DWC3 driver uses of_usb_get_phy_mode() which is implemented in drivers/usb/phy/of.c and in bare minimal configuration it might not be pulled in kernel binary. In case of ARC or ARM this could be easily reproduced with "allnodefconfig" +CONFIG_USB=m +CONFIG_USB_DWC3=m. On building all ends-up with: ---------------------->8------------------ Kernel: arch/arm/boot/Image is ready Kernel: arch/arm/boot/zImage is ready Building modules, stage 2. MODPOST 5 modules ERROR: "of_usb_get_phy_mode" [drivers/usb/dwc3/dwc3.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 ---------------------->8------------------ This was affecting Lede in case of CONFIG_ALL_KMODS=y. The patch is already scheduled for v4.12 and once it is backported to 4.9.y it must be removed from here. Note this patch makes sense not only for ARC instead it fixes a generic issue which may affect more arches and platforms thus putting it in "generic/" folder.

This is the buildsystem for the LEDE Linux distribution. Please use "make menuconfig" to choose your preferred configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your LEDE Community http://www.lede-project.org
