TPS6598x host interface tools with FTDI

Other Parts Discussed in Thread: TPS65982, TPS65982-EVM

Hi,

I’m trying to program the TPS65982-EVM (Development board) via i2c with FTDI – FT232H chip, sadly I cant seem to be able to communicate with the TPS65982 as the TPS6598x host interface tools keeps returning status code 3 (FT_DEVICE_NOT_OPENED)

Regards,

Jeff

    Hi,

    The FTDI option requires you to connect the I2C SDA, SCL and GND of the TPS65982 device connect to FTDI chip. We have included the drivers for "USB2MANY" FTDI board and Aardvark in our Host interface utility tool. Please select these FTDI devices and check again.

    Hi,

    Thanks for the quick reply, the more I look into things the more it looks like the MPSSE I2C side of the FTDI is not being initializing correctly when trying to use the TI Host interface utility tool. Yes I'm not using a "USB2MANY" board - I'm just tying to use a FT232HQ breakout I've got to program/communicate with the TPS65982 and not buy a aardvark (the price is way to high).

    I've checked the SDA and SCL lines with a logic analyse and they're always high, I don't even see the i2c start sequence (SDA low while SCL high) when running the TI Host interface utility tool.

    Yes my SDA,SCL and ground are connected as below.

    SDA  = TPS65698 (pin 20 of J2) > FT232H (ADBUS1 and ADBUS2)

    SCL = TPS65698 (pin 18 of J2) > FT232H (ADBUS0)

    GND = TPS65698 (pin 01 of J1) > FT232H ground

    Regards,

    Jeff

    Hi,

    Can you scan for the I2C address you have for the device in the Host utility Tool? You can use 'I2C Scanner' Option at the bottom end of the tool. Use the I2C address detected there in the configuration section. Can you check using I2C Port 1 in configuration section too? Let me know if this helps.

    Regards,
    Arun
