3 Connectors

Top

3.1 Aardvark 1 and Aardvark 2

There are the two boxed connectors at the bottom of the EEPROM Socket Board which are used to connect the board to an Aardvark I2C/SPI Host Adapter or a Cheetah SPI Host Adapter. These two connectors are cross-connected, so it does not matter which one is used. In most cases, you will only want to connect a single adapter to the EEPROM Socket Board at a time.

The second connector is available to connect to a protocol analyzer or to cross connect with another adapter for testing purposes. For example, an Aardvark adapter or a Cheetah adapter can be connected to the board through Aardvark 1 to program the memory chip. At the same time, a Beagle I2C/SPI Protocol Analyzer can be attached to Aardvark 2 to monitor the bus while the chip is being programmed to ensure that the data on the bus is correct.

3.2 External

Figure 7: The External Connector (J1) provides the developer with a quick and easy way to interface or monitor any or all of the EEPROM Socket Board signals.

All the signals on the board are available for external monitoring through the External connector (J1). The two VIN pins allow a user to use an external power source to power the memory device. Please refer to the “Programming a Device” section for more information.

3.3 Powering the EEPROM Socket Board 

To power the EEPROM Socket Board, the Cheetah or Aardvark adapter must be configured to send target power to the board. This can be accomplished via the Rosetta Language Bindings, the Flash Center software, the Aardvark Control Center Software or the Cheetah GUI Software. When powered-on, the board’s Power LED will be lit.

3.4 Cross Connecting Aardvark Adapters and/or Cheetah Adapters

When cross connecting two adapters, the board must be powered on. Otherwise, results may be unpredictable. If you experience problems, please make sure that the Power LED on the board is lit.
