when connecting the board with the TFT display and Aurix TriCore to the EvalBoard with the inverter, the ESR0 led is triggered when pressing the PORST button.
I did some tests and the problem results when connecting the Inhib and GND pin between both boards. The Inhib pin is usually at 3.3V which does not result in any error. However, when pressing the PORST button, the Inhib pin is down to 1V, resulting in the ESR0 led being red.
I think that the ESR0 indicates a fault detected by the Aurix TriCore.

Thanks for your help.
