New to beaglebone and I prepped the card with my own yocto based core-minimal build, so I certainly may have done something wrong on my end.
The device boots up fine with the debian package that ships in flash. I did not blow that away. I prepped the card based on https://www.yoctoproject.org/download/texas-instruments-arm-cortex-a8-development-board-beaglebone and some older instructions at https://code.google.com/p/beagleboard/wiki/LinuxBootDiskFormat (I have tried a couple different times now) My result SD card looks okay $ sudo fdisk -lu /dev/mmcblk0 Disk /dev/mmcblk0: 3965 MB, 3965190144 bytes 255 heads, 63 sectors/track, 482 cylinders, total 7744512 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000c1e3c Device Boot Start End Blocks Id System /dev/mmcblk0p1 * 63 819314 409626 c W95 FAT32 (LBA) /dev/mmcblk0p2 819315 7743329 3462007+ 83 Linux When I do boot the device to debian the SD card itself is visible and /media/root and /media/boot seem fine.The problem is if I boot while pressing the boot order toggle button I get nothing. None of the 4 activity LED lights turn on at all. All I see is the power light. I have a serial cable on order, but in the near term I am trying to diagnose if there is a hardware problem here or if I am doing something wrong. 1) If I am simply trying to boot from SD card (not flash internal eMMC) is there a length of time I need to hol down the bott order toggle switch? I have tried really short presses as well as upwards of a minute. 2) Is there anything I am completely missing here? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
