I would like to understand how to set default booting method to USB, and in case there was no bootable USB device detected, continue to run from eMMC.
Following l4t documentation, I have configured boot-order to “sd”, “usb”, “net”, “emmc” in cbo.dts, built DTB and flashed the board with -k CPUBL-CFG. But then, depending on the flash method it either boots always from eMMC (neglecting USB drive) or stops if no such USB device was found.
How to properly use boot-order property of cbo.dts file?
Thanks a lot!
