Hi, It seems the DDC (Display Data Channel) interface also works on the board. I was unable to completely test it - strangely, my monitor responds to I2C addresses 0x92/0x93 and 0xb2/0xb3 which I don't find in any spec, and I don't have another monitor to test. But the fact that the monitor reliably responds to fixed and consecutive I2C addresses means that the electrical interface is probably OK.
Michael, can you try the following bitstream and demo firmware on your board and screen: http://www.milkymist.org/ddctest To load the bitstream, use Impact (assign new programming file to the FPGA, then "Program") and use flterm (found in the "tools" directory of the MM SoC source tarball) to load the new firmware, with a command such as flterm --port /dev/ttyUSB0 --kernel boot.bin Then, the "edid" command in the firmware should dump the EDID block of your monitor. Tell me if it works. Thanks, Sébastien _______________________________________________ http://lists.milkymist.org/listinfo.cgi/devel-milkymist.org IRC: #milkym...@freenode Webchat: www.milkymist.org/irc.html Wiki: www.milkymist.org/wiki
