3.3 Generating the eMMC tisdk-tiny-image.img

Follow the instructions below to create a tiny file system image (tisdk-tiny-image.img) from the tisdk-tiny-image-j7-evm.tar.xs.

# Below code needs to run on the HOST machine
 
# Create an empty image file, seek value will create an image of that size. Typically 100MB should be enough.
# Size will should be slightly greater than size of untarred tisdk-tiny-image-j7-evm.tar.xz + size (DTBs + Kernel image)
dd if=/dev/null of=tisdk-tiny-image.img bs=1M seek=100

# Add a filesystem to it
mkfs.ext4 -F tisdk-tiny-image.img
 
# Mount it on your local machine to copy DTB and Kernel image
mkdir example_mnt_pt
sudo mount -t ext4 -o loop tisdk-tiny-image.img /home/karan/yocto-build/example_mnt_pt
 
# Untar tisdk-tiny-image-j7-evm.tar.xz on the mounted file system which is currently empty
cd example_mnt_pt
sudo tar xvf ../tisdk-tiny-image-j7-evm.tar.xz
 
# Copy DTB, DTBOs and Kernel Image for your platform
sudo cp /media/karan/rootfs/boot/Image* ./boot
sudo cp /media/karan/rootfs/boot/*dtb* ./boot
sync

# Unmount the image, now the tisdk-tiny-image.img is ready
cd ../
sudo umount /home/karan/yocto-build/example_mnt_pt
