Hi All,

We are trying to boot up the board through sd card. But its booting up normally with the pre-built Android 10. Could anyone help regarding how to boot up through sd card. Is there any switch which needs to be switched on to boot up from the sd card.

Please look ito it. 

Thank You,

Regards,

Mandira
