Hello,

I'm working with PSoC 4 (device CY8C4247LQI-BL473). PSoC Creator's version is 4.2.

If I connect an input pin directly to UART component input, it works fine. But when I insert a NOT gate between the input pin and the UART input, I get the following error:

This is the diagram I'm using in the design:

I have seen in some older threads that this error could happen in previous versions of PSoC Creator. Is this possible at all? Or may I'm having a real routing problem? Why the NOT gate's output could not be connect to the UART's input?
Uart component: SCB_P4_v4_0
NOT gate component: not_v1_0
IO pin version: cy_pins_v_2_20
Hope you can help.
Cheers,
Yuri

NOT component is placed into a Universal Digital Block (UDB) programmable logic. Your implementation uses SCB based UART and UDB based NOT gate. Instead, you can optimize the routing by using UDB based components for both UART and NOT components.

Hello GeonaM_26,

I did as you suggested (using both UDB components) and it worked fine.

Thank you for the reply.

Cheers,

Yuri
