Orange Pi rv2 with X1 cpu

[bartman]

Is there a known path to build an image for the Orange Pi RV2?

• The official site
• User manual PDF

Booting from the provided Ubuntu 24.04 I can see...

Linux orangepirv2 6.6.63-ky #1.0.0 SMP PREEMPT Wed Mar 12 09:04:00 CST 2025 riscv64 riscv64 riscv64 GNU/Linux

(not sure yet if this "ky" CPU support is upstreamed)

Not quite the same but maybe it helps for inspiration: #1409

Doesn't seem like there's upstream support yet, would need to use custom kernel from https://github.com/orangepi-xunlong/linux-orangepi/tree/orange-pi-6.6-ky
