My raspberry PI3B have istall volumio 2.246, and i try to build es9018k2m DAC driver for volumio，
so i download kernel source code with ubuntu 12.04,
git clone github.com/volumio/raspberrypi-linux
git clone git://github.com/raspberrypi/tools.git
then get the kernel config file with the runing volumio 2.246
$ sudo modprobe configs
then under the ubuntu, i cross-compile the kernel source code,
$ sudo zcat config.gz > .config
modify kernel Makefile as ARCH=arm; CORSS_COMPILE=…/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
$ sudo make menuconfig <- only to save it
$ sudo make
$ sudomake modules_install INSTALL_MOD_PATH=…/modules
then copy arch/arm/boot/zImage to SD’s /boot partition, modules to /lib/modules/
finally add kernel=zImage to /boot/config.txt
but kernel panic, i don’t known why? can some one can help me! thanks,
volumio 2.246 used kernel 4.9.36 and it will show VOLUMIO version when booting,
