I've configured and the built the yocto for recipe core-image-minimal-dev. Which works fine. Now I needed to add modifications for kernel and configurations for Quectel EC25 module. I followed instructions from https://www.yoctoproject.org/docs/1.6/dev-manual/dev-manual.html#configuring-the-kernel My linux-imx_4.1.15.bbappend looks like this FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:" SRC_URI += "file://0001-Add-Quectel-EC25-USB-Serial-Driver-Support.patch \ file://usb_serial.cfg" Both .path and .cfg are located under meta-quectel-community/recipes-kernel/linux. When I do bitbake -c cleansstate linux-imx and build the kernel again with bitbake linux-imx only 0001-Add-Quectel-EC25-USB-Serial-Driver-Support.patch patch is getting applied but configuration changes in usb_serial.cfg are getting ignored. I saw similar issue reported https://lists.yoctoproject.org/pipermail/yocto/2016-December/033475.html but the solutions didn't help me. Can you help me with a proper way to change the kernel configurations with linux-imx image? 84014 1 randy.macleod 2019-05-30 15:20:11 +0000 imx issue need to be reported on the appropriate github page now.
