+FXLOAD is conveniently able to download firmware into FX, FX2,
+and FX2LP EZ-USB devices, as well as the original AnchorChips EZ-USB.
+It is intended to be invoked by hotplug scripts when the unprogrammed
+device appears on the bus.
+
+Primarily as an aid for developers, this can also be used to update
+firmware on devices which boot from I2C serial EEPROMs. For that
+use, as well as downloading firmware to all other off-chip memory,
+a second stage loader must first be downloaded.
+
+The distribution includes "a3load.hex", which is a simple second stage
+loader that works with all the EZ-USB products listed above. If you
+want to write to an EEPROM, you can use the appropriate version of the
+"Vend_Ax" code provided with the Cypress developer kit.
