eMmc boot on M4

I’m currently running Ubuntu Desktop from SD card. Attempting to load to and boot from emmc without success, has anyone got this to work?

My process has been to:

1- load tgz file of image on USB, and use bpi-copy 2- load tgz of image on USB, and unzip img | dd of=/dev/mmcblk1 bs=10mb

Both methods result in both LEDs remaining solid without ever proceeding
