Hi, There is a stupid PCB problem with the video in pixel port: we connected P[7:0], but the video decoder outputs on P[15:8] when in 8-bit mode. Nobody spotted this one :(
Besides that, the decoder circuit appears to be working: the crystal oscillator is stable and clean (checked on scope), the decoder chip responds to I2C, and when fed a video signal it gets detected and reported in the I2C registers and the pixel port clock and sync signals toggle. Since P[7:0] are high-impedance when the chip is in 8-bit mode, I will buy some thin wire tomorrow and use it to connect P15->P7 ... P8->P0 so I can continue with the video input bring-up. Soldering wire to 16 pins on a QFP sure sounds like a lot of fun, but with some patience I should be able to make it... I am still listing PCB errors and possible improvements here: http://www.milkymist.org/wiki/index.php?title=RC1_errata Sébastien _______________________________________________ http://lists.milkymist.org/listinfo.cgi/devel-milkymist.org IRC: #milkym...@freenode Webchat: www.milkymist.org/irc.html Wiki: www.milkymist.org/wiki
