Pin Configuration Issue in MCUXpresso IDE

hyf_grass — Mon, 16 Mar 2026 10:32:36 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 pops up on this interface:

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

But my network is working fine. Please help me.

You can download the MCXE31B config tool data from the official website.

After decompressing the folder, place the relevant files in the corresponding folder.

C:\ProgramData\NXP\mcu_data_25.06

Then you will successfully open the pin config in the MCUXpresso IDE.
