USB FX2 microcontroller's EEPROM firmware: FX2 microcontroller reads/writes IIC EEPROM

Tip

If the TE USB FX2 module exit from reset or is powered on, the IIC EEPROM content programs/configures the USB FX2 microcontroller RAM

...

Note

The firmware actually changes (it runs on USB FX2 microcontroller's RAM) only when

  • the user resets the TE USB FX2 module (in fact a Powered reset);
  • the user powers off and power on the TE USB FX2 module (in fact a Power-on reset);
  • the user writes the USB FX2 microcontroller's RAM (but the new firmware is lost if the TE USB FX2 module goes under reset or power off/on cycle).

USB FX2 microcontroller's RAM firmware: IIC bus is not used, only USB connection is used

Note

It is an implicit (or explicit) step necessary to write a new firmware in the IIC EEPROM.

See the section "USB connection is unresponsive" for a description of similarity and difference of (Implicit Two-Step) recovery boot  and (Explicit Two-Step) recovery boot.
