Other Parts Discussed in Thread: TPS65987

Hi,

I'm trying to connect to the TPS65987 through an FTDI breakout board ref: UMFT200XD (picture below)

When i try to sweep address i have the error message below :

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

I don't understand because my FTDI device is well recognize and the driver is correctly installed

Maybe i made a schematic mistake but the LDO_3V3 is at 3.3V when i connect the USB cable and the reset is pulling low so the device is correctly powered (and even so, the FTDI Should be detected by the application even if the TPS65987 is off, no ?)

you can find the schematic of my board as attachment if needed

Hi Alan,

I would recommend using either an Aardvark adaptor or the FTDI board that is included with the EVM. It seems like it might be a driver issue, however, we unfortunately do not support other FTDI boards such as this and have not tested with them. Therefore, we are unable to support this.

Thank you,

Hari

Hi Hari,

I was able to communicate by using FTDI 4232H boards and using the same pinout than the EVM Board

Thank you,
