Tuner GUI Connection fails PSOC4248AZI-L485

Hi,

I have looked through some similar threads but I haven't come to a solution so far.

I am using a custom PSOC4248AZI-L485 Board and I cannot launch the tuner.

I have configured the EZI2C according to the settings using the pins P3_0/P3_1 , but when using the MiniProg3 the connection always fails.

Any clue what I am doing wrong?

Programming the device works fine.
