I may be experiencing something similar. (I might also be completely misunderstanding what to do...)
SD card written with "Debian Image Testing Snapshots, 2014-11-19 BBB Rev C (4GB eMMC) Flasher: lxde: x.yG Free" from elinux.org (i.e. downloaded with curl onto separate computer, decompressed via unxz, written to SD via dd if=/path/to/image of=/dev/sdx) SD card inserted in BBB with power down and all attachments removed. Boot button depressed while 5 v power plug inserted. Blue power light comes on, but nothing else happens. BBB boots normally when boot button is not depressed. I have ordered a standard FTDI cable but don't have it yet. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
