Two types of reset exist for TE USB FX2 module but four methods are possible: 2 (reset type) * 2 ( with or without baseboard).
Reset types | Description | Derived methods |
---|---|---|
Power-on reset | The simpler way to achieve a power-on reset is to manually detach and reconnect the power supply | (Method 1) for a TE USB FX2 module without baseboard, the power supply source is the USB port: detach and reconnect the USB port |
(Method 2) for a TE USB FX2 module with baseboard, the power supply source is the external power supply: detach and reconnect the external power supply | ||
Powered reset | A switch or a button is used to assert the reset pin of the Cypress USB FX2 microcontroller and FPGA chip. | (Method 3) for a TE USB FX2 module without baseboard,
|
(Method 4) for a micromodule with baseboard, button S1 on its baseboard can be used to assert the reset: push button S1. |
The firmware actually changes (it is retieved from EEPROM and runs on USB FX2 microcontroller's RAM) only when
The Logic Architecture Layer (FPGA image aka FPGA bitstream) actually changes (the SPI Flash content programs/configures the FPGA) only when .
