Booting official Debian on RP64

[TRS-80]

Can you boot Armbian focal from eMMC. In my case it simply doesn't work.
Using this Uboot by the way:

Armbian has a (perhaps unfortunately named) tool called nand-sata-installer which is what you are probably looking for. It should install to various targets on supported devices.

Again, if it is supported, Armbian will have already figured out the best boot loader, kernel, patches, etc. to use. For less experienced (or even medium, like myself) people, that is probably the best option. And if you are more experienced / have better ideas, IMO it will be better to contribute them to Armbian rather than everyone working on their own separately and information gets lost, precious time and energy wasted on experiments which others already did, etc...
