I am seeing the same behavior with an SD card with u-boot from current meta-ti master (MLO-beaglebone-2014.07-r1+gitrAUTOINC+8bd803d2c5)

I partition the cards and create the boot/root partitions with:

sudo dd if=/dev/zero of=${MMC} bs=1024 count=1024
( echo ,9,0x0C,* ; echo ,,,- ) \
  | sudo sfdisk -D -H 255 -S 63 ${MMC}

${SUDO} mkfs.vfat -F 16 -n boot ${MMC}1
${SUDO} mkfs -t ${FSTYPE} -L rootfs ${MMC}2

${SUDO} cp -p MLO u-boot.img ${MPROOT}/boot

This process works with poky master and yocto-bsp on beaglebone.

I recall from long ago that some TI systems were picky about the partitioning of the boot media.

This is not true for recent Sitara SoCs:

Would somebody with an SD card image that boots the current meta-ti master provide the output of fdisk -lu from it, or a pointer to instructions for doing the formatting?  For reference, what doesn't work is:

llc[325]$ sudo fdisk -lu /dev/sdh

255 heads, 63 sectors/track, 959 cylinders, total 15415296 sectors

I'm using the following partition layout (both working on eMMC and sdcard with u-boot_2014.07.bb):

# fdisk -lu /dev/mmcblk0

Disk /dev/mmcblk0: 1920 MB, 1920991232 bytes, 3751936 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 label type: dos
Disk identifier: 0x00000000

        Device Boot      Start         End      Blocks   Id  System
/dev/mmcblk0p1   *          63       80324       40131    c  W95 FAT32 (LBA)

Thanks.  That does appear to be an eMMC partition, which probably shouldn't matter, but I replicated the configuration on a 2GB class 4 uSD card, and an 8GB class 6, and it doesn't work on either one.

llc[77]$ sudo fdisk -lu /dev/sdh

Anybody got a uSD partition layout that works?  I'm suspecting an issue with the heads/sectors/cylinders configuration.

(FWIW: I'm also using u-boot-staging-ti, as that's the default for beaglebone on the master branch.)
