Run Ubuntu 23.10 on Milk-V

[ww898]

Hi there,
Is there manual to install Ubuntu 23.10 (see https://ubuntu.com/download/risc-v) on Milk-V? I tried "StarFive VisionFive 2" image (ubuntu-23.10-preinstalled-server-riscv64+visionfive2.img) and the boot process failed. Can anybody help me with it?

You might try the u-boot command efidebug bootmgr

I don't think it would work, but there is an EFI System Partition so... something might happen.

I ran Ubuntu on another StarFive VisionFive 2 board. The only problem was with u-boot (see https://wiki.ubuntu.com/RISC-V/StarFive%20VisionFive%202):

Vendor U-Boot releases are available at https://github.com/starfive-tech/VisionFive2/releases/. Or you can build U-Boot from the upstream source as described in the online documentation.

As both for with some vendor U-Boot releases as well as with the upstream U-Boot v2023.10 we found some issues we have prebuilt a binary package u-boot-starfive available in ppa:ubuntu-risc-v-team/release.

Ubuntu 23.10 is better than Debian because it has the new versions of libc/libstdc++.
