Apparently doesn't work for my device. Stock android of my device doesn't support multi-boot, until flashing a 3rd party rom. But after installing armbian to emmc it doesn't work again. Shrink image is not compression. It is not required, but a good practice. Refer to official Armbian release or other projects.

I didn't find any documents about how to boot from usb after a emmc installation or how to shrink the image file. Any official way to do that?

OK, after hours of work I fixed the problem. To boot from u-disk, edit /boot/uEnv.txt and change the partition label, for example, modify #APPEND=root=LABEL=ROOT_EMMC to #APPEND=root=LABEL=ROOTFS To reduce the image size, use resize2fs to shrink the file system, and use fdisk to change partition table, then the image file can be truncated from 5000MiB to 2.2GiB, which saves much space and time. It's very useful when you use a low-speed u-disk or less than 5000MiB.

Hi there, I have a S905M device, I installed Armbian_20.05.1_Arm-64_bionic_current_5.6.0-rc7_20200404.img to eMMC with install-aml-s905.sh and it works well, but it can't boot from u-disk any more, even holding the reset button when booting, is it possible to boot from u-disk? This image looks like a server version, but why is it so big, 5.24GB? Thanks in advance.
