Hi there, I recently just came across this thread and is pleasantly surprised and happy that there are still on-going developments on our old-ish RK322x devices!
Before seeing this thread, I was rockin' a MX4-V10 RK3229 (?) Android Box with an old respeaker img on a sd card which I found months ago.
Pictures of the android box and internals for reference: MX4-V10 Pics
I actually already tried to burn "Armbian_20.05.0-trunk_Rk322x-box_buster_current_5.5.16_minimal.img.xz" into an sd card and the box failed to boot. I then burned "LE_bootloader_Armbian_20.05.0-trunk_Rk322x-box_buster_current_5.5.16_minimal" into an sd card and the box successfully booted.
It seems to be working fine upon initial check but I just wanted to clarify a few things so I can do over the setup in case there's a more optimal/correct way of doing it:
1. Does my box have NAND or eMMC internal storage?
2. If NAND, is it ok to use any of the 3 types of images (focal legacy, buster legacy, buster mainline)? I'm a bit confused on "NAND is available only on legacy" on 1st post.
3. Also if NAND, which is better:
a. Use newly created Multitool and install Jumpstart. burn 1 of the 3 original img to sdcard and plug in to the box.
b. Use the IMGs posted by @Maker39 with the built in Libreelec bootloader
4. Finally, upon installation, which of the boards do I pick when running rk322x-config? Is it ok to pick again after initial selection? If I were to do trial and error, what do I watch out for to check that I picked the correct board?
Thanks so much!
