After trying everything else (hard-coding your EDID, and using a DVI cable), I managed to find a board with Silicon Revision 1.0, and it's failing more or less as you described: - 640x480 works - 1920x1080p fails I also see those "timeout waiting for flip irq" messages whenever switching to a resolution that doesn't function. I'm not sure why, but it's probably time to grep through those pesky tests for tapeout: imx_get_soc_revision() == IMX_CHIP_REVISION_1_0 TO 1.0 **did** work at 1080P in the older kernels. Regards, Eric
