We really shouldn't need the eeprom either. We can actually override the eeprom, do either of these work when you add them to /boot/uboot/uEnv.txt First part disables the hdmi, 2nd enables the lcd4 optargs=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN capemgr.enable_partno=BB-BONE-LCD4-01:00A0 optargs=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN capemgr.enable_partno=BB-BONE-LCD4-01:00A1 Regards, -- Robert Nelson http://www.rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
