Nope, a few BBB's escaped GHI with a bad eeprom programmed.. GND TP4 (between Ethernet and barrel plug) then run this "one" command as root: ***** dd if=/opt/scripts/device/bone/bbb-eeprom.dump of=/sys/devices/platform/ocp/44e0b000.i2c/i2c-0/0-0050/eeprom ***** ^ This line will get word-wrapped by gmail/googlegroups,etc Regards, -- Robert Nelson https://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.
