This lineup of SBCs contains SoCs with the CPUs that use the RISC-V open computing ISA.
This Wiki contains the necessary information a user needs to know before using Rocky Linux on the VisionFive 2 SBC.

To install Rocky Linux on the VisionFive 2 SBC, there is one pre-requisite that needs to be satisfied. That is to update the board firmware to v2.11.5.
Editor's note: StarFive (the hardware vendor) is almost done sending in mainlining patches for u-boot and we should be able to switch to upstream u-boot soon. Our u-boot package for the VisionFive 2 should automatically update the board firmware to whatever version we support. But the following section is present nonetheless, for the users who have an outdated firmware than what we (Rocky Linux) have a minimum spec bar for.

sudo mount /dev/sdX4 temp-dir
sudo cp u-boot-spl.bin.normal.out visionfive2_fw_payload.img temp-dir/root/
sudo sync; sudo sync; sudo sync; sudo sync;
sudo umount temp-dir
Eject the SD card from your computer, insert it in your VisionFive 2 and power it up. The green LED should start blinking to indicate successful board power-up.
Plug the network cable in the Ethernet port that is next to the HDMI port. (The other port has DHCP-related issues with early firmware.)
ssh root@<IP_ADDRESS> (passwd: starfive)
Run the command cat /proc/mtd and you should have the following output:
dev: size erasesize name\nmtd0: 00020000 00001000 \"spl\"\nmtd1: 00300000 00001000 \"uboot\"\nmtd2: 00100000 00001000 \"data\"\nIf and only if the partition information given above matches with yours, update the spl and uboot partitions using the following commands:
flashcp -v u-boot-spl.bin.normal.out /dev/mtd0\nflashcp -v visionfive2_fw_payload.img /dev/mtd1\nThe board firmware has now been updated!

The correct system time is set later at boot once network connectivity is established and an NTP server is reachable.

Until 9.3 is released, or if the system is still on 8.x, the patch can be manually applied to all versions.

Afterwards, Sherif began working with Pablo to build a generic arm kernel for more than just RPis. GenericArm image is being built with Empanadas, but not widely used. It should support Rpi as well as others.
As a rule, we cannot rely on EPEL dependencies, and will need to pull them into our build roots. We should work on/request tooling to aid in these operations--i.e., something to identify dependencies, and perform imports of them for us.
