Installation

Install from source:

Building hidapi requires libusb headers and cython. On Arch Linux they can be obtained from the repositories by installing packages libusb and cython. Debian based distributions will have packages libusb-1.0-0-dev and cython.

On Windows you will also need the correct compiler for your Python version. See this page for more information on setting up the compiler.

Building python-evic:

$ git clone git://github.com/Ban3/python-evic.git
$ cd python-evic
$ python setup.py install

Allowing non-root access to the device

The file udev/99-nuvoton-hid.rules contains an example set of rules for setting the device permissions to 0666. Copy the file to the directory /etc/udev/rules.d/ to use it.

Usage

See --help for more information on a given command.

Encrypt/decrypt a firmware image:

$ evic convert in.bin -o out.bin

Dump device data flash to a file:

$ evic dump-dataflash -o out.bin

Upload an encrypted firmware image to the device:

$ evic upload firmware.bin

Upload an unencrypted firmware image to the device:

$ evic upload -u firmware.bin

Upload a firmware image using data flash from a file:

$ evic upload -d data.bin firmware.bin

Use --no-verify to disable verification for APROM or data flash. To disable both:

$ evic upload --no-verify aprom --no-verify dataflash firmware.bin
