    On WB15EVK, is the OTG_ID pin on the connector attached to MX8MM_IOMUXC_SAI3_MCLK_GPIO5_IO2 ? In the Yocto patch that appears to be the case in the pinctrl definitions but that GPIO appears to be unused in that patch. I’ve tried using the extcon-usb-gpio driver with GPIO5_IO2 but no change is detected. I’ve operated the OTG port by forcing it to host/peripheral mode in the dts so it’s working fine for me without role switching. Since there’s no schematic available, can you clarify the OTG port’s OTG_ID pin wiring?

    Thanks,
    Matt

    Hi,

    Yes, my SOM has J103.

    Are the schematics available for the MOZART-Interposer_R003 and WB10AT_EVB_R004 boards?

    Hi Matt,

    OK, I can share those files with you.
    But I only have WB10AT_EVB_R003 version.
    There are very small differences between R003 and R004.
    You can download it from link in below.

    MOZART-Interposer_R003
    WB10AT_EVB_R003
    Download password is “ohporter” and link will expire in 4/27.
