fx3lafw

This is an open source firmware for using a Cypress FX3 USB controller as a logic analyzer with sigrok. It does not rely on any libraries or tools provided by Cypress under license.

This is a work in progress, some functionality such as HighSpeed compatibility is not yet implemented.

Currently supported hardware is the CYUSB3KIT-003 "SuperSpeed Explorer Kit".

There is a branch of libsigrok on github which contains the host side support.

Building

On Gentoo, use crossdev -t arm-none-eabi to build toolchain and newlib.

The firmware image can then be built using make.
