[/quote] I\\\'m not sure to understand... in the \"linux-2.6.35.y-omap3isp\" git tree, under the driver/video/display/ I don\\\'t see any files, so I assume that it is not supported the lcd interface for your LCD (for example)... I will try with this kernel version, anyway, but I don\\\'t understand how it can be possible to use your expansion board with a lcd and the TVP5151 decoder together, as the support for the expansion board is in the 2.6.35.10-0 version... :shock:

    linux-2.6.35.y-omap3isp it\\\'s a branch from 2.6.35.10 and all from this one it\\\'s included in the first one. As you can see here: [url=http://git.igep.es/?p=pub/scm/linux-omap-2.6.git;a=blob;f=arch/arm/mach-omap2/board-igep0020-22.c;h=c10d2f1d09dfee4b29a97a4c9ca5265fdc5f9bc2;hb=refs/heads/linux-2.6.35.y-omap3isp]http://git.igep.es/?p=pub/scm/linux-oma ... y-omap3isp[/url] The expansion it\\\'s included ... but if you need other missing feature you can port it from 2.6.35.y due it\\\'s the same kernel.
    What do you mean by \"you can contact us directly in support or sales account and we\\\'re open to discuss the support required for your company ...\". Isn\\\'t this forum the location for support?
    I mean this is our free support service but It not mean we offer other kind of support services ... ISEE it\\\'s a design & manufacturing company and we provide some services for free like this and other paid services that include other kind of support levels ... * Support for your design. * Custom BSP. * Custom Drivers or support for other S.O. * Fast Response & confidentiality ... * Custom design services. * Manufacturing ... * Consultancy ... * Other services ... This services can be provided for us or our partners like \"free electrons\" Cheers Manel

    Hi! I have done a \\\"clone\\\" of your repository with: [code] $ git clone git://git.igep.es/pub/scm/linux-omap-2.6.git $ cd linux-omap-2.6 $ git checkout linux-2.6.35.y-omap3isp [/code] after this, I have all the sources of the linux-2.6.35.y-omap3isp branch, right? now, I would like to know if it is safe to makes some mods inside those folders/files, without compromising the \\\"original\\\" branch, and test by myself all my mods...and what kind of commands I shouldn\\\'t type as I don\\\'t want to upload my mods in your repositories, as I have to change some important files like Makefile or KConfig... Regards, Simone

    It is the first time I work with GIT in a serious way, using it to clone and ALSO modify some projects. I would like to use also gitorious or Github, but the free versions are open source only (no private hosting) and I would like to know if I could clone your repositories and put them in my gitorious or github with my mods, in a public repo Thanks for your feedback Ps: I have seen in deeper that the linux-omap-2.6.35.y-omap3isp has got all the panels that are present in the \\\"official\\\" kernel... previously I was looking in a different place!
