Easiest way to flash eMMC

[csphx]

All is well that ends well .... 
  
  Yesterday I successfully cloned my working
  rock64 debian stretch minimal 16 gb sd card
  to a 32 gb eMMC module using the dd command
  running on a debian buster pc .... 
  
  I used two usb3 card readers in a powered
  usb3 hub with the target eMMC attached
  to a  [sd|eMMC ] adapter .... 
  
    # dd if=/dev/sdc of=/dev/sde bs=3M conv=notrunc,noerror status=progress

  The  dd  copy took about 13 minutes 
  and the eMMC booted with no problems .... 

  This was my first experience with an eMMC module
  and I did find it a bit tedious first attaching it
  to the  [sdc|eMMC]  adapter and then inserting it
  into its designated slot on the rock64 board
  due to its small size ....
