Can I develop a board with the Snapdragon 410 and a eMMC 5.0?

Hi @andribiotic

eMMC 5.0 is a superset of eMMC 4.5. An eMMC 5.0 part should work, but I haven;'t tested it. You won’t be able to access some of the eMMC 5.0 new features such as HS-400 mode. The new DS signal can be left not connected since this is only used in HS-400 mode.

Thank you @ljking for your response. I’ll read the documentation from JEDEC about eMMC 5 to be sure.
