I have a Milk-V Mars but it really isn’t performant enough for any task I have for an SBC. Distro support seems to be a pain too, as the provided Debian image isn’t meant to run on repos aside from a Debian snapshot from 2022.
I really do hope things improve. I’m planning on moving over to an RK3588 ARM board for desktop daily drivering but one day I’m hoping a decently affordable RISC V alternative will turn up.
