Description:

This package contains utilities for downloading firmware to EZ-USB
devices. EZ-USB devices use 8051-based microcontrollers that have been
enhanced with registers, buffers, and other device-side support for
USB transactions.

It currently supports devices based on the Anchorchips EZ-USB, as well
as the Cypress EZ-USB FX (which is almost completely source
compatible) and EZ-USB FX2 (which is not). All of these support full
speed (12 Mbit/sec) transfers. The FX2 also supports high speed (480
Mbit/s) transfers, introduced in USB 2.0.

This version of FXLOAD supports optional use of two-stage loading,
where special device firmware is used to support writing into off-chip
memory such as RAM (when firmware neeeds more than about 8 KBytes of
code and data) or, for firmware development, I2C serial EEPROM.
