Micro-SD to EMMC Adapter EMMC Module to Micro-SD Adapter for NanoPi K1 Plus Development Board Flash OS to EMMC Module: Extract an image file and run on a Windows PC. Connect an EMMC module to a Micro-SD to EMMC adapter, insert this Micro-SD adapter into a Micro-SD to USB adapter, and connect the USB adapter to the PC. Run the Win32DiskImager utility as administrator. In the utility's main window, select the drive of the Micro-SD adapter, choose the desired image file, and click "Write" to begin flashing the EMMC module. Once flashing is complete, remove the EMMC module from the adapter. Insert the EMMC module into the EMMC slot on a NanoPi K2 and power on the board using a 2A power source. If both the green LED and blue LED remain solid, the NanoPi K2 has successfully booted. When a K2 board has both a TF card and an EMMC module inserted, it will always boot from the EMMC module. To boot from a TF card, insert only the TF card and leave the EMMC slot empty.
