Hi I've seen Overo has support to TV signal (composite video). But when I enabled kernel parameters "omapdss.def_disp =" tv "omapfb.mode = TV: PAL", I get a black and white signal with a lot of noise. Has anyone achieved run the composite video signal? Thanks |

I tested a R3560 Overo WaterStorm for s-video with success.

What is the kernel version you have? I've been testing on 2.6.29 and 2.6.34 and does not work. In the kernel code that I used, the NTSC setting has been disabled: int r; #ifdef CONFIG_OMAP2_DSS_VENC if (strcmp(mode_str, "pal-16") == 0) { *timings = omap_dss_pal_timings; *bpp = 16; return 0; } else if (strcmp(mode_str, "ntsc-16") == 0) { *timings = omap_dss_ntsc_timings; *bpp = 16; return 0; } else if (strcmp(mode_str, "pal") == 0) { *timings = omap_dss_pal_timings; *bpp = 0; return 0; } else if (strcmp(mode_str, "ntsc") == 0) { *timings = omap_dss_ntsc_timings; *bpp = 0; return 0; } I tested a R3560 Overo WaterStorm for s-video with success.

Hi Ash, I just received a few R3358 Overo FE sticks. Is it possible to run DVI or LCD WITH the Analog video output enabled at the same time? Can you advise what are the changes needed in u-boot or kernel that needs to be done to achieve this? Many thanks in adv.

I believe it is possible...but I don't know how to do it :(. I tried messing around with the dss options in SYSFS and was able to switch on and off displays (HDMI + s-video) but was never able to get both running concurrently. I suspect much of the kernel machinery is in place but perhaps some additional patches to DSS are required? I'd certainly love to know if anyone has managed to drive two screens with an Overo before. --Ash |

But I don't know what should I play with in u-boot and other some other parts of the kernel to get it to work.. You clue to getting the analog setting for u-boot is a good point for me to try out the analog video first.. Any other mailing list that I should post this in? -- Regards, James Ang |

Ask what Alberto Caro (alberto.caro.m at gmail) has done. Here is his post: Hi I've seen Overo has support to TV signal (composite video).

Also, ask Mark Russell (bluesmurfs78.gumstix at gmail): Hi All, Currently, I am trying to interface an analog video decoder (TVP5146 to be exact) to the 27-pin camera connector on my Overo Fire COM. I know that this interface works on the OMAP3530 EVM Board but I have problem trying to find the necessary source codes to build on to the omap3-desktop-image bb file which i am currently using to make the TVP5146. I am using version 2.6.39 for my desktop image... Will anyone that have experience working on video decoder to Overo give me some hints and guidelines on how should i do to get my project working?? Really appreciate your help!
