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 contained in a FPGA bitstream) actually changes (the SPI Flash content (FPGA bitstream) programs/configures the FPGA) only when .
