I follow this link to flash emmc through sd card. It work good.elinux.org/BeagleBoardUbuntu
But I have built my custom sd card system already ,how can I flash it into emmc.
there is another link for beaglebone black .
I try to Create initramfs Filesystem (and Kernel), Download the tiny flasher filesystem (https://gforge.ti.com/gf/download/frsrelease/1303/7970/am335x_tiny_filesystem.tar.gz) and save it.
but this link for tiny flasher system seem broken .
