Concerns before trying to boot Armbian from SD card on GS King-X

[marfalk]

Hello everyone,
I would like to test Armbian on my GS King-X (S-922X). I have prepared a SD Card by using Armbian Imager. Then I have followed the instructions here:

• modified the "armbi_boot/extlinux/extlinux.conf" file, specified: "fdt /dtb/amlogic/meson-meson-g12b-gsking-x.dtb";
• copied "u-boot-s905x2-s922" as "u-boot.ext".

 

Now before trying to make the device boot from the SD Card, I would like to know:

1. If I do not install Armbian to the internal eMMC, will I be able to boot back to Android, by just removing the SD Card and powering off then back on the device?
2. Later, if I decide to install Armbian to a USB drive or an internal SATA Hard-Drive, will I be able to boot back to Android, or it will modify the boot loader in a way that it will not be possible?

 

Thank you in advance
