NanoVNA - Very tiny handheld Vector Network Analyzer

About

NanoVNA-H and NanoVNA-H4 are very tiny handheld Vector Network Analyzers (VNA). They are standalone portable devices withLCD and battery. This project aims to provide improved firmware for this useful instrument for enthusiast.

This repository contains the source code of the improved NanoVNA-H and NanoVNA-H4 firmware.

The documentation describes the build and flash process on a MacOS or a Linux (Debian or Ubuntu) system, other Linux (or even BSD) systems may behave similar.

Prepare ARM Cross Tools

UPDATE: Recent gcc version works to build NanoVNA, no need to use old version.

MacOSX

Install cross tools and firmware updating tool.

brew tap px4/px4
brew install gcc-arm-none-eabi-80
brew install dfu-util

Linux (ubuntu)

Download arm cross tools from here.

wget https://developer.arm.com/-/media/Files/downloads/gnu-rm/8-2018q4/gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2
sudo tar xfj gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2 -C /usr/local
PATH=/usr/local/gcc-arm-none-eabi-8-2018-q4-major/bin:$PATH
sudo apt install -y dfu-util

Debian

sudo apt install gcc-arm-none-eabi
sudo apt install -y dfu-util

Fetch Source Code

Fetch the firmware source and the submodule, do this once to initialize your local clone from GitHub:

git clone https://github.com/DiSlord/NanoVNA-D.git
cd NanoVNA-D
git submodule update --init --recursive

Update Source Code

To get updates from the GitHub repository, go to your NanoVNA-D directory and type:

git pull

Build the NanoVNA-H Firmware

Go to your NanoVNA-D directory and type:

export TARGET=F072
make clean
make

Build the NanoVNA-H4 Firmware

Go to your NanoVNA-D directory and type:

export TARGET=F303
make clean
make

Flash Firmware

When the build of your firmware is finished, you can flash it onto your NanoVNA device. First, let the device enter DFU mode by one of following methods.

  • Open the device and jumper BOOT0 pin to Vdd pin when powering the device.
  • Select menu Config->DFU (needs recent firmware).
  • Press the jog switch on your -H4 when powering the device.

Then, flash the firmware using dfu-util via USB.

For NanoVNA-H:

Go to your NanoVNA-D directory and type:

dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D build/H.bin

For NanoVNA-H4:

Go to your NanoVNA-D directory and type:

dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D build/H4.bin

Or simply type directly after building the firmware (for both variants).

Go to your NanoVNA-D directory and type:

make flash

Ignore the apparent error message during flashing

The low-level tool dfu-util displays a lot of information that is very useful especially for developers, but can confuse the user. In particular, please ignore the message about corrupt firmware, this is the normal behaviour of the unit before clearing the status. It is important to note that after clearing the status, there is no longer an error condition present.

...
Determining device status...
DFU state(10) = dfuERROR, status(10) = Device's firmware is corrupt. It cannot return to run-time (non-DFU) operations
Clearing status
Determining device status...
DFU state(2) = dfuIDLE, status(0) = No error condition is present
...

Companion Tools

There are several numbers of great companion PC tools from third-party.
