@zygoon I believe a discussion is still ongoing about Vector 0.7.* vs 1.0 compiler support (I did not have time to dig deeper into this yet so I'm unsure about the current state, but general notion is NOT to support v0.7.* -> start digging here https://github.com/brucehoult/riscv-gnu-toolchain).
If you are ok with trying RV kernel builds etc, LicheePi is very good start now.
On the other hand probably a new gen of devices with rvv1.0 CPUs will get released later this year, so it might be ok to wait for a little while 🙂
