## VisionFive 2
Documentation: https://doc-en.rvspace.org/Doc_Center/visionfive_2.html
### 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
### Network interfaces
