- Enable DTBO overlays
This option allows you to enable/disable the DTBO overlays. It uses
uboot-updatescript installed inside rootfs to enable or disable the specific dtbo overlay from extlinux configuration.
- Build third-party DTBO
This option allows you to build the third-party DTBO. It builds and installs the dtbo using the
device-tree-compilerutility.
Connectivity
This feature allows you to configure different connectivity options.
- Configure network
This option allows you to configure network using
nmtui.
Advanced Options
This feature allows you to configure different advanced options.
- Install GPU library
This option allows you to install Mali GPU library and enable OpenGL support.
It uses
apt installto install the mali library fromuserdatapartition and enables thegl4eslibrary support for converting OpenGL-ES context to OpenGL.Tip
Use
gl4esprefix with your desired application to run that application with OpenGL.Example:
gl4es supertuxkart
User Settings
This feature allows you to configure different user settings.
- Change system password
This option allows you to change the system password. It uses
passwdto change the system password.
- Change hostname
This option allows you to change the system hostname. It uses
hostnamectlto change the system hostname.
Localization
This feature allows you to configure different localization options.

USB Tethering
The latest version of vicharak-config introduces USB Tethering support for seamless SSH access to your Vaaman via the TYPE-C0 USB port. In addition to SSH access, the tethering interface can now share internet from Ethernet to your host machine over USB.
Key Features
Plug-and-play SSH access via USB at a fixed IP (
10.42.0.1)Share internet access over USB when the Vaaman is connected via Ethernet
Service control via both TUI and systemd
Getting latest vicharak-config
USB-tethering can be enabled through latest update of vicharak-config. To get latest version of vichrak-config, run below commands:
Warning
⚠️ Type-C Mode Switching Issues: The Type-C0 port may not reliably switch between host and device modes. Enabling this feature might interfere with other Type-C peripherals, such as USB pen drives. If issues occur, try replugging the device or switching to a different Type-C port.
sudo apt update
sudo apt install vicharak-config
This feature is fully supported only on the latest Linux kernels. We recommend upgrading to the latest kernel version for proper functionality.
sudo apt update
sudo apt install u-boot-menu
sudo apt install linux-5.10.233-vaaman
sudo reboot
Accessing USB Tethering Controls
From the TUI (vicharak-config interface), go to:
> Advanced Options
> USB Tethering
You can Enable/Disable USB Tethering.
Service Control via systemd
The service controlling USB tethering is:
advanced-usb@tethering.service
Commands:
Stop the service:
sudo systemctl stop advanced-usb@tethering.serviceStart the service:
sudo systemctl start advanced-usb@tethering.serviceDisable autostart on boot:
sudo systemctl disable advanced-usb@tethering.serviceEnable autostart on boot:
sudo systemctl enable advanced-usb@tethering.service
SSH Access via USB
Once enabled, connect your host PC to the TYPE-C0 port of the Vaaman and SSH directly:
ssh vicharak@10.42.0.1
This eliminates the need for serial console or IP discovery.
Internet Sharing over USB
If your Vaaman is connected to the internet via Ethernet, the host PC will also get internet access via the USB connection.
This is achieved using appropriate IP forwarding and iptables NAT rules, which are applied automatically by the advanced-usb@tethering.service.
Technical Details
IP Address: Vaaman (USB device):
10.42.0.1, Host (PC): typically10.42.0.2iptables Rules: Automatically configured to allow NAT routing from USB (
usb0) to Ethernet (eth0)IP Forwarding: Automatically enabled during tethering
