Hi, I built an OE/Yocto IoT device to include kernel modules of usb_wwan, usbserial, mwifiex_sdio, mwifiex etc, there is one udev from meta-freescale/recipes-core/udev/udev-rules-imx/10-imx.rules
# ls /etc/udev/rules.d 10-imx.rules touchscreen.rules My device does not have a touchscreen so that touchscreen.rules should not be there. The 10-imx.rules does not define any kernel modules usb_wwan, usbserial, mwifiex_sdio, mwifiex, the device does not have video or any input # cat /etc/udev/rules.d/10-imx.rules KERNEL=="mc13783_connectiv*", NAME="mc13783_connectivity" # Anyone has readonly permission to IIM device file KERNEL=="mxc_iim", MODE="0444", SYMLINK+="mxc_mem" KERNEL=="mxs_viim", MODE="0444", SYMLINK+="mxc_mem" KERNEL=="mxc_ipu", MODE="0666" KERNEL=="mxc_vpu", MODE="0666" SUBSYSTEM=="video", MODE="0660" KERNEL=="fb[0-9]", MODE="0660", GROUP="video" KERNEL=="gsl_kmod", MODE="0660", GROUP="video" KERNEL=="galcore", MODE="0660", GROUP="video" How can I define udev in recipes to make the system to load kernel modules of usb_wwan, usbserial, mwifiex_sdio, mwifiex in boot? Thank you. Kind regards, - jh
