Step2: Copy the kernel image and device tree to the eMMC card
sudo fdisk -l to list the disks that are accessible on board.
Mount the eMMC card partition that contains Linux kernel images and device tree.
Use the command cat /proc/partitions to see the list of devices, their partitions along with their sizes to make sure that the correct device and partition name have been chosen.
The eMMC storage drive in the Linux PC is detected as /dev/sdX, where X is a letter such as a, b, c. Make sure to choose the correct device name, because data on this device will be replaced.
If your Linux host machine supports read/write eMMC card directly without an extra eMMC card reader device, the device name of eMMC card is typically mmcblk1.
In general, the Linux kernel images and device tree are stored in the second partition of the eMMC device (mmcblk1p2). For detail on storage layout on SD/eMMC/USB/SATA for LSDK images deployment, refer to section "LSDK memory layout and Userland" in
