Has anyone got the Y/C (J1 pins 62 and 63) video output working on the Gumstix. I looked at this thread : http://gumstix.8.n6.nabble.com/Composite-video-td4948831.html and entered: setenv mmcargs setenv bootargs console=ttyS2,115200n8 mem=96M@0x80000000 mem=128M@0x88000000 omapfb.mode=tv:ntsc omapdss.def_disp=tv omapfb.tvcable=svideo root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait but no video signals were present at the Y and C outputs.

Sold wires on Tobi and tried TV signals out. Image output is rather noisy but it works. Switching is LCD or DVI to TV done by script.

I have already have the outputs connected to a y/c to composite filter by Maxium for the best possible conversion. I need to know what the scrips are. Do you happen to know? -- View this message in context: http://gumstix.8.n6.nabble.com/Getting-Y-and-C-outputs-working-on-WaterStorm-tp4965818p4965821.html Sent from the Gumstix mailing list archive at Nabble.com. |

Could you share which Maxim chip you use and in which configuration ? Brahim -- View this message in context: http://gumstix.8.n6.nabble.com/Getting-Y-and-C-outputs-working-on-WaterStorm-tp4965818p4965830.html Sent from the Gumstix mailing list archive at Nabble.com. |

Sure. Its a MAX11503. A demo pcb is available from Digikey. When I get output I'll post a pic of it. BTW, I figured out the #1 reason for no video is that a have a console build. Im baking a desktop build now. -- View this message in context: http://gumstix.8.n6.nabble.com/Getting-Y-and-C-outputs-working-on-WaterStorm-tp4965818p4965831.html Sent from the Gumstix mailing list archive at Nabble.com. |

Well.... Followed the DSS2 SYSFS Examples guide and was able to turn on the output, but its hardly NTSC. Im getting a downward ramp of about 100ns period. Im using a FE with a date code of R3358, which should have the video output ability. Any ideas? -- View this message in context: http://gumstix.8.n6.nabble.com/Getting-Y-and-C-outputs-working-on-WaterStorm-tp4965818p4965835.html Sent from the Gumstix mailing list archive at Nabble.com. |

My signal if very clean (as viewed from a oscope). I cant figure out how to use gatreamer to output video there. Anyway, i got mine directly from Maxim.
