Booting with Firmware SD card

Using latest release from https://github.com/starfive-tech/VisionFive2/releases/tag/VF2_v2.11.5

Instructions on installing the firmware from https://forum.rvspace.org/t/visionfive-2-debian-image-released/994/75

Must select SD as boot medium with the board jumpers, because otherwise it cannot boot

Boot with Debian SD card

Does not work on the VisionFive 2 out of the box --- need to update firmware first (see above)

Using Debian image 202303 on an SD card (starfive-jh7110-VF2-SD-wayland.img.bz2)

Card written with:

$ sudo dd if=starfive-jh7110-VF2-SD-wayland.img of=/dev/sdb bs=8M status=progress

(Note that https://github.com/starfive-tech/VisionFive2 suggests bs=4096)

After first boot, the root partition must be resized, so that it extends to the whole SD card: https://doc-en.rvspace.org/VisionFive2/Quick_Start_Guide/VisionFive2_QSG/extend_partition.html

Update then to Debian unstable: https://www.ports.debian.org/archive

Halt the system, and save the contents of the SD card:

$ sudo virt-sparsify --tmp /root --verbose --format raw --convert qcow2 /dev/sdX visionfive-2-debian-ports-updated.qcow2

To reload:

$ sudo qemu-img convert -f qcow2 -O raw visionfive-2-debian-ports-updated.qcow2 /dev/sdX

Install custom kernel

After the update, reboot and install Linux kernel with SECCOMP enabled: https://rvspace.org/en/project/VisionFive2_Debian_Wiki_202303_Release

Once new kernel is in place, delete the old kernel DEBs, and save the SD card contents:

$ sudo virt-sparsify --tmp /root --verbose --format raw --convert qcow2 /dev/sdX visionfive-2-custom-kernel.qcow2

Booting with Debian eMMC

No luck yet.

Like above, but with an eMMC module instead.

Connecting the eMMC module to the board using J99 (the one to the right). It only fits on this one.

Serial port setup

The dongle gets recognised as /dev/ttyUSB0, it seems, so

$ sudo minicom -D /dev/ttyUSB0 -b 115200
