However, after reviewing the "Layerscape Linux Distribution POC User Guide," I noticed that it mentions there is no support for the GPIO feature on the LS1012A. Additionally, I built the Yocto-Qoriq SDK from the styhead branch, but in the final root filesystem, I could not find the usual export or unexport files, nor was there a gpio folder in the /sys/class/ directory. I am therefore unsure how to export the sysgpio pins on this platform. Could you please advise on how to proceed?</SPAN></P> Tue, 20 May 2025 04:24:21 GMT Dhanyalakshmi 2025-05-20T04:24:21Z https://community.nxp.com/t5/Layerscape/Inquiry-Regarding-Exporting-GPIO-Pins-on-LS1012A-Controller/m-p/2100297#M15768 <P><SPAN>Hi team,</SPAN></P><P><SPAN>I am working with the LS1012A controller and would like to export its sysgpio pins in order to connect some devices on our custom baseboard.
