Pin Configuration Issue in MCUXpresso IDE

hyf_grass — Mon, 16 Mar 2026 10:24:24 GMT

I have installed MCUXpresso IDE v25.6.136 on my computer and downloaded **SDK_25_12_00_MCXE31B** from the official website.

I imported the example projects from the SDK into the IDE, and they can be compiled normally. However, when I open the configuration tool inside the IDE to configure pins, an error appears on this interface. Please help me.

The processor MCXE31B is not supported or processor data is not available. Please check your network connection.

But my network is working fine.

Hi @hyf_grass

The latest public MCUXpresso IDE is version 25.06 and by default it contains MCUXpresso Config Tools 25.06.

We need to update the Config Tools in the IDE to the latest version. Please refer guideline how to do it, it's available here:
