3 hours ago Hi, this is a setting in the eeprom. The byte to change is the one below [image: bild.png] It determines if a pair of i/os are inputs or outputs. It's the Extended PDI Configuration Register. See section 12.14.30 in http://ww1.microchip.com/downloads/en/devicedoc/00001909a.pdf You can find details on the eeprom contents in section 12.8 in the same document. There is no way around reading the datasheet for these kind of details.
Change the value above, and upload the new firmware to LAN9252 in Twincat. You might need to change the "bitlen" field in the pdos above in the xml file. Hope it works.

Hello May I ask a question LAN9252 comes with 16 GPIO built-in, and I can run the LAN9252 core board using the Dig_8IN_8OUT.xml file you provided. I want to configure it with 12 digital inputs and 4 digital outputs, but I tried for 2 days but couldn't succeed. I have no choice but to seek your advice
