fxload - EZ-USB utility program
- 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.
