You can safely copy the U-Boot section from one SD card to another using the dd command. Typically, U-Boot is stored within the first few megabytes before the first partition, so cloning the first 4MB is usually enough. You can do this by running sudo dd if=/dev/sdX of=uboot.img bs=1M count=4 and then sudo dd if=uboot.img of=/dev/sdY bs=1M count=4, replacing sdX and sdY carparkingmultiiapk.com with your actual device names. This method ensures you capture the full bootloader region. If you want to be more precise, refer to your board’s documentation for the exact offset and size of the U-Boot image.
