Vnish Firmware 1.3.6 is now available, bringing an important improvement for ASIC miners using CVitek (CV) control boards.
The main highlight of this release is automatic startup on CV control boards. Vnish can now initialize and remain active after reboots without requiring additional utilities such as Hashcore Toolkit or Phoenix service.
๐ Automatic Startup on CVitek Control Boards
For CVitek users, this is the most important change in Firmware 1.3.6.
Vnish now automatically initializes on supported CV control boards and persists across reboots. There is no need to rely on additional startup utilities just to make sure the firmware launches again after restarting the miner.
For a single ASIC, this makes everyday operation simpler. For a mining farm with dozens or hundreds of machines, automatic startup can save a lot of unnecessary manual work after power interruptions or scheduled reboots.
โ๏ธ Less Software, More Automation
Modern ASIC mining is increasingly about automation. A miner should be able to restart, initialize its hardware and return to operation without requiring an operator to manually intervene every time.
CVitek control boards have their own architecture and requirements, so reliable startup support is an important part of making custom firmware work smoothly across different Antminer platforms.
With Firmware 1.3.6, Vnish takes another step toward a more self-contained firmware environment for CV-based miners.
๐งน CV Control Board Cleanup Fix
Version 1.3.6 also includes a fix for the log cleanup routine when uninstalling Vnish firmware on CVitek control boards.
This is a smaller change compared with automatic startup, but it improves the firmware removal process and helps ensure that unnecessary logs are properly cleaned up when Vnish is uninstalled.
๐ง Why CVitek Support Is Important
Control boards are a critical part of every ASIC miner. They connect the firmware with the hashboards, power supply, sensors and other components that keep the machine running.
That means firmware compatibility is not simply about supporting the ASIC chips themselves. Proper control-board support is essential for reliable startup, monitoring, configuration and recovery.
Vnish has been expanding support for different Antminer control-board platforms, including CVitek, Xilinx and Amlogic. Firmware 1.3.6 continues this work with a practical improvement focused specifically on CV users.
โ ๏ธ Important: Use Hashcore Toolkit 1.7.4 or Later
Before installing or updating to Vnish Firmware 1.3.6, make sure you are using Hashcore Toolkit v1.7.4 or later.
The latest Toolkit expands support for modern Bitmain stock firmware and adds support for additional Antminer configurations, including CVitek-based devices.
For the latest installation instructions, see the official Vnish firmware installation guide.

๐ Vnish Firmware 1.3.6
Vnish Firmware 1.3.6 is a focused update, but the main improvement is especially useful for CVitek control board users.
Automatic startup means fewer dependencies and less manual intervention after reboots, while the CV cleanup fix improves the uninstall process.
If your Antminer uses a supported CVitek control board, Firmware 1.3.6 brings a simpler and more automated Vnish experience.
