'''<tt>password: alt</tt>'''


The graphical image with [https://en.wikipedia.org/wiki/Xfce XFCE] does not provides
  login: root
a preset password for the root user. At the first boot the user will be asked to setup
  password: altlinux
system manually through visual menu.


In the case of the developer image ('''builder''') there is an another user:
For images with graphics the user will be asked to complete the initial setup in a graphical setup wizard at the first boot. During configuration, you can set the timezone, root password, password for connecting to VNC (if launched via VNC), create a new user, etc. On boards without a graphics adapter the graphical setup wizard must be run via VNC.

The instructions on how to run these images on QEMU in [[#How to run on QEMU|this section]].


= '''How to run on QEMU''' =
* xfce: [http://nightly.altlinux.org/sisyphus-riscv64/tested/regular-xfce-latest-riscv64.img.xz riscv64]
In order to run the image on the QEMU system one need to follow these steps:


'''Step 1.''' Install QEMU with riscv64 support. For example, in the case of ALT x86_64 system: [http://sisyphus.ru/en/srpm/Sisyphus/qemu qemu-system-riscv-core].
== QEMU ==
 
'''Step 2.''' Get the [http://ftp.altlinux.org/pub/distributions/ALTLinux/ports/riscv64/Sisyphus/noarch/RPMS.classic/kernel-image-qemu-un-def-5.0.19-alt3.rv64gc.noarch.rpm Linux kernel for QEMU] and install it:
<source lang="shell">rpm --install <kernel package>.rpm</source>
After that, the Linux kernel for QEMU compressed with gzip could be found at /usr/share/qemu-riscv64/vmlinuz.
Decompress the Linux kernel:
<source lang="shell">$ gzip -d -c /usr/share/qemu-riscv64/vmlinuz > ~/vmlinux</source>


'''Step 3.''' Download one of the images for QEMU listed ([[#QEMU|above]]) and just replace <IMAGE> to the path of just downloaded qcow2c image:
The img.xz images must be unpacked and run according to the instructions: [[Ports/riscv64/QEMU]].
<source lang="shell">
$ qemu-system-riscv64 -nographic -machine virt \
                      -kernel ~/vmlinux \
                      -m 2G -smp cpus=4,threads=2,maxcpus=8 \
                      -drive file=<IMAGE>.qcow2c,id=hd0 -device virtio-blk-device,drive=hd0 \
                      -append "earlyprintk root=/dev/vda1 fastboot rootwait console=ttyS0 debug sunrpc.debug" \
                      -netdev user,id=eth0 -device virtio-net-device,netdev=eth0
</source>
In the case of the XFCE graphical image, the user needs to redirect incoming
TCP connections to the host port 5900 (VNC) to the guest port. One could do it
with the following command:
<source lang="shell">
$ qemu-system-riscv64 -nographic -machine virt \
                      -kernel ~/vmlinux \
                      -m 2G -smp cpus=4,threads=2,maxcpus=8 \
                      -drive file=<IMAGE>.qcow2c,id=hd0 -device virtio-blk-device,drive=hd0 \
                      -append "earlyprintk root=/dev/vda1 fastboot rootwait console=ttyS0 debug sunrpc.debug" \
                      -netdev user,id=eth0,hostfwd=tcp::5900-:5900 -device virtio-net-device,netdev=eth0
</source>


For information about how to connect to the VNC server please refer to the [[#VNC|"VNC" section]].
== HiFive Unmatched and Unleashed ==


= '''How to run on HiFive Unleashed''' =
Images write in instructions are available on the board pages: [[HiFive Unmatched]] and [[HiFive Unleashed]].  
This instruction assumes that the user is working on the computer with ALT Sisyphus installed on it.
In order to run the image on the HiFive Unleashed one need to follow these steps:


'''Step 1.''' [[#HiFive Unleashed|Download]] minimal system image with systemd, which is a ''tar'' archive with rootfs. To install the system one could choose between two options: [[#Automatic install on ALT Sisyphus|automatic install on ALT Sisyphus]] and [[#Manual install|manual]].
== VNC ==
Connecting via VNC (not the vnc provided by the qemu emulator) requires :


== Automatic install on ALT Sisyphus ==
* enable vnc mode in alterator-setup by uncommenting or adding a line to /etc/alterator-setup/config:
'''Step 2.''' Install the [http://sisyphus.ru/en/srpm/Sisyphus/alt-rootfs-installer alt-rootfs-installer].


'''Step 3.''' Run the <tt>alt-rootfs-installer</tt>. This script will automatically install the system on microSD card. For example, to install <tt>regular-builder-alpha20190329-riscv64.tar.xz</tt> image on <tt>/dev/sdX</tt> with log output to <tt>/home/user/alt-rootfs-installer.log</tt>:
<source lang="shell">ALTERATOR_SETUP_VNC=1</source>
<source lang="shell">
$ alt-rootfs-installer --rootfs=/home/user/images/regular-builder-alpha20190329-riscv64.tar.xz \
                      --media=/dev/sdX \
                      --target=HiFive-Unleashed-bbl --log /home/user/alt-rootfs-installer.log
</source>
<br>
After this procedure the /dev/sdX disk will contain two partitions. The first partition will contain bbl bootloader with Linux kernel, which is statically linked with bbl. The second partition will contain root file system.


Now, microSD card is ready to use with HiFive Unleashed.
or add a --vnc=1 argument for alt-rootfs-installer when it writes to a removable storage device.


== Manual install ==
* connect via a serial port and wait for information about the address and VNC connection password:
'''Step 2.''' Untar the /boot directory from the archive from ''step 1''. For example, in the case of minimal system image with systemd:
<source lang="shell">
<source lang="shell">
$ tar -xf regular-jeos-latest-riscv64.tar.xz ./boot
localhost login: ALTERATOR SETUP === VNC access enabled
ALTERATOR SETUP === VNC Password="cobra-angel"
ALTERATOR SETUP === Default network device: "eth0"
ALTERATOR SETUP === IPv4: "10.0.2.15/24"
ALTERATOR SETUP === IPv6: "fec0::bee1:6f2d:ce4a:9c1d/64
fe80::6a0:ddd0:df03:e44d/64"
PORT=5900
</source>
</source>
The ./boot/vmlinuz will contain symlink to the Linux kernel.


'''Step 3.''' Create the GPT table with two partitions on the microSD card:
To connect to a serial console (usually /dev/ttyUSB1) using GNU/screen use the command below:
* The first partition must contain specific GUID 2E54B353-1271-4842-806F-E436D6AF6985
* The second partition is a typical Linux Filesystem GUID 0FC63DAF-8483-4772-8E79-3D69D8477DE4
The example command for <tt>/dev/sdX</tt>:
<source lang="shell">
<source lang="shell">
$ sgdisk -g --clear \
$ screen /dev/ttyUSB1 115200
        --new=1:2048:67583 --change-name=1:bootloader --typecode=1:2E54B353-1271-4842-806F-E436D6AF6985 \
        --new=2:264192:    --change-name=2:root      --typecode=2:0FC63DAF-8483-4772-8E79-3D69D8477DE4 \
        "/dev/sdX"
</source>
</source>


'''Step 4.''' Write the bbl+Linux kernel to the first partition of microSD:
* connect via vnc using the remote-viewer vnc client from the virt-viewer package:
<source lang="shell">
<source lang="shell">$ remote-viewer vnc://<ip_address>:<Port></source>
$ dd if=boot/vmlinuz of=/dev/sdX1 bs=4M status=progress
</source>


'''Step 5.''' Create filesystem on second partition of microSD. Mount it and untar the archive with rootfs:

<source lang="shell">
$ mkfs.ext4 /dev/sdX2
$ mount /dev/sdX2 /mnt
$ tar -xpvf regular-jeos-latest-riscv64.tar.xz -C /mnt/
$ umount /dev/sdX2
</source>


Now, microSD is ready to use with HiFive Unleashed.

Regular image builds are intended for testing and development of the RISC-V (rv64gc) port of Sisyphus repository.

Additional information:

The images are intended to be run in qemu without modification and written according to the instructions to removable storage devices for sequent loading on target boards. Аfter booting from one of the images below, use the following credentials to login:

 login: root
 password: altlinux

For images with graphics the user will be asked to complete the initial setup in a graphical setup wizard at the first boot. During configuration, you can set the timezone, root password, password for connecting to VNC (if launched via VNC), create a new user, etc. On boards without a graphics adapter the graphical setup wizard must be run via VNC.

QEMU

The img.xz images must be unpacked and run according to the instructions: Ports/riscv64/QEMU.

HiFive Unmatched and Unleashed

Images write in instructions are available on the board pages: HiFive Unmatched and HiFive Unleashed.

VNC

Connecting via VNC (not the vnc provided by the qemu emulator) requires :

  • enable vnc mode in alterator-setup by uncommenting or adding a line to /etc/alterator-setup/config:
ALTERATOR_SETUP_VNC=1

or add a --vnc=1 argument for alt-rootfs-installer when it writes to a removable storage device.

  • connect via a serial port and wait for information about the address and VNC connection password:
localhost login: ALTERATOR SETUP === VNC access enabled
ALTERATOR SETUP === VNC Password="cobra-angel"
ALTERATOR SETUP === Default network device: "eth0"
ALTERATOR SETUP === IPv4: "10.0.2.15/24"
ALTERATOR SETUP === IPv6: "fec0::bee1:6f2d:ce4a:9c1d/64
fe80::6a0:ddd0:df03:e44d/64"
PORT=5900

To connect to a serial console (usually /dev/ttyUSB1) using GNU/screen use the command below:

$ screen /dev/ttyUSB1 115200
  • connect via vnc using the remote-viewer vnc client from the virt-viewer package:
