TPS65982: No connection to TPS65982-EVM with FTDI adapter module UMFT4222EV

Part Number: TPS65982
Other Parts Discussed in Thread: , TPS65981EVM, TPS65981

Hello,

For a project with USB type C in alternate mode, I bought a TPS65982-EVM. For flashing a new firmware on the board, I tried to connect a ftdi-based adapter to the board over SPI and I²C.

All the user guides don't explain which FTDI chip is possible to communicate with the TPS65982 over the Application and Host Interface Tool. So I bought the module UMFT4222EV, that is possible to communicate with SPI or I²C devices over USB. I don't want to buy the expensive Aardvark I2C/SPI Host adapter with the same functionalities.

By connecting the FTDI module with the TPS65982-EVM and installing the correct FTDI driver, I still cannot communicate or flash the board. In the Application Tool I got this error message:

Exception Encountered during I2C Address Sweep:No FTDI I2C channels (I2C_GetNumChannels) detected, exiting....

<type 'exceptions.Exception'>

 

Traceback (most recent call last):

File "acConfigurationGui.py", line 2093, in sweep_handler

File "hw_interface.pyc", line 166, in hw_open

Exception

Is the FTDI module able to communicate over the TI Tools? If not, can you give me a list of possible modules?

Best Regards,

Jan Just

    Hi Jan,

    Welcome to E2E!  Could you possibly get your hands on the TPS65981EVM? It's basically the same device with a different package, but it has a FTDI board that comes with it.  The FTDI board can be broken off and used with the TPS65982, which is highly recommended.

    With the FTDI board (it comes with the TPS65981 EVM board), you will be able to program the firmware on the TPS65982 EVM's.

    Also, make sure to download the Applications Customization GUI instead of the Host interface GUI: http://www.ti.com/lit/ug/slvuar8a/slvuar8a.pdf.
