The current state of the device

Boots with uniLoader and postmarketOS edge.

Mainline kernel boots at cpu0 with a framebuffer display, brings up secondary cpus and mounts rootfs at sdcard. Currently EMMC dead, touchscreen dead (no drivers), telnet dead, ssh dead, making it impossible for now to actually use the debug shell and/or the console. YAY

Too much versions of a single phone

There is THREE (as far as i know) versions of dandelion: M2006C3LG, M2006C3LC and M2006C3LI. (maybe more, im not sure) The phones can have a different firmware (R vendor and Q vendor) I've already saw the difference. In Q and R framebuffer has A DIFFERENT address. R vendor has more reserved-memory nodes than the Q The phone can have DRAM from 2GB to 3GB and up to 4GB And it can have 32GB storage, 64GB and the 128GB

[Then, on which version you (evilMyQueen), booting linux?]

Xiaomi Redmi 9A (xiaomi-dandelion) M2006C3LG R vendor 2/32GB with the adomerle linux kernel fork (needs rebase tbh)

"Hello" tested it on M2006C3LG and everything works the same (R VENDOR) [Which phone do i have?]

In the settings, you can find how much RAM and storage you have R vendor (most AOSP is here) is (i think) is MIUI 12.5, while Q vendor is MIUI 12 To check the exact model, just open settings, open "about phone" and scroll until you see "Device name"
