2. Update upgrade EMMC inside the system

Although we are using the image of SD card, but due to the Lemaker guitar early board of the factory EMMC system used in the old version of the firmware, the new and old firmware in the display frame has a big change, can not be mixed, Therefore, it is recommended that the board EMMC inside the system mirror upgrade to the latest available on the current Web site of any of the latest version of the system.

eMMC inside the system upgrade installation is completed, first plug in the power, do not plug SD card, confirm eMMC inside the system is running up, and then disconnect the power. If the EMMC system is running, you can start the next step.

The Windows computer that I use. Download a sdformatter software and Win32 Disk Imager. (1) The SD card through the USB card reader inserted into the computer, it is recommended that the USB card reader, otherwise it will cause the burn unsuccessful. The
(2) formats the SD card using the Sdformatter software. The
(3) loads the downloaded system image using the Win32 Disk imager software and is burned to the SD card.
Unplug the SD card after successful burn.


Of course you can also use Linux computer to complete the above steps, you can first through Fdisk and MKFS and other commands format SD card, and then through the DD command to burn system mirroring. I believe that those who play Linux should be more familiar with these commands.


4. Insert the SD card into the guitar board and power on the boot. Because snappy Ubuntu core does not have a desktop, the HDMI output shows command-line mode.
