i am using armbian 24.2.1 debian bookworm inn orangepi 5b. At first i used sd card to boot. then i wanted to use emmc to boot. so i went to armbian-config and install os in emmc from there from sd card. now it is booting from emmc if the sd card is not connected but if the sd card is connected it is booting from sd card. The worst part is, if i connect a sd card where there is no OS, it will not even boot.
How can i set a order like if there is bootable os in emmc boot from there and use the sd card as storage if not boot from sd card ?
